Abstract

PURPOSE:To obtain a skin detergent composition excellent in detergency, foaming properties and feeling of use and further finish properties by blending a polyoxypropylene adduct of diglycerol with other ingredients. CONSTITUTION:This skin detergent composition is obtained by blending one or two or more polyoxypropylene adducts of diglycerol with a skin detergent composition containing a higher fatty acid soap or a nonsoapy synthetic detergent such as an alkylene oxide adduct-sulfuric acid ester salt as a principal detergent active ingredient. Thereby, the detergency is good and fine and creamy foaming properties are obtained. Furthermore, this composition is good in rinsing properties after washing and excellent in finish properties without any remaining tenseness, dryness, etc., after drying at all and waxy feeling.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a body shampoo,
The present invention relates to a skin cleansing composition for use on the body, such as a face wash.

[0002]

2. Description of the Related Art If you wash your skin with soap or synthetic detergent to cleanse the skin, the moisture and fat that give the skin's stratum corneum are washed away more than necessary. Problems such as a feeling of tightness occur. Therefore, conventionally, wetting agents such as water-soluble silicone derivatives, water-soluble glyceride derivatives, glycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol, and oil agents such as hydrocarbon oils, higher alcohols, and animal and vegetable oils are used for skin. By adding it to the cleaning agent, we are trying to solve such a problem.

[0003]

However, the above-mentioned additives do not always exhibit sufficient effects. That is, most of water-soluble silicone and glyceride derivatives and wetting agents such as glycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol are washed away with water by rinsing at the time of washing, and the effect is not sufficiently exerted. . Further, by adding an oil agent such as a hydrocarbon oil, a higher alcohol, or an animal or vegetable oil or fat, there is a problem that the rinsing property at the time of cleaning is deteriorated and a slimy feeling remains.

[0004]

In view of such circumstances, the present inventors have conducted intensive studies to solve the above-mentioned drawbacks, and as a result, added propylene oxide to diglycerin which is a water-soluble polyhydric alcohol. By expressing the oily feeling,
By blending a specific compound in the skin cleansing composition, good detergency, fine and creamy foaming property can be obtained, and further, rinsability after washing is good and there is no slimy feeling, and tautness is obtained after drying. The inventors have found that a skin cleansing composition having excellent finishing properties, which does not leave any feeling of feeling or bulkiness, is obtained, and completed the present invention.

That is, the present invention is characterized by blending a polyoxypropylene adduct of diglycerin, and has good detergency, fine and creamy foamability, and good rinsability after decontamination. The present invention relates to a skin cleansing composition which has no slimy feel and leaves no feeling of tightness or bulkiness after drying and has excellent finish.

The structure of the present invention will be described in detail below. As the cleaning active principal component used in the present invention, a non-soap synthetic detergent such as higher fatty acid soap or alkylene oxide addition sulfate ester salt can be used. When the higher fatty acid soap is the main component, examples of the cleaning active main component include alkali metal salts of higher fatty acids having 8 to 22 carbon atoms, organic amine salts, and the like. The higher fatty acid may be a saturated fatty acid or an unsaturated fatty acid, and a linear saturated fatty acid having 10 to 18 carbon atoms is particularly preferable. Examples of the salt include alkali metal salts such as lithium salt, potassium salt and sodium salt, mono-, di-, and trialkanolamine salts having an alkyl group having 2 to 4 carbon atoms. Specific examples thereof include lithium salts such as single fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, coconut oil fatty acids, mixed fatty acids such as tallow fatty acids, potassium salts, sodium salts, trialkanolamine salts and the like. Can be mentioned. These soaps may be used alone or in combination of two or more, and the compounding amount thereof is selected in the range of 3 to 30% by weight, preferably 8 to 25% by weight of the composition.

The method for preparing the detergent composition is not particularly limited, and it can be prepared in a liquid or cream form according to a commonly used method. At this time, various cleaning active ingredients can be blended, if necessary, within a range not impairing the present invention. As its components, polyoxyethylene fatty acid ester, polyoxyethylene alkyl ether, alkylallyl polyoxyethylene ether, alkylol amide, alkyl glycerine ether type polyoxyethylene ether, sucrose fatty acid ester, polyoxyethylene fatty acid amide, polyoxy Examples thereof include nonionic surfactants such as ethylene alkylamine and alkyl glucode, and amphoteric surfactants such as alkyl betaine type, amido betaine type and imidazoline type. These components may be used alone or in combination of two or more.

Examples of the detergent active ingredient used when the main component is a non-soap synthetic detergent include anionic surfactants, sulfosuccinates, amphoteric surfactants, nonionic surfactants, and the like. A combination of two or more is preferable. Examples of the anionic surfactant include alkyl sulfates, polyoxyethylene alkyl ether sulfates, alkyl amide sulfates, alkyl phosphates, alkyl amide phosphates, polyoxyethylene alkyl ether phosphates, and alkyloyl alkyl taurine salts. , N-long chain acyl amino acid salts and the like, and examples of the sulfosuccinate include:
Examples thereof include oleic acid amide sulfosuccinate, polyoxyethylene sulfosuccinate, alkyl sulfosuccinate, and polyoxyethylene alkyloyl ethanolamide sulfosuccinate. As the nonionic surfactant and the amphoteric surfactant, those mentioned above can be mentioned.
The amount of the above-mentioned surfactant compounded is 5 to 5 with respect to the total composition.
It is preferable to add 0% by weight, particularly 10 to 40% by weight. The preparation method is not particularly limited, and it can be prepared in a liquid form or a cream form according to a commonly used method.

The polyoxypropylene adduct of diglycerin used in the present invention can be obtained by addition-polymerizing propylene oxide to diglycerin by a conventional method. The characteristic of the polyoxypropylene adduct of diglycerin is that it is obtained by addition-polymerizing propylene oxide to diglycerin which is a water-soluble polyhydric alcohol.
It has a moisturizing property, and by gradually increasing the number of moles of polyoxypropylene added to diglycerin, it is possible to obtain a slightly oily to strong oily feeling. The number of moles of propylene oxide added is preferably 4 to 30 moles, and particularly preferably 9 to 20 moles, per 1 molecule of diglycerin. When the number of moles of propylene oxide added is 4 moles or less, the oily feeling is not sufficiently expressed and thus the finishing effect is insufficient, and when it is 30 moles or more, the hydrophobicity becomes strong and it is difficult to mix.

In the present invention, one or more polyoxypropylene adducts of diglycerin are selected and used. The blending amount is optional depending on the finish after washing and drying and is not particularly limited, but it is preferably 1 wt% or more, particularly 3 to 10 wt% with respect to the entire composition.
Further, by using the polyoxypropylene adduct of diglycerin in combination with a usual polyhydric alcohol, it is effective in terms of finish after washing and drying. Among the polyhydric alcohols, the use of diglycerin or polyglycerin is more effective.

The skin cleansing composition of the present invention may contain, if necessary, auxiliary additives which are generally used, as long as the effects of the present invention are not affected. Such auxiliary additives include, for example, sodium chloride, Borate, solubilizers, antioxidants such as dibutylhydroxytoluene and α-tocopherol, ultraviolet absorbers, protein derivatives, animal and plant extracts, bactericides, pigments, fragrances, etc. Can be mentioned.

Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited thereto. Prior to the description, the evaluation method adopted in each example will be described.
