Description

  The present invention relates to a hair cosmetic, and more specifically, it has excellent effect of straightening hair and straightness sustainability, has no stickiness, imparts natural luster and smoothness to the hair, and provides gloss The present invention relates to a hair cosmetic that is excellent in smoothness sustainability.

  In recent years, hairstyles have been diversified, especially in younger teenagers and twentieth generations, who long for straight hair that flutters in the wind, and various hair cosmetics are used for that purpose. Examples include hair gels, hair creams, hair foams, hair lotions, etc. These are generally formulated as components that exhibit a straight effect from oil components such as silicone oils, ester oils, hydrocarbon oils, and polymer compounds that have film-forming ability. Has been. Among these components, liquid oils typified by silicone oil are widely used for the purpose of imparting the feel and gloss of hair. By blending a cationic surfactant and a silicone resin, a hair cosmetic (for example, see Patent Document 1) that can efficiently bond the split ends of hair, a plant protein derivative, and a cationic surfactant A hair treatment agent characterized by containing silicone (for example, see Patent Document 2), a hair comprising a cationic surfactant, maleic acid-modified ester gum, and silicone oil Cosmetics (see, for example, Patent Document 3) disclose an effect of imparting good smoothness and moist feeling to hair upon finishing after use on hair. However, these silicone-containing compositions have a limit in the effect of actually straightening hair, and have not reached a satisfactory level.
