Description

A cleansing composition comprising mild surfactant,

The present invention relates to detergent compositions that are less irritating to the human body, and more particularly to hypoallergenic body cleansing compositions containing alkylpolyglucoside sulfonates and containing cationic polymers.

In general, detergents for human body such as shampoo, body wash, foam cleanser and the like are used for cleaning the body that is stained by sweat or various sebum secreted through human metabolism. Conventional detergents for the human body are typically products in which the surfactant sodium lauryl ether sulfate (SLES) is the main surfactant component.

The detergent composition comprising the conventional SLES surfactant has excellent detergency, but SLES has a disadvantage of severe skin irritation. In addition, the ethylene oxide and sulfate functional groups included in SLES have a problem of generating dioxane which is harmful to human body.

Recently, researches have been actively conducted to develop a detergent containing an hypothetical surfactant such as ethylene oxide free by replacing the SLES surfactant with a detergent for human body.

As an alternative to SLES, for example, alkyl polyglucosides are environmentally friendly and hypoallergenic surfactants, and attempts have been made to develop detergent compositions comprising them. However, the alkylpolyglucoside has a relatively high price in comparison with a surfactant such as SLES, which is conventionally used, and has a problem that it is difficult to commercialize the surfactant because of its poor stability and compatibility when it is formulated into a product.

Accordingly, there is a need to develop a detergent composition containing a hypo-surfactant capable of replacing the SLES surfactant while improving the compatibility of the alkyl polyglucoside.

A problem to be solved by the present invention is to provide a detergent composition containing a cationic polymer and replacing SLES with a surfactant which is less irritating to the human body.

In order to solve the above problems, the present invention provides hypoallergenic human cleanser compositions comprising a cationic polymer comprising alkyl polyglucosides sulfonate.

As a result of intensive research efforts to overcome the problems of the prior art, the present inventors have found that when alkylpolyglucoside sulfonate is used instead of SLES which causes skin irritation as a surfactant in a detergent composition, I also found an amazing fact that it is excellent. Further, the present inventors have found that the addition of an auxiliary surfactant can further increase the stability and cleaning effect, thereby solving the problem that the compatibility of the alkyl polyglucoside sulfonate is poor, thus completing the present invention.

In addition, a cationic polymer is used in the human body detergent composition of the present invention to improve the feeling of use, and the stability of the detergent composition is reduced when the cationic polymer is included. Accordingly, the present invention provides an incredible discovery that the stability of the composition is significantly improved even when containing a cationic polymer when the alkylpolyglucoside sulfonate, preferably alkyl polyglucoside sulfonate, and cosurfactant are contained in the human cleanser composition Thereby completing the present invention.

In the present invention, the alkyl polyglucoside sulfonate means a compound represented by the following general formula (1).

[Chemical Formula 1]

The R ₁ may be an alkyl group of C 8-18, preferably a C 8-14 alkyl group, most preferably a C 10 alkyl group. n represents an average polymerization degree and may be 1 or 2. In the formula (2), R ₁ represents a C 10 alkyl group.

In the present invention, the alkylpolyglucoside sulfonate may be contained in an amount of 0.1 to 10% by weight, preferably 1 to 9% by weight, more preferably 2 to 8% by weight, based on the total weight of the composition. When the amount of the alkyl polyglucoside sulfonate is less than 0.1% by weight, the cleaning effect is insignificant. When the amount exceeds 10% by weight, there is a problem in the formulation stability.

In the present invention, the cationic polymer is used for improving the feeling of use of the human body detergent composition, and at least one selected from the group consisting of polyquaternium-7, polyquaternium-10, and guar hydroxypropyltrimonium chloride, But is not limited thereto. Preferably, polyquaternium-10 as the cationic polymer may be used.

The cationic polymer may be contained in an amount of 0.1 to 3% by weight, preferably 0.2 to 1% by weight, more preferably 0.3 to 0.7% by weight based on the total weight of the composition. When the amount of the cationic polymer is less than 0.1% by weight, the effect of improving the feeling of use of the human body detergent composition is insignificant. When the amount exceeds 3% by weight, the stability of the composition is impaired.

The detergent composition according to the present invention may further comprise an auxiliary surfactant. The cosurfactant may be selected from the group consisting of alaninate, glycinate, sulfosuccinate, glutamate, sulfobetaine, and sarcosinate, and the like. Amino acid surfactants; Taurate; And isethionate, and the like.

More specifically, the amino acid surfactant is selected from the group consisting of N-cocoylalaninate, N-acylpotassium glycine, lauroyl glutamate, thiecocoyl alaninate, lauryl sarcosine, cocoyl sarcosine, Sarcosinate, and sodium cocoylalinate. However, the present invention is not limited thereto.

The detergent composition according to the present invention is excellent in the stability and cleaning effect of the detergent composition when the auxiliary surfactant, preferably an amino acid surfactant, more preferably allaninate, glycinate, or a mixture thereof is further included.

In the present invention, the cosurfactant may be contained in an amount of 0.1 to 10% by weight, preferably 1 to 9% by weight, more preferably 2 to 8% by weight based on the total weight of the composition. If the co-surfactant is less than 0.1% by weight, the effect of improving the cleaning ability is insignificant. If the co-surfactant is more than 10% by weight, there is a problem in formulation stability.

The alkylpolyglucoside sulfonate: cosurfactant is present in an amount of from 10: 1 to 1:10, preferably from 7: 3 to 3: 7 and most preferably of from 5: 5 (alkylpolyglucoside sulfonate: Active agent). A detergent composition comprising such a surfactant in such a weight ratio is excellent in stability and cleaning effect.

The detergent composition according to the present invention may comprise less than 0.1% by weight, preferably less than 0.01% by weight, based on the total weight of the composition of sodium lauryl ether sulfate (SLES), most preferably SLES I can not. The detergent composition according to the present invention has an advantage that skin irritation is remarkably reduced by replacing SLES, which is a surfactant, with alkylpolyglucoside sulfate.

In addition, the detergent composition according to the present invention may further include an amphoteric surfactant in order to enhance the cleaning effect, and the amphoteric surfactant is not particularly limited as long as it can be used in a common cosmetic composition, It is also possible to use amphoteric surfactants such as 2-undecyl-N, N, N- (hydroxyethylcarboxymethyl) -2-imidazoline sodium, 2-cocoyl-2-imidazolinium hydroxide- 2 sodium salt and the like); Betaine surfactants such as 2-heptadecyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, lauryldimethylaminoacetic acid betaine, alkylbetaine, amide betaine and sulfobetaine) But is not limited thereto. Preferably the detergent composition of the present invention may comprise cocamidopropyl betaine as an amphoteric surfactant.
