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, the shampoo is used to remove the contamination of the hair and scalp to keep it clean and beautiful, and is also used for the purpose of giving shine and protecting the hair.

Recently, efforts to give softness and shine to hair have been continuously increasing. Generally, after shampoo is used, conditioners, treatments, hair essences and oils are applied to the hair. However, there is a need to apply a separate product after using the shampoo.

Therefore, in order to solve this problem, efforts to increase the adsorption amount of the conditioning agent on the hair even after cleaning have been constantly studied.

In general, alcohol and cationic surfactants to improve the softness to the hair, although the conditioning effect is somewhat increased, but the effect is insufficient and has the disadvantage of inhibiting the stability of the shampoo.

Recently, US Patent Publication No. 2003/0223952 discloses a study to improve the quality after drying a gel network phase containing alcohol, emulsifiers and surfactants in a shampoo to compensate for this drawback. However, when gel phases with alcohols, emulsifiers and surfactants are applied to shampoos, the product's stability over time and the desired quality level is limited.

Therefore, the technical problem to be achieved by the present invention is to provide a shampoo composition that is excellent in the conditioning effect and ensured stability over time using a gel-network phase.

In order to achieve the above technical problem, the present invention is any one or more selected from alcohol and emulsifier; Cationic surfactants; And a gel-network phase using a surfactant having two or more hydrophilic and hydrophobic moieties in the molecule.

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

In general, alcohol, known as a conditioning agent that improves softness after drying, improves the quality after drying to some extent when applied to shampoo, but has a disadvantage of inhibiting low temperature stability. In addition, the cationic surfactants increase the conditioning effect to some extent when applied to the shampoo, but the effect is insufficient, and when used alone, it inhibits stability because it forms a strong complex with the anion.

To compensate for this drawback, the gel network phase applied to various cosmetic products is applied to the forming shampoo. Gel network phases are formed in specific concentration ranges using alcohols, surfactants, and water, which also have limitations in improving quality and drying stability after drying, and emulsifiers may be used to stabilize the gel network phase, but the effect is Incomplete

In the present invention, in order to compensate for this disadvantage, by using a surfactant having two or more hydrophilic and hydrophobic moieties in the molecule, it was possible to improve the stability on the gel network and to improve the softness after drying the hair.

In order to form the gel network of the present invention, at least one selected from alcohols and emulsifiers, cationic surfactants and surfactants containing two or more hydrophilic and hydrophobic moieties in the molecule may be used.
