Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid cleaning agent composition for residential use, which has excellent cleaning power especially against stubborn oil stains adhering to kitchens, etc., and stains adhering to bathrooms and toilets. This invention relates to an all-purpose liquid cleaning composition.

Liquid detergents used for removing oil stains from kitchens, etc., are blended with surfactant and alkali, as described in JP-A-54-1584O8, and monoethylene glycol or diethylene glycol monomers are used as a solvent. Conventionally, compounds containing alkyl ethers and the like have been known. However, although it has excellent cleaning power for oil stains, it has the disadvantage that it does not have a satisfactory cleaning power for bathroom scale stains and the like.

The inventors of the present invention have conducted extensive research in order to develop an all-purpose liquid cleaning composition that is solvent-based and has excellent oil stain cleaning power and is also effective in cleaning bathroom scale stains. As a result, the present invention was completed. That is, the present invention provides a surfactant with the general formula [
They discovered that a detergent suitable for the intended purpose could be obtained by blending the compound represented by T) and further blending a detergency auxiliary agent, and completed the present invention. The present invention also provides the following: (A) 0.1 to 20 wt% of one or more surfactants (B) Solvents 1 to 20% by weight represented by the following general formula (I) 20%
+1% RO [(C2H4O)m (CaHsO)n) R'
(T) In the formula, when either m or n is 0, R and R' are an alkyl group having 1 to 4 carbon atoms, and m, n>
When O, R and R' are H or an alkyl group having 1 to 4 carbon atoms, and neither R nor R' is H. However, m and n are 0 to 4, and m + n = 1 to 6. Also, the number in parentheses is a polyoxyalkylene chain in which oxyethylene groups and oxypropylene groups are bonded randomly and/or in blocks.

(C) 0.1 to 15% by volume of one or more alkaline substances selected from organic amines such as alkanolamines and/or caustic alkalis; (D)) A liquid cleaning agent containing water balance.

The surfactant which is component (A) in the present invention is not particularly limited as long as it can promote wetting of dirt and emulsifying and dispersing action.

Any of various anionic, nonionic and amphoteric surfactants can be used. Typical examples of surfactants that can be used as component (A) are listed below: (a) Anionic surfactant (1) Sulfonate linear or branched alkyl (C, ~2□) benzenesulfonate; Long chain alkyl (C, ~2□) sulfonate, etc. (2) Sulfate long chain monoalkyl (cm ~22) sulfate ester salt, polyoxyethylene (1 to 6 moles) long chain alkyl (Cs""
-a□) Ether sulfate salt, polyoxyethylene (1 to 6 mol) alkyl (cg to 18.) phenyl-thyl sulfate salt, etc. (3) Carboxylate system with an average carbon number of 10 to 24, saturated or unsaturated fatty acid salts, etc., (4) phosphate long-chain monoalkyl, dialkyl or sesquialkyl (C
S-2□) Phosphate, polyoxyethylene (1 to 6 mol) Monoalkyl, dialkyl or sesquialkyl (CS
-22) Phosphates, etc. However, the counter ions (cations) of each of the above anionic surfactants are sodium, potassium,
It may be any of alkali metal or alkaline earth metal ions such as magnesium, and alkanolamine ions such as monoethanolamine, jetanolamine, and triethanolamine.

(b) Nonionic surfactant polyoxyethylene (1 to 20 mol) long chain alkyl (C
O-22) ether, polyoxyethylene (1-20 mol) alkyl (CS-, 8) phenyl ether, polyoxyethylene polyoxypropylene block polymer,
Higher fatty acid alkanolamide or its alkylene oxide adduct, long chain tertiary amine oxide (C12-1
4) etc. (c) Amphoteric surfactant Amino acid type amphoteric surfactant, alkyl sulfobetaine,
Betaine type amphoteric surfactants such as alkyl acetic acid betaine, imidacilline type amphoteric surfactants, etc. Each surfactant including the typical examples exemplified above can be used alone as component (A). ,
Component (A) can also be a combination of two or more types. The amount of surfactant added is 0.1 to 20 wt% of the cleaning composition.
, preferably in the range of 1 to 10 wt%. This amount is 0
．． If the surfactant is less than 1 wt%, the emulsifying and dispersing effect and solubilizing effect of the surfactant will not be sufficient. On the other hand, if the surfactant is blended in an amount exceeding 20 wt%, no particular improvement in detergency can be expected; This is undesirable because it causes bubbles to run out and the rinsability to deteriorate.

Component (B) of the present invention is a component that has excellent detergency against denatured oil stains and also has excellent detergency against hot water scale stains, etc.
It is a solvent represented by the following general formula (1).

ROI: (C2H4O)m (C3H,0)n) R'
CI) In the formula, when either m or n is 0, R
and R' are an alkyl group having 1 to 4 carbon atoms, and m,
n) When O, R and R' are H or an alkyl group having 1 to 4 carbon atoms, and neither R nor R' is H. However, m and n are O to 4, and m + n = 1 to 6. Also, the number in parentheses is a polyoxyalkylene chain in which oxyethylene groups and oxypropylene groups are bonded randomly and/or in blocks.

Examples of solvents that can be used for component (B) represented by the above general formula are ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, hexaethylene glycol dimethyl ether, diethylene glycol methyl ethyl ether, triethylene glycol methyl ethyl ether, diethylene glycol methyl Butyl ether, triethylene glycol methyl butyl ether, diethylene glycol diethyl ether, C1,0(EO)3(P
O) H1C2H, O(EO), (PO). ,6H,C
4) 170 (EO) 3 (PO). , 6H, CH30(E
O)3(PO)12C2H5 and the like.

The blending amount of this (R) component is in the range of 1 to 20 wt%, preferably 3 to 15% it. If this amount is less than 1wt%, the effect of dissolving denatured oil and scale is poor;
If the amount exceeds %, the solvent odor will be strong and the storage stability will be insufficient.

Component (C) of the present invention is a component that synergistically improves the cleaning effect of component (B). Component (C) includes organic amines such as aliphatic amines, morpholine, ammonia, monoethanolamine, jetanolamine, and triethanolamine, and/or alkaline substances such as caustic soda and caustic potash. The blending amount is 0.1-15wt%
, preferably 0.5 to 10 wt%, and this amount is 0.5 to 10 wt%.
If it is less than 1 wt%, the ability to saponify and remove denatured oil is weak (,1
Even when the amount exceeds 5 wt%, no significant improvement in effect is observed.

The structure and effects of the present invention will be explained in more detail using Examples, but prior to that, a method for evaluating the cleaning agent in Examples will be described below.

1) Cleaning power for oil- and fat-denatured stains (i) Type of stain 1 After heating salad oil at high temperature for a long time to make it viscous and applying it to the plywood and leaving it indoors for a long time, the oil becomes yellowish brown and resinous. The resulting material was used as a dirt board. After applying the liquid detergent, a load of 500 g was applied to the cotton knitted cloth and the cloth was reciprocated 10 times, and the state of the stain was visually judged according to the following criteria.

5 points: Good dirt removal 4 points: Stain removal is somewhat good 3 points: Stain removal is uneven 2 points: Slight removal of dirt 1 point: Dirt is hardly removed (minus) Type of dirt 2: Apply a mixture of vegetable oil and carbon black in a weight ratio of 100/2 evenly to the iron plate, and then
A stain board was obtained by firing at a temperature of 0 to 200°C for 40 to 60 minutes. After applying a liquid detergent to this, a load of 500 g was applied to the cotton knitted cloth and the cloth was made to reciprocate 10 times, and the state of dirt was visually judged according to the following criteria.

5 points: Good dirt removal 4 points: Stain removal is somewhat good 3 points: Stain removal is uneven 2 points: Slight removal of dirt 1 point: Dirt is hardly removed 2) Hot water scale Cleaning power for stains Sprinkle the cleaning solution (undiluted solution) on the scale stains (used for one month) on the bath tub (made of polypropylene) that cannot be easily removed by rubbing, and wipe the surface of the tub with a sponge (urethane foam) with a load of approximately 500 g. (manufactured by KOKUYO Co., Ltd.) to visually judge the state of dirt removal.
