Description

  The present invention relates to a gel hair composition.

A hair composition such as a styling agent is usually taken out from a container at the time of use and applied to the hair. Cosmetics for hair are required to have an adhesive property (hereinafter referred to as setting force) that can keep the shape when applied to hair and a glossy appearance (hereinafter referred to as gloss).
In recent years, there has been a demand for a composition for hair that does not have stickiness with hands or hair, while having a setting power and a glossy feeling. As such a composition, a gel-like composition containing both a cationic polymer that achieves a setting force and a glossy feeling and an anionic polymer that provides freshness has been proposed (Patent Documents 1 and 2). reference).
The composition containing the cationic polymer and the anionic polymer has a bond formed between the positively charged portion of the cationic polymer and the negatively charged portion of the anionic polymer to form a composite, and A weak bond occurs between the adjacent composites, and the gel can be thickened to form an elastic gel.
