Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hair rinse agent composition, more specifically, to a hair rinse agent composition which, when applied to the hair, exhibits good spreadability and has excellent rinsing effects such as smoothness and suppleness on the hair. The present invention relates to a hair rinse agent composition that imparts.

Aikama's hair rinse agent gives flexibility and antistatic properties to the hair.
A hair rinse agent is used to make hair easier to comb through and handle, and is used after washing the hair by dissolving or dispersing it in hot water. However, in order to treat the hair more effectively, it is preferable to apply the hair rinse agent directly to the hair. In this case, unless the hair rinse agent spreads well, it will not spread throughout the hair, resulting in uneven rinsing effects. Therefore, quaternary ammonium salts and various oils such as higher alcohol lanolin derivatives, fatty acid esters, silicones, etc. are usually added to hair rinses.

However, if a large amount of these ingredients are blended, the hair rinse agent becomes sticky due to the oil content, and if the blend is too small, a sufficient length of hair cannot be obtained.

Purpose of the Invention As a result of our research in order to improve the above-mentioned drawbacks, to obtain an excellent hair rinse agent that spreads well during application, has a smooth finish, and is not sticky, we have developed a hair rinse agent that has a smooth and non-sticky finish. The effect can be further enhanced by using a cationized polymer having special properties together with polyoxyethylene polyoxypropylene alkyl ether, polyoxypropylene alkyl ether, or a mixture thereof that provides lubricity.
The present inventors have discovered that a hair rinse agent with good properties can be obtained, and have completed the present invention.
