Abstract
The present invention provides a hair cosmetic composition contains (A) a di-long-chain cationic surfactant represented by formula (1); (B) an ethylene oxide adduct of 1,2-alkanediol represented by formula (2) and/or an N-acyl-N-methylmonoethanolamide represented by formula (3); and (C) a hydrophobicized alkyl cellulose represented by formula (4) and/or a cationic polymer represented by formula (5), and (D) water (chemical formulas not shown). The hair cosmetic composition has remarkably high safety and excellent stability. In addition, the composition exhibits excellent spreadability over hair upon application thereof and can finish hair with suppleness and less stickiness. Also, even when the composition has a low base material content, a lamellar liquid crystal structure can be formed. Quite surprisingly, the hair cosmetic composition can provide hair with conditioning effects together with excellent viscoelasticity and shows such excellent performance as to cause no problem even though the rinsing step is omitted.
