Description

Shampoo composition

The present invention is a cationic surfactant; Ethoxylate glucoside derivatives; A shampoo composition containing a mixture of polyethylene glycol ethers of polyacrylamide, isoparaffin and lauryl alcohol (hereinafter referred to as laureth), in particular, hypoallergenic, tricot and The present invention relates to a shampoo composition having a smooth feel after drying, a feeling of combing in a wet state, a conditioning effect after drying, and the like.

Originally, the most basic function of the shampoo was to remove contaminants from the hair and scalp.However, according to various changes in the surrounding environment for hair protection, the use and after use of the shampoo, good finish, mildness, conditioning effect, simplicity, etc. It is required.

Cationic polymers and silicone derivatives among the components of the conventional shampoo composition are widely used for the purpose of providing softness and smooth feel to hair after hair washing. However, conventional products containing them are sticky during drying. In addition, the lack of texture and hairiness after drying and lack of hair shine and moisturizing, as well as build up (Build up) phenomenon, there was a disadvantage that the conditioning effect after drying does not last for a long time.

Therefore, there have been various studies to improve such disadvantages.

For example, International Patent No. PCT / US92 / 09237 (Procder & Gamble) describes a shampoo composition containing a cationic polymer and a silicone, oily liquid conditioning agent. However, while the composition uses an appropriate blend of oily liquid conditioning agents in cationic polymers and silicones to improve build up and induce a conditioning effect, these shampoo compositions generally prevail in terms of foaming and cleansing but are irritating to eyes and skin. Since this anionic surfactant is used as a periodic agent, it also removes the contaminants attached to the hair and also removes the protein components of the hair and irritates the eyes and the skin. There were disadvantages such as only felt.

In addition, Japanese Patent Application No. 91-199018 (Kao) contains a quaternary ammonium salt compound having a secondary or tertiary amino group and a quaternary ammonium group and a silicone derivative in an ether, ester or acyl compound having an aliphatic ring or an aliphatic ring. Shampoo compositions are described. However, the composition induces hypoallergenicity by using a new quaternary ammonium salt compound with foaming power and detergency as a main surfactant and an anionic surfactant as an auxiliary base, but it is very irritating to the eyes and may cause discomfort when used. Also, there is a disadvantage in that the bubble is sticky and the feeling is bad, and the imparting conditioning effect does not last long.

Therefore, a shampoo composition having excellent conditioning effect is required, such as improving the texture of the hair and skin while being hypoallergenic, the texture after drying, the moisture, the gloss, the conditioning effect, and the added conditioning effect lasts until the next day of hair. have.

As a result of continuing the experiment to solve the above problems, excellent conditioning effect cationic surfactant; Ethoxylate glucoside derivatives; Shampoo composition containing a mixture of polyacrylamide, isoparaffin, and lautzate is hypoallergenic to hair and skin, smooth texture after hair and after drying, wet feeling after combing, moisture after drying, shine, conditioning effect The present invention has been found to be excellent and the present invention completes the present invention by discovering that the imparted conditioning effect lasts until the next day of tricycle.

In the shampoo composition of the present invention, it is preferable to use within the weight ratio ranges of a, b, and c.

Comparing the skin irritation properties of the shampoo compositions of Examples 1 to 9 and Comparative Examples 1 to 13, Comparative Example 2 and Comparative Example were used when the cationic surfactant and the ethoxylate glucose derivative were mixed within the weight ratio ranges of a and b. The compositions of 10 and Examples 1-9 showed significantly lower skin irritation, but when the weight ratio of polyacrylamide, isoparaffin and lauret in component c is outside the ranges given above (Comparative Examples 12, 13) A stimulus phenomenon appeared.

And when component c is used in excess of the weight ratio given above (Comparative Example 11) or b, c component is used within the range given above, but when the cationic surfactant is used in excess (Comparative Example 7) There was a marked increase.

However, the effect of reducing skin irritation no longer appeared even when component b was used in excess as in the case of Comparative Example 9.

In addition, the phase stability and the conditioning effect compared to Example 1, when the weight ratio of the component c is out of the range given above (Comparative Examples 10, 11), the phase stability was lowered and the conditioning effect was lowered.

And in the composition of the present invention it can be seen that not only the weight of the component c, but also the weight ratio of the polyacrylamide, isoparaffin and lauret constituting the component c is very important. That is, when the above three components are formulated within the weight ratios shown (Examples 8 and 9), characteristics such as softness, smoothness, moistness and gloss are greatly improved, while the weight ratios of the three components are outside the ranges given above. (Comparative Examples 12 and 13) showed a poor conditioning effect and poor phase stability.

When the ethoxylate glucose derivative was used outside the range of the above-described weight ratio (Comparative Examples 8 and 9), phase stability was not secured and the synergistic effect of conditioning was not observed.

And when the cationic surfactant is used less than the weight ratio range previously suggested (Comparative Example 6), there was no synergistic effect of conditioning, and when the cationic surfactant is used more than the proposed weight ratio range (Comparative Example 7), the skin irritation was not only increased. Degradation of stability and build-up phenomenon resulted in a poor conditioning effect.

As seen in the above examples and comparative examples, it can be seen that it is most effective to combine the components a, b and c within the range of the weight ratio and to use polyacrylamide, isoparaffin and laureate properly. That is, in the preparation of the shampoo composition of the present invention, when the three components are blended within the given weight ratios (Examples 8 and 9), the characteristics such as softness, smoothness, moistness and gloss are greatly improved, whereas In the case of out of range (Comparative Examples 12 and 13), the conditioning effect was inferior and phase stability was bad. Therefore, the shampoo composition of the present invention is hypoallergenic to the skin and hair than the conventional shampoo composition and is excellent in the smooth feeling after washing and drying, and also excellent in combing in wet conditions, moisturizing after drying, shine and conditioning effect. It can be seen that the granted conditioning effect lasts until the next day of tricycle.

Combinations of the weight ratios presented above may vary slightly depending on the particular components used in the present invention, but are not limited to the above examples.
