Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shampoo composition, and more particularly, to a hypoallergenic shampoo which has an excellent effect of preventing fading of hair color, foams, passes through fingers during shampooing, and has excellent smoothness during rinsing. Composition.

[0002]

2. Description of the Related Art In general shampoo compositions, polyoxyethylene alkyl ether sulfate or alkyl sulfate is used as a main agent, and foaming is excellent in finger washing during hair washing. Discoloration was a problem when used. In addition, skin problems are a problem in the case of a hairdresser who has skin irritation and has many shampoos in his occupation or has sensitive skin.

[0003] Hypoallergenic shampoo compositions include N
-Acylglutamate, N-acylmethyltaurate, sulfosuccinate, amidopropylbetaine salt, imidazolinium betaine salt and the like are used as main agents. However, although these surfactants are hypoallergenic, they did not solve the fading when used for hair coloring hair.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the problems of the shampoo composition described above, is excellent in the effect of preventing fading of hair color, foams, passes through fingers during washing, and has excellent smoothness during rinsing. It is intended to provide an irritating shampoo composition.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above problems, and as a result, have combined (A) an alkyl ether acetate and (B) a sucrose fatty acid ester, and By containing (C) a protein type surfactant and / or (D) an amino acid type surfactant and (E) a cationic polymer, the effect of preventing fading of hair color is excellent, foaming, finger washing during rinsing, and rinsing. The present inventors have discovered that a shampoo composition having low irritation with excellent smoothness can be obtained, and the present invention has been completed.

That is, by combining (A) an alkyl ether acetate and (B) a sucrose fatty acid ester, the foaming and detergency required for a shampoo composition and the effect of preventing fading of hair color are exhibited. Further, by containing (C) a protein type surfactant and / or (D) an amino acid type surfactant and (E) a cationic polymer, smoothness during finger washing and rinsing can be improved. is there.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The alkyl ether acetate (A) used in the shampoo composition of the present invention includes, for example, sodium polyoxyethylene lauryl ether acetate and sodium polyoxyethylene tridecyl ether acetate.

The (B) sucrose fatty acid ester used in the shampoo composition of the present invention includes, for example, sucrose laurate, sucrose palmitate, sucrose stearate, and sucrose oleate. .

[0009] The total content of (A) and (B) in the shampoo composition of the present invention is 1 to 50% by weight, preferably 5% by weight.
４０40% by weight. If the amount is less than 1% by weight, sufficient foaming and detergency cannot be obtained. The mixing ratio of (A) and (B) is (A)
/ (B) = 50/1 to 1/10 (weight ratio) is preferred.
When the proportion of (A) is larger than this range, a sufficient effect of preventing fading of the hair color cannot be obtained.

[0010] The (C) protein type surfactant used in the shampoo composition of the present invention includes, for example, coconut oil fatty acid hydrolyzed collagen sodium, coconut oil fatty acid hydrolyzed collagen potassium, coconut oil fatty acid hydrolyzed collagen triethanolamine, lauroyl. Hydrolyzed silk sodium and the like.

Examples of the (D) amino acid type surfactant used in the shampoo composition of the present invention include N-coconut fatty acid acylglycine triethanolamine, N-
Coconut oil fatty acyl-DL-alanine triethanolamine, N-lauroyl-N-methyl-β-alanine triethanolamine, lauroyl sarcosine triethanolamine, N-coconut fatty acid acyl-L-aspartate triethanolamine, N- Palm oil fatty acid acyl-L
-Triethanolamine glutamate, sodium N-coconut fatty acid acyl-L-glutamate, potassium N-coconut fatty acid acyl-L-glutamate and the like.

(C) in the shampoo composition of the present invention
And / or the total content of (D) is 0.1 to 30% by weight, preferably 1 to 20% by weight. If the amount is less than 0.1% by weight, sufficient finger passing at the time of washing the hair cannot be obtained.

The (E) cationic polymer used in the shampoo composition of the present invention includes, for example, cationized cellulose, cationized guar gum, dimethyldiallylammonium chloride / acrylamide copolymer, cationized collagen, cationized keratin and the like. Is mentioned. (E) The content of the shampoo composition of the cationic polymer is 0.01 to 5% by weight, preferably 0.1 to 2% by weight.
% By weight is desirable. If it is less than 0.01% by weight, sufficient smoothness at the time of rinsing cannot be obtained, and if it exceeds 5% by weight, the viscosity increases and the feeling in use is remarkably reduced.

In the shampoo composition of the present invention, in addition to the above essential components, other components can be appropriately compounded within a range not to impair the effects of the present invention. For example, anionic surfactants such as polyoxyethylene alkyl ether sulfates, alkyl sulfates, and sulfosuccinates; amphoteric surfactants such as amidopropyl betaine salts and imidazolinium betaine salts; and nonionic surfactants such as polyoxyethylene alkyl ethers Surfactants, cationic surfactants such as lauryltrimethylammonium chloride, stearyltrimethylammonium chloride, oils such as hydrocarbons, ester oils, animal and vegetable oils, silicone derivatives, protein derivatives,
Conditioning agents such as polyhydric alcohols, thickeners such as hydroxyethylcellulose, antidandruff agents, anti-inflammatory agents, antioxidants, chelating agents, ultraviolet absorbers, preservatives,
A pH adjuster, a pearlescent agent, a pigment, a fragrance, and the like can be added as necessary.
