Description

Shampoo composition improving dry feel "

The present invention relates to a shampoo composition, and more particularly to a conditioning shampoo composition comprising a gel-network phase.

In general, shampoo is used to keep hair and scalp clean and beautiful by removing contamination of hair and scalp, but it is also used for additional shine and protection of hair.

In recent years, effort to impart softness and shine to hair has been continuously increasing. Generally, after using shampoo, conditioner, treatment, hair essence, oil, etc. are applied to the hair. However, there is a need to apply a separate product after using the shampoo.

Therefore, efforts to increase the adsorption amount of the conditioning agent to the hair even after cleaning have been continuously researched to solve such a problem.

Alcohols and cationic surfactants, which generally improve the softness of hair, have some disadvantages in that the conditioning effect is increased to some extent but the effect is insufficient and the stability of the shampoo is deteriorated.

Recently, in order to compensate for these disadvantages, U.S. Patent Publication No. 2003/0223952 discloses a method for improving quality after applying a gel network image containing alcohol, an emulsifier, and a surfactant to a shampoo. However, when a gel network using an alcohol, an emulsifier and a surfactant is applied to a shampoo, the stability of the product deteriorates over time and there is a limit to obtaining a desired quality level.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a shampoo composition which is excellent in conditioning effect and secures stability over time by using a gel-network phase.

According to an aspect of the present invention, Cationic surfactants; And a gel-network phase using a surfactant having at least two hydrophilic and hydrophobic moieties in the molecule.

Hereinafter, the shampoo composition of the present invention will be described in more detail.

Alcohols, commonly known as conditioning agents that improve softness after drying, have some disadvantages that, when applied to shampoo, improve quality to some extent after drying but impair low temperature stability. In addition, cationic surfactants increase the conditioning effect to some extent when applied to shampoo, but they have little effect and inhibit stability because they form strong complex with anion when used alone.

To compensate for these shortcomings, the gel network image that is applied to various items of cosmetics is applied to forming shampoo. The gel network phase is formed at a specific concentration range by using alcohol, surfactant and water. However, there is a limit to improve the quality and improve the low temperature stability after drying, and an emulsifier may be used to stabilize the gel network phase. Not enough.

In order to overcome such disadvantages, the present invention can improve the stability of the gel network by using a surfactant having two or more hydrophilic moieties and hydrophobic moieties in the molecule and improve softness after drying the hair.

The gel network of the present invention is characterized in that it contains at least one selected from alcohols and emulsifiers, a cationic surfactant and a surfactant having at least two hydrophilic and hydrophobic moieties in the molecule and is usually applied to shampoo Thereby increasing the conditioning effect on the hair and stabilizing the gelatine phase, thereby improving the stability when applied to the product.
