JP6639808B2 - Foam stabilizer and cleaning agent using the same - Google Patents

Description

The present invention relates to a foam stabilizer and a detergent using the same.

As an example of a foam that generates foam and is used for the purpose of use (hereinafter, referred to as a foam composition), a detergent can be exemplified. A solvent suitable for the object to be cleaned and various components are mixed in the cleaning agent, and a dosage form is taken in consideration of convenience during use.

 Chelating agents, dispersants, surfactants, soaps, polysaccharides, and the like are added to the detergent. The main purpose of the cleaning agent for removing dirt from the object is mainly due to the surfactant. The surfactant is adsorbed on the dirt and the dirt is separated from the dirt, thereby cleaning the dirt. At the time of washing, bubbles are generated by the components contained in the cleaning agent. The bubbles prevent separated dirt from re-adhering to the target object, and also increase the contact time of the surfactant with the dirt components. The effect is expected.

As a method for improving the foaming property, a method using a glyceroglycolipid surfactant has been disclosed (Patent Document 1). However, since excessive use of the surfactant has an effect on the environment, an alternative technique is required. Have been.

In addition, there are various causes for disrupting the texture of the skin, one of which is excess keratin or sebum in the skin.
As means for removing such dirt such as stratum corneum and sebum, attempts have been made to remove by adsorption using powder. For example, a scrub cosmetic containing a water-soluble polymer, water-insoluble granules, and a carbonic acid diester compound (for example, see Patent Document 2), a skin cleanser containing hydroxyapatite and an amino acid-based surfactant (for example, see Patent Reference 3), skin cosmetics containing a water-swellable clay mineral, a polyhydric alcohol and a nonionic surfactant (for example, see Patent Reference 4) have been proposed.

  However, although dirt such as keratin and sebum can be removed by these attempts, the above-mentioned ones are intensely irritating to the skin, and thus have insufficient action to adjust the texture of the skin after use.

Furthermore, the above-mentioned Nadesicoceae (Dianthus) is particularly preferable to D. superbus L. var. Longicalycinus, and can obtain a higher concentration of the active ingredient.

In the present invention, the site is not particularly limited. For example, fruits, seeds, leaves and the like can be used, but it is preferable to use seeds.

There is no particular limitation on the method of obtaining the extract from the above-mentioned Kawaraneshiko (D. superbus L. var. Longicalycinus), and examples thereof include polar solvent extraction and supercritical extraction. Note that either one of these may be performed, or both may be performed. This extraction may be performed only once for each method, or may be performed twice or more.

Here, in the case of extracting by polar solvent extraction, the polar solvent to be used is not particularly limited. For example, water, methanol, ethanol, isopropanol, acetone, 1,3-butylene glycol, ethylene glycol, propylene glycol, 1,3 -Alcohols and polyhydric alcohols such as propanediol and glycerin, and acetic acid, ethyl acetate, ether and the like. Of these, water and alcohols are preferred. At this time, the alcohol is preferably methanol, ethanol, 1,3-butylene glycol, propylene glycol, or 1,3-propanediol. This is because the active ingredient can be efficiently extracted. These may be used alone or in combination of two or more.

When water is used as the polar solvent, the extraction may be performed at a temperature of 20 to 100 ° C, preferably about 40 to 70 ° C. This is because if the extraction temperature is too low, it is difficult to extract the active ingredient. The type of water for extraction is not particularly limited, and tap water, distilled water, mineral water, alkaline ionized water, and the like can be used.

When using a hydroalcoholic alcohol as the polar solvent, the alcohol concentration is preferably at least 10 wt%, more preferably at least 30 wt%. This is so that a high extraction amount of the active ingredient can be obtained. Further, the extraction temperature is preferably 0 to 95 ° C., preferably about 20 to 80 ° C. The aqueous alcohol extraction may be repeated at various concentrations in order to improve the content of the active ingredient.

  In the case of extracting with a polar solvent, the extraction method is not particularly limited, and for example, any method such as continuous extraction, immersion extraction, and countercurrent extraction can be employed. Can be used. When the extraction is performed by the above-described method, only one of them may be performed, or these methods may be combined. These extractions may be performed only once, or may be performed two or more times.

As a specific method, a raw material for extraction (seed of Kawaranadeshiko) is charged into a treatment tank filled with an extraction solvent, and the active ingredient is eluted with stirring. For example, when water or water-containing alcohol is used as the extraction solvent, the extraction is performed for about 1 minute to 150 hours using a polar solvent of about 5 to 100 times (weight ratio) the extraction raw material. After the active ingredient is eluted in the solvent, the extract is obtained by filtering to remove the extraction residue. Thereafter, the extract is subjected to treatments such as dilution, concentration, drying and purification according to a conventional method to obtain an extract containing a high concentration of the active ingredient.
Examples of the purification method include activated carbon treatment, resin adsorption treatment, ion exchange resin, liquid-liquid countercurrent distribution, and membrane separation.

Further, when extraction is performed by supercritical extraction, the supercritical fluid used at this time is not particularly limited, and examples thereof include carbon dioxide and nitrogen. These may be used alone or in combination of two or more. Of these, carbon dioxide is particularly preferred.
This is because the active ingredient can be more easily extracted. The extraction method at this time may be performed by a known method. Thereafter, the extract is subjected to treatments such as dilution, concentration, drying and purification according to a conventional method to obtain an extract containing a high concentration of the active ingredient.

  The foam composition according to the present invention is characterized by containing a surfactant and the above-mentioned Nadesico family (Dianthus) used as a foam stabilizer or the like and / or an extract thereof.

The surfactant is not particularly limited, and includes, for example, soaps such as sodium soap, potassium soap, ammonium soap, amino acid soap, complex soap, and the like;
Anionic surfactants (linear alkyl benzene sulfonate, alkyl sulfate, α-olefin sulfonate, ether sulfate, alkyl phenyl polyethylene glycol ether, alkyl polyethylene glycol ether, etc.), nonionic surfactant (polyoxyethylene Alkyl ethers, fatty acid alkanolamides, alkyl polyglucosides, etc., cationic surfactants (di-long-chain alkyl quaternary ammonium salts, mono-long-chain alkyl quaternary ammonium salts, etc.), amphoteric surfactants (alkyldimethylaminoacetic acid) Surfactants such as betaine and fatty acid amidopropyl betaine; and the like.

Further, the foam composition of the present invention may further contain the following components, if necessary, in addition to the foam stability and the like and the surfactant.
Inorganic builders (various zeolites, amorphous aluminosilicates, sodium pyrophosphate, sodium carbonate, crystalline sodium silicate, sodium sulfate, sodium tripolyphosphate, etc.), organic builders (aminocarboxylate, hydroxyaminocarboxylate, hydroxycarboxy) Detergency aids such as acid salts, cyclocarboxylates, ether carboxylate, organic carboxylate polymers, etc.);
Alkaline agents such as carbonates, silicates, phosphates, borates and amines; enzyme agents such as proteases, lipases and amylases;
An anti-redeposition agent such as carboxymethylcellulose (CMC) and polyethylene glycol;
Other bleaching agents, softening agents, foam control agents, fluorescent whitening agents, reducing agents, fragrances, dyes, antibacterial agents, etc.

In addition, gum arabic, locust bean gum, xanthan gum, karaya gum, tragacanth gum, gutti gum, alginic acid and salts thereof, starch, hyaluronic acid, pectin, gellan gum, karaya gum, water-soluble hemicellulose, hinder the effect of the present invention, Those used for the foam composition can be used in any combination as long as they do not exist.

The Nadesico family Nadesico (Dianthus) and / or its extract improve the foam stability of the surfactant by blending with the surfactant, and also has the effect of improving the foaming power of the surfactant. Have. Thereby, the above-mentioned Nadesico family (Dianthus) and / or an extract thereof can be used as an excellent foam stabilizer and foaming power improver.
Therefore, the foam composition of the present invention allows the foam to sufficiently contact the soiled portion of the object by keeping the foam without disappearing and remaining for a long time. As a result, a surfactant or a component having an antibacterial / bactericidal effect contained in the foam composition comes into contact with the soiled portion for a long time, and the effect is maximized. Thereby, even if the amount of the foam composition is small, it is possible to enjoy a sufficient cleaning effect, and it is possible to improve the residual detergent and the residual soap. Thereby, the above-mentioned Nadesicidae family (Dianthus) and / or its extract can be used as an excellent cleaning aid, and the foam composition provides a cleaning agent having a more excellent cleaning action. Can be.

When the foam composition of the present invention is used as a detergent, it is, for example, a detergent for the body or a detergent for the home, and specifically, a shampoo for the hair and the body, a body surface such as a face wash or a hand soap. It can be used for cleaning, and is not limited to cleaning agents used for bathrooms such as floors and walls of houses, windows, bathtubs, washrooms, toilets, and the like.

In addition, the foam composition targeted in the present invention, besides the cleaning agent, such as a hair color and a polishing agent for automobile tires, may be exemplified without limitation those provided for the purpose of use by generating foam. it can. Or hair color, cosmetics, shaving foam, bath foaming agent (bubble bath), hair remover, hair restorer, insecticide, bleach, fire extinguisher, ornamental fish bait, horticultural fertilizer, automobile used for gray hair or hair dyeing Polishes for tires and leather shoes. In addition, other than the above-described cleaning agents, the technology of the present invention can be used as long as the composition is a foam composition that utilizes many foams.

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

The fire extinguishing agent covers the source of the fire with foam over a wide area for a long time, thereby shutting off the supply of oxygen and leading to fire suppression. By making the bait for the aquarium fish into a foam, the aquarium fish ingests the foam floating on the water surface, and the visibility is improved due to the ease of feeding and the strange appearance. By making the horticultural fertilizer foamy, the effect that the fertilizer component gradually permeates over a long time can be expected. Since the appearance is foam, it is considered to contribute to aesthetics. Further, in the case of a polishing agent for automobile tires, fine bubbles are uniformly adhered to the tire surface for a long time, so that the tire can be polished without coating unevenness.

You can see that On the other hand, as shown in FIG. 4, it can be seen that the bubbles of Sample 4 remain without disappearing even after 30 seconds have elapsed (arrows in FIG. 4). In addition, in Sample 4, it was confirmed that bubbles were generated for 7 minutes or more after stirring. From this, it was confirmed that foam stability was improved by blending the extract of Kawaranadeshiko with amino soap which is a surfactant.

Test Example 2: Evaluation of the foaming power-improving action and foam stability of the extract of Kawaranesico was evaluated using the apparatus shown in FIG.
In FIG. 5, 10 mL of each sample shown in Table 2 below was placed in cylinder B, and 40 mL of the same sample was placed in cylinder A. Thereafter, the cock of the cylinder A was opened, and the sample was allowed to flow at a flow rate of about 0.8 mL / sec. Then, the height of the foam immediately after the completion of the flow of the liquid (foaming force improving effect) and the height of the foam 5 minutes and 30 minutes after the completion of the flow (foam stability) were measured. In this case, the height of the foam was an average of the highest portion and the lowest portion. FIG. 6 shows the result. “Amino Soap” in Table 2 below is Amino Soap® AR-12 (30.0% of coconut oil fatty acid arginine, 0.2% of potassium hydroxide, 69.8% of water) manufactured by Ajinomoto Healthy Supply Co., Ltd.

Results and Effect of Example in Test Example 2 As shown in FIG. 6, immediately after the end of the flow, Sample 3 in which the extract of Kawaranadeshico was blended had the highest foam height. Thus, it was confirmed that the foaming power was improved by blending the extract of Kawaranadeshiko with amino soap, which is a surfactant. Samples 1 and 2 showed a sharp decrease in foam height over time, whereas Sample 3 showed only a gradual decrease in foam height. It was confirmed that the height was large. Thus, it was confirmed that foam stability was improved by blending the extract of Kawaranadeshiko with amino soap, which is a surfactant.

Test Example 3: Detergency-Improving Action of Kawanadesico Extract The detergency-improving action of Kawanadesico extract was evaluated by the following method.
Test Example 3-1: Test with back of hand
1. Marking was made on the test point on the back of the hand (Fig. 7).
2. The same amount of activated carbon was applied to hands by puff.
3. In the control, sample 1 in Table 3 below and sample 2 containing the extract of Kawaranesico, rub each in a circular motion 20 times, rinse with water, gently wipe off the water with a puff, and wash with a microscope. The degree was observed.
4. The above-mentioned 3 was repeated three times. Photos were taken before, immediately after, and after washing. FIG. 8 shows the result. In addition, "Amino soap" of the following Table 3 is amino soap (registered trademark) AR-12 (30.0% of coconut oil fatty acid arginine, 0.2% of potassium hydroxide, 69.8% of water) manufactured by Ajinomoto Healthy Supply Co., Ltd.

Test Example 3-2: Test Using Arm The same method as in Test Example 3-1 was performed using an arm. FIG. 9 shows the result.

Results and Effect of Example in Test Example 3 As shown in FIGS. 8 and 9, the sample 1 (control) in which the extract of Kawaranadeshiko in Table 3 above was not blended had activated carbon particles even after washing three times. While a large amount remains,
In the third battlefield, it was confirmed that the activated carbon particles were substantially removed from the amino soap containing the extract of Kawanadeshiko of Sample 2 in Table 3 above. From the above, it can be seen that the addition of the extract of C. elegans improves the cleaning ability of the surfactant.

Test Example 4: Evaluation of the texture improving effect of the extract of Kawaraneshiko
The subjects were 14 males and females (9 males and 5 females) between the ages of 23 and 61. Subjects applied a lotion containing about 1 mL of the above-mentioned Nadesico extract 5% twice daily to the whole face after washing their face in the morning and evening, and the skin texture values before application and 8 weeks after the start of application were measured using RoboSkin Analyzer CS50 (trade name). Infoword). The measurement was performed after acclimation for 15 minutes in a room adjusted to a room temperature of 21 ± 3 ° C. and a humidity of 43 ± 3%, and application was performed for 8 weeks. Here, "texture value" was defined and detected as follows. That is, in a monochrome image created using the BLUE signal of the RoboSkin Analyzer CS50, the dark part is a skin groove, the bright part is a skin hill, and the dark part and the light part are emphasized by a computer, and the result of binarization is obtained. The case where a regular triangle having a side of 0.4 mm was formed was defined as a texture value 100 indicating good texture, and the closer the value was, the higher the score out of 100 points of the texture value was calculated and calculated. At this time, the condition of the skin under the left cheek was observed. Table 4 shows the results.

According to Table 4, the improving effect on the texture was confirmed in 10 out of 14 subjects (71%). This confirmed that the Kawanadeshiko extract was useful as a texture improver.

  As described above, the present invention provides a foaming power improver, a foam stabilizer, a cleaning accelerator and a skin texture improver containing a novel component as an active ingredient, and a cleansing agent and a skin external preparation using the same. Can be provided.
