Description

  The present invention relates to a foam composition in which the stability of the generated foam is improved, and dripping is suppressed when sprayed onto a wall surface or the like.

  A cleaning agent can be illustrated as an example of what generate | occur | produces foam and is provided for the use purpose (henceforth a foam composition). In the cleaning agent, a solvent suitable for the object to be cleaned and various components are mixed, and the dosage form is taken into consideration for convenience in use. In particular, in recent years, soaps, laundry detergents, softeners, kitchen detergents, etc., tend to be liquid products.

  Chelating agents, dispersants, surfactants, soaps, polysaccharides and the like are added to the cleaning agent. The action of removing dirt from the object, which is the main purpose of the cleaning agent, is mainly due to the surfactant. The surfactant is adsorbed to the dirt, and the object is cleaned by separating the dirt from the object. During cleaning, bubbles are generated by the components contained in the cleaning agent. This foam prevents the separated dirt from adhering to the object again, and increases the contact time of the surfactant to the dirt component. The effect is expected.

  A method using a glyceroglycolipid surfactant is disclosed as a method for improving foam foaming properties (Patent Document 1). However, since the frequent use of a surfactant also has an impact on the environment, an alternative technique is disclosed. Is required.

  In addition, foam is generated by the action of the surfactant contained in the foam composition. This foam prevents the separated dirt from adhering to the object again, and the surfactant is added to the dirt component. The effect of prolonging the contact time is expected. In order to lengthen the contact time, the property of staying at the place where the bubbles do not flow is required.

  In order to improve the adhesiveness of the foam, there is a method for suppressing the falling of the foam. As such a method, a spray liquid cleaning composition containing a specific cellulose, a surfactant and water (Patent Document 2), and a composition containing specific cellulose fine particles and a liquid dispersion are sprayed. The spray agent (patent document 3) with which the apparatus was filled is disclosed.

  However, the components that can be used in these techniques are limited to specific ones, and the implementation has been difficult. Moreover, although methods for suppressing dripping of the cleaning agent are disclosed in JP-A-9-143498, JP-A-2011-225663, etc., these all suppress dripping of “liquid”. Yes, it does not suggest or suggest that the “bubbles” fall off as in the present invention.

  The present invention improves the stability of foam such as foam retention without using a lot of surfactant, the fineness of foam, and the dripping of foam generated by spraying on the surface to be cleaned. The purpose is to enhance the cleaning effect by suppressing the above.

  Examples of foam compositions that can utilize the technology according to the present invention include hair shampoos, body shampoos, body soaps, hand soaps and facial cleansers such as body cleaners and residential cleaners, as well as hair colorants ( Hair color), cosmetics, shaving foam, bath foaming agent (bubble bath), hair remover, hair restorer, insecticide, bleach, fire extinguishing agent, food for ornamental fish, fertilizer for gardening, automobile tires and leather shoes An example of a polishing agent is given. All of these are common in that the purpose of use is achieved by generating bubbles, and the improvement in the holding power of bubbles and the improvement in the fineness of the bubbles, like the cleaning agent, lead to an improvement in the feeling of use. In addition, for example, in the case of a cleaning agent, it is possible to expect the cleaning effect by the surfactant more because the foam, that is, the surfactant stays in the soiled portion for a long time. In the case of a hair remover and a hair restorer, the effects of the medicinal components and the like contained in the foam composition can be fully enjoyed. Therefore, a method for improving the foam foaming property as well as the foaming property is required.

  The inventor of the present application has conducted intensive research to solve the above-mentioned problems, and the stability of foam generated when using a foam composition such as a cleaning agent, that is, the improvement of foam retention, the improvement of fineness of foam In order to improve the effect of improving the stability of the foam and suppressing the falling of the generated foam, it is possible to stabilize the foam composition conventionally used by adding fermented cellulose that is naturally decomposed to the foam composition. The inventor has completed the present invention with the knowledge that the property and the efficiency of the cleaning effect can be enhanced and the influence on the natural environment can be suppressed.

  The present invention relates to a foam composition in which the stability of foam is improved and the falling of foam is suppressed by containing 0.03 to 0.6% by mass of fermented cellulose.

  The fermented cellulose used in the present invention is not particularly limited as long as it is a cellulose produced by a cellulose-producing bacterium. Usually, cellulose-producing bacteria are cultured according to known methods, for example, methods described in JP-A-61-212295, JP-A-3-157402, and JP-A-9-121787, and the obtained fermented cellulose is desired. It can manufacture by refine | purifying suitably according to.

  The fermented cellulose of the present invention is combined with one or more polymer substances such as sodium carboxymethylcellulose (CMC-Na), xanthan gum and guar gum according to the method described in JP-A-9-121787. It is desirable. For convenience, the Sun Artist (trademark) PX series and PG series of Saneigen FFI Co., Ltd. can be used.

  The amount of fermented cellulose added can be appropriately adjusted according to the type and amount of components to be dispersed in the foam composition, and the specific gravity of the solid composition, but generally 0.03 in the foam composition. It is -0.6 mass%, Preferably it is 0.03-0.3 mass%. When the added amount of fermented cellulose is 0.03% by mass or less, preferable foam stabilization and dripping suppression effects cannot be obtained, and when 0.6% by mass or more is added, the viscosity increases and handling during use May be difficult.

  More specifically, when particularly improving the stability of the foam composition, that is, the holding power and the fineness of the texture, the amount of fermented cellulose added is preferably 0.03 to 0.6% by mass in the foam composition, preferably Is preferably in the range of 0.03 to 0.3% by mass. On the other hand, when attention is paid to suppressing the falling of the generated foam and the effect is exhibited, the fermented cellulose in the foam composition is 0.03 to 0.6% by mass, preferably 0.06 to 0.00. It is preferable to add 3% by mass.

  The method of adding fermented cellulose to the foam composition is only required to add fermented cellulose as one raw material of the foam composition to be prepared, and since there is no particular limitation on the timing of addition or temperature conditions, a normal production line can be used. There are benefits.

  The foam composition according to the present invention can utilize various components that have been conventionally used without limitation, except that fermented cellulose is an essential component. For example, soaps such as solid soap, powdered soap and composite soap for detergents; anionic surfactants (linear alkylbenzene sulfonates, alkyl sulfates, α-olefin sulfonates, ether sulfates, alkyls) Phenyl polyethylene glycol ether, alkyl polyethylene glycol ether, etc.), nonionic surfactant (polyoxyethylene alkyl ether, fatty acid alkanolamide, alkyl polyglucoside, etc.), cationic surfactant (di-long chain alkyl type quaternary ammonium salt, mono Surfactants such as long-chain alkyl quaternary ammonium salts), amphoteric surfactants (alkyldimethylaminoacetic acid betaine, fatty acid amidopropyl betaine, etc.); inorganic builders (various zeolites, amorphous aluminosilicates, pyrroline) Sodium, sodium carbonate, crystalline sodium silicate, sodium sulfate, sodium tripolyphosphate, etc.), organic builder (aminocarboxylate, hydroxyaminocarboxylate, hydroxycarboxylate, cyclocarboxylate, ether carboxylate, organic carboxylate) Detergency aids such as carbonate polymers; alkaline agents such as carbonates, silicates, phosphates, borates and amines; enzyme agents such as proteases, lipases and amylases; carboxymethylcellulose (CMC), polyethylene Anti-staining agents such as glycol; other bleaching agents, softening agents, foam control agents, fluorescent brighteners, reducing agents, fragrances, dyes, antibacterial agents, and the like can be blended.

  With respect to hair color and car tire polishes, conventionally used components can be used without limitation.

  In addition to fermented cellulose, one or more of gum arabic, locust bean gum, xanthan gum, karaya gum, tragacanth gum, gati gum, alginic acid and salts thereof, starch, hyaluronic acid, pectin, gellan gum, karaya gum, water-soluble hemicellulose What is used with respect to a foam composition in the range which does not inhibit the effect of invention can be used in arbitrary combinations.

  Furthermore, it is also possible to optionally add the above-described cleaning component, fragrance component, enzyme, etc. in a granular gel, or lame or plastic beads added for decorative purposes. In the present invention, even when stored for a long period of time, these additives can be uniformly dispersed throughout the cleaning agent by fermented cellulose.

  Here, an example of the granular gel containing the fragrance component and the cleaning component that can be added to the cleaning agent will be given. As a scent component that can be added to the granular gel, a scent component generally used for perfume can be used without limitation. Specifically, regardless of natural or synthetic, lemon flavor, orange flavor, pine flavor, sandalwood flavor, lavender flavor, geranium flavor, citronella flavor, lemongrass flavor, jasmine flavor, lilac flavor, rose flavor, rosemary flavor, A lime fragrance | flavor etc. are mentioned and 1 or more types of these can be used.

  In addition, by adding one or more components that can be added to the above-described cleaning agent in the granular gel, it is possible to impart a plurality of different effects to the cleaning power with one cleaning agent. These granular gels can be prepared by a known technique.

  Examples of the foam composition to be used in the present invention include, without limitation, those used for the purpose of use by generating foam, such as a hair color and an automobile tire polish, in addition to a cleaning agent. Preferably, it is a body cleaner or a house cleaner, specifically, a hair shampoo or body shampoo, a facial cleanser or a hand soap used for cleaning the body surface, a house floor or wall, In addition to detergents used in bathrooms such as windows and bathtubs, toilets, and toilets, those that exhibit a cleaning effect by retaining a large amount of foam, or hair color, cosmetics, shaving foam, bathing used for hair dyeing and hair dyeing Examples include foaming agents (bubble baths), hair removal agents, hair growth agents, insecticides, bleaching agents, fire extinguishing agents, food for ornamental fish, horticultural fertilizers, polishes for automobile tires and leather shoes, and the like. Moreover, even if it is other than the said washing | cleaning agent, if it is a foam composition used using many foams, the technique of this invention can be used.

  A lot of fine bubbles are generated, and the bubbles are kept without disappearing and stay for a long time, so that the bubbles sufficiently come into contact with the dirty portion of the object. As a result, the surfactants and antibacterial / bactericidal components contained in the cleaning agent will come into contact with the soiled portion for a long time, and the effect will be maximized without increasing the viscosity of conventional detergents. The As a result, it is possible to enjoy a sufficient cleaning effect even with a small amount of cleaning agent, and it is possible to improve the remaining detergent and soap. In addition, since the cleaning agent clings to the object together with the foam, it is more convenient than the liquid cleaning agent, and is used for items with an angled surface or a complicated shape that cannot be used by the liquid cleaning agent. Even available.

  Furthermore, in the case of a hair color, fine bubbles do not fall off and spread evenly over the hair and come into contact with the hair evenly. If it is a hair remover or a hair restorer, it can be expected that the adhesion time to the scalp surface will be prolonged, and the effect of the active ingredient in the preparation can be expected to be improved.

  A fire extinguisher covers the fire source with foam for a long time, shuts off the supply of oxygen and leads to extinguishing. By making the food for the aquarium fish into a foam, the aquarium fish ingests the bubbles floating on the water surface, and the visibility is improved due to the ease of feeding and the unusual appearance. By making the fertilizer for horticulture into a foam, an effect of gradually soaking the fertilizer component over a long time can be expected. Since the appearance is foam, it is thought to contribute in terms of aesthetics. Further, in the case of a polishing agent for automobile tires, fine bubbles uniformly adhere to the tire surface over a long period of time, so that it is possible to polish the tire without uneven coating.

2 The foamed foam was filled into a 200 mL graduated cylinder, and the amount of foam immediately after filling (0 minutes), 5 minutes, 10 minutes, 20 minutes and 30 minutes was measured. Table 2 shows the measurement results.

・ Milcer method Conditions Equipment used: TML24 mill & mixer (manufactured by TESCOM)
Capacity: Use a 180 mL cup Test solution volume: 50 g
Stirring time: 10 seconds Solution temperature: 25 ° C

Table 1 shows thickening polysaccharides and addition amounts used for each test sample. The preparation method is shown below.

<Thickening polysaccharide>
・ Detergent containing 0.06% fermented cellulose (hereinafter referred to as trial 1)
5 g of fermented cellulose preparation (Sun artist * H-PX * fermented cellulose content 60%) was added to a 1 L mug containing 495 g of ion-exchanged water while stirring (propeller stirring 1500 rpm, using 4 blades) and stirred for 10 minutes. . Subsequently, it stirred at 10,000 rpm for 40 minutes with the homomixer, and fermented cellulose was activated. 10 g of the activated fermented cellulose 0.6% aqueous solution was placed in a 200 mL beaker, and 90 g of the detergent solution was added while stirring (propeller stirring 1000 rpm, using three blades), and stirred for 5 minutes.
-CMC (Carboxymethylcellulose) 0.4% detergent (hereinafter referred to as Test 2)
9.6 g of ion-exchanged water was added to 90 g of the detergent solution, and stirred uniformly. Next, 0.4 g of CMC (Serogen F-SB, Daiichi Kogyo Seiyaku Co., Ltd.) was added at room temperature, and dissolved by stirring for 10 minutes (propeller stirring 1000 rpm, using three blades).
-Cleaning agent containing 0.04% xanthan gum (hereinafter referred to as trial 3)
1 g of xanthan gum (San Ace **) was added to a 200 mL beaker containing 99 g of ion-exchanged water while stirring (propeller stirring 1500 rpm, using three blades) and stirred for 10 minutes to obtain a 1% xanthan gum aqueous solution. 6 g of ion exchange water was added to 90 g of the detergent solution, and the mixture was stirred uniformly. Next, 4 g of a 1% xanthan gum solution was added at room temperature, and the mixture was stirred for 5 minutes (propeller stirring 1000 rpm, using three blades) to obtain.
・ HPMC (hydroxypropylmethylcellulose) 0.4% detergent (hereinafter referred to as test 4)
9.6 g of ion-exchanged water was added to 90 g of the cleaning agent solution and stirred uniformly. Next, 0.4 g of HPMC (Metroze 65SH-4000, Shin-Etsu Chemical Co., Ltd.) was added at room temperature and dissolved by stirring for 10 minutes (propeller stirring 1000 rpm, using three blades).

  From the results in Table 2, the bath detergent that was foamed with the addition of fermented cellulose (Trial 1) was not inferior to the others in the amount of foam immediately after foaming, but its holding power stood out as time passed. It became clear that. If the foam retention force is strong, for example, the detergent stays for a long time against dirt such as mold generated in the bathtub, so that it is expected that the effect as a cleaning agent is sufficiently exhibited.

  Subsequently, it confirmed about the quantity of the liquid layer which arises with progress of time. The results are shown in Table 3.

  From Table 3, it was clarified that the addition of polysaccharide slows down the generation of a liquid layer after foaming, particularly the addition of fermented cellulose (Trial 1). When the liquid layer is generated, it means that when the cleaning agent is sprayed on the wall surface of the bathtub or the like, the bubbles are more easily slipped off due to the generation of the liquid layer. Therefore, the slower the generation of the liquid layer, the better the adhesion of the detergent, and it was found that the detergent to which fermented cellulose (Trial 1) was added was also excellent in this respect.

  Furthermore, the retention rate of foam was determined. The results are shown in Table 4. Here, the retention rate of bubbles indicates the amount of bubbles immediately after foaming is 100% and indicates how much the amount of bubbles (excluding the liquid layer) remains over time.

  From the results shown in Table 4, 70% or more of the generated foam was retained even after 30 minutes had elapsed with the addition of fermented cellulose (Trial 1). This was a result linked to the amount of foaming in Table 1. And after 30 minutes, since the retention rate of bubbles rapidly decreases, it is presumed that the problem that bubbles remain in actual use is unlikely to occur.

Experimental example 2
Four types of polysaccharides used in Experimental Example 1 (see Table 1) were added to the face wash of the following formulation, and the state of foam after foaming was confirmed with a microscope. The photograph at the time of observation is shown as FIG.

<Prescription for face wash (foam type face wash)>
Sodium cocoylglycine 30% solution 16.7 parts Sodium lauroamphoacetate 30% solution 10 parts Polyoctanium-39 0.1 part 1.3-Butylene glycol 5 parts Glycerin 5 parts Methylparaben 0.1 part
Sodium hydroxide
100 parts in water

<Method for preparing face wash>
Sodium cocoylglycine 30% solution, sodium lauroamphoacetate 30% solution, polyoctanium-39, 1.3-butylene glycol, glycerin, and methylparaben were stirred and dissolved at 60 ° C. Next, the resulting solution was cooled to room temperature, adjusted to pH 8.3 with sodium hydroxide, and used as a face wash.

<Measurement method>
1 Each polysaccharide was added to the face wash prepared above and foamed for 10 seconds using the Milcer method (conditions are the same as in Experimental Example 1).
2 A small amount of foam was placed on a slide glass, a space was formed with a slit having a height of 0.15 mm, and a cover glass was covered.
3 The state of the foam 5 minutes after foaming was photographed with a microscope (magnification 150) (see FIG. 1).

<Result>
As shown in the photograph shown in FIG. 1, in the facial cleanser to which fermented cellulose (Trial 1) and HPMC (Trial 4) were added, the bubbles were finer than the others.

Experimental example 3
In the same manner as in Experimental Example 2, the polysaccharide was added to a commercially available hand soap (Kao: Biore), and the same operation was performed to confirm the state of bubbles. The photograph taken is shown in FIG.

<Result>
As shown in the photograph shown in FIG. 2, in this experiment as well, remarkably fine bubbles were obtained in the hand soap to which fermented cellulose (Trial 1) and HPMC (Trial 4) were added. In particular, in the hand soap using fermented cellulose (Trial 1), the amount of bubbles at the time of bubbles was larger than that of HPMC (Trial 4), and the usability was further improved.

Experimental Example 4
With respect to a commercially available residential cleaner (Kao: Magiclin), the same operation as in Example 1 was performed to evaluate the bubbles filled in the graduated cylinder (the amount of foam, the amount of liquid layer, the retention rate). . The results are shown in Tables 5-7.

  From Table 5, it was found that bubbles remained for a long time with respect to the indoor cleaning agent to which fermented cellulose (Trial 1) was added. Residential cleaners are intended to be used around kitchens (around ventilation fans and stoves). In this way, the amount of foam is large and the foam remains for a long time. It becomes possible to exhibit the effect of. Specifically, it becomes possible to replace pickling washing with foam.

  From Table 6, it was found that the addition of fermented cellulose (Trial 1) produced a liquid layer later than the others. As described above, when the generation of the liquid layer is slow, the bubbles do not flow down together with the liquid layer, so that the bubbles remain in the soiled portion, and a preferable cleaning effect is expected. Since the amount of the liquid layer generated after 30 minutes is close to that of a blank product to which nothing is added, it is considered that there is no difference in usability during actual use.

  From Table 7, it was found that with the addition of fermented cellulose (Trial 1), the foam retention was significantly improved. The high foam retention rate correlates with the results shown in Table 5, and it is expected that the foam stays in the soiled portion for a long time, and it is considered that the cleaning action can be exhibited more effectively.

Experimental Example 5
Experiments were conducted to confirm that the retention of foam was improved by adding fermented cellulose to various cleaning agents.

  Using commercially available detergents described below, prepare a detergent containing 0.06% fermented cellulose and a detergent containing 0.4% CMC in the same manner as in Experimental Example 1, and perform the same operations as in Experimental Example 1. It was made to foam and evaluated. The results are shown in Tables 8-11.

Commercial products ・ Body soap (milk soap: Kewpie baby soap foam type)
・ Laundry detergent (Lion: Top)
・ Hair color shampoo (Kao: Pretty Men's Bubble Color)

<Preparation method>
1. A 0.6% aqueous solution of fermented cellulose was prepared in the same manner as in Experimental Example 1.
10 g of the 2.1 aqueous solution or fresh water was weighed into a 200 mL beaker, 90 g of a commercially available detergent was added, and the mixture was stirred for 5 minutes (propeller stirring, 500 rpm, using three blades).
The liquid obtained in 3.2 was foamed by the Milcer method.
Milser method conditions Equipment used: TML24 mill & mixer (TESCOM)
Capacity: 180 mL cup Test solution volume: 50 g
Stirring time: 10 seconds Solution temperature: 25 ° C
4). Fill the 200 mL graduated cylinder with the foamed 3 solution, measure the amount of foam after 0, 5, 10, 20, and 30 minutes, the amount of liquid layer, and foam after 5 and 30 minutes. The fineness was visually observed.

<Evaluation method>
Retention rate of foam: The amount of foam immediately after foaming is defined as 100%, and the retention rate over time of the amount of foam (excluding the liquid layer) is shown.
Foam fineness: The fineness of the foam is visually evaluated on a five-point scale. The fine one is 5 and the coarse one is 1.

  The amount of foam (Table 8), liquid layer amount (Table 9), foam retention (Table 10), and foam when fermented cellulose (Trial 1) or CMC (Trial 2) is added to various cleaning agents, etc. The evaluation result about the fineness of the texture (Table 11) is shown.

  From the above results, by adding fermented cellulose (Trial 1) to the cleaning agent, etc., the amount of foam at the time of foaming increases, the amount of liquid layer generated over time is suppressed, and as a result, foam retention It became clear that the rate improved. In addition, the fineness of the generated foam has been improved, and it has been clarified that it greatly contributes to improving the feeling of use of the cleaning agent and the like.

  When confirmed individually, when fermented cellulose (Trial 1) was added to the body soap, the amount of foam increased significantly compared to no addition or CMC (Trial 2). The amount of the liquid layer generated by the foam repelling is suppressed accordingly, and the retention rate of the foam is also high. Therefore, it is presumed that the effect of keeping the foam on the body surface for a long time is improved. Further, the texture of the generated foam is remarkably fine, and a smooth feeling of use can be provided.

  Next, when fermented cellulose (Trial 1) was added to the laundry detergent, the amount of foam was slightly higher than that of the blank and CMC (Trial 2) added products, but the amount of the liquid layer was significantly lower, and the amount of foam was further reduced. Since the retention rate is also high, it is estimated that most of the added detergent becomes foam and is used for washing. That is, since the detergent to be used can be used without surplus, the amount of detergent can be reduced. Since the fineness of the foam is the same as that of the blank product and the product added with CMC (Trial 2) and is very fine, superiority by adding fermented cellulose (Trial 1) was recognized.

  For the hair color, the amount of foam produced by adding fermented cellulose (Trial 1) was not significantly different from that of the blank product, but no liquid layer was formed and the foam retention rate was high. This means that “liquid dripping” which is a problem when using hair color does not occur. In addition, since the fineness of the foam is the same as the fermented cellulose (Trial 1) additive, the blank product, and the familiarity with the hair is not inferior to the existing product, but there is no dripping, so it feels great. Improved.

表１３に示した結果より、発酵セルロースを使用した実施例１及び２の洗浄剤から生じる泡は、付着面に対しきめ細かな泡が適度に広がって付着し、他品に比べて顕著な付着滞留性を有していた。
一方、発酵セルロース以外の多糖類を使用した比較例品より生じる泡は、きめの細かさに欠け（比較例２、３、５、７）、或いは十分な付着滞留性を示さなかった（比較例２〜７、９）。比較例１及び８では、一部にゲルを生じていたため、噴出時にスプレーのノズルが詰まる場合や、噴出が不十分でノズルから洗浄液が垂れることがあり、十分な噴出を得ることができず上記評価をすることができなかった。 About adhesion retention, spray agent is sprayed on the vertically leaning acrylic panel using a spray container (type that injects foam) until the foam or detergent solution adhering to the wall falls down to the lower end of the acrylic panel. Time was measured. The measurement was performed by spraying with a spray container at a sample temperature of 20 ° C. from a position 15 cm away from the acrylic panel so that a point 22 cm from the lower end of the acrylic panel becomes the center of spraying. The time until dripping was measured three times, and the average was calculated. Table 13 shows the time required for the measured drop.

<Result>
From the results shown in Table 13, the foam generated from the cleaning agents of Examples 1 and 2 using fermented cellulose adhered to the attached surface with fine bubbles moderately spread out, and noticeable adhesion retention compared to other products. Had sex.
On the other hand, the foam produced from the comparative product using polysaccharides other than fermented cellulose lacks fineness (Comparative Examples 2, 3, 5, 7), or did not show sufficient adhesion retention (Comparative Example). 2-7, 9). In Comparative Examples 1 and 8, since gel was partially formed, the spray nozzle was clogged at the time of jetting, or the jetting was insufficient and the cleaning liquid might drip from the nozzle, and sufficient jetting could not be obtained. The evaluation could not be done.

Further, a mixture of 3-methyl-3methoxybutanol, polyoxyethylene (addition mole number 14 moles) tridecyl ether, and monoethanolamine was added with stirring, and the mixture was stirred for 5 minutes to obtain a ventilation fan cleaning agent.

<Preparation method of fermented cellulose 0.3% additive>
An activated 0.6% fermented cellulose aqueous solution was prepared in the same manner as in Test 1, 50 g of the solution was measured, and 38 g of ion-exchanged water was added thereto and stirred. Further, a mixture of 3-methyl-3methoxybutanol, polyoxyethylene (addition mole number 14 moles) tridecyl ether, and monoethanolamine was added with stirring, and the mixture was stirred for 5 minutes to obtain a ventilation fan cleaning agent.

<Evaluation method>
With the same method and evaluation criteria as in Example 1, the effect of improving the retention of bubbles (the amount of bubbles (Table 14), the amount of liquid layer (Table 15), the retention rate (Table 16)) was evaluated. In addition, by filling each trigger spray container with each cleaning agent, spraying it from a distance of 10 cm toward the vertically standing acrylic panel, and measuring the time that the generated foam and liquid dripping down to the lower end of the acrylic panel The effect of suppressing the falling of bubbles was evaluated. The center of spraying was 22 cm from the lower end of the acrylic panel, the time required for dripping down to the lower end was measured three times, and the average value was calculated. The results are shown in Table 17.

From the results of Tables 14 to 17, it was clarified that by adding fermented cellulose to the cleaning agent for a ventilation fan, the cleaning agent had good foam retention and foam falling was suppressed. From this, it has been clarified that when a cleaning agent for a ventilation fan to which fermented cellulose is added is sprayed on the ventilation fan, foam adheres to the ventilation fan for a long time and a sufficient cleaning effect can be expected.
