Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic composition. [Background technology]

[0002]

[0003] Conventionally, in hair cosmetic compositions such as shampoos, cationic polysaccharides such as cationic cellulose and cationic guar gum, and silicones have been used to impart conditioning effects. The use of these cationic polysaccharides and silicones improves the moist feeling and smoothness of hair after drying, but if they are incorporated in large amounts to fully achieve these effects, a strong sticky feeling remains. Therefore, various studies have been conducted to achieve both moist feeling and smoothness of hair and non-stickiness.

[0003] For example, Patent Document 1 discloses a hair wash composition containing an anionic surfactant and / or an amphoteric surfactant, a cationic polysaccharide, an anionic polysaccharide, and isoprene glycol. [Prior art documents] [Patent documents]
