Description

  The present invention relates to a hair cleansing composition that has good foaming and can impart a feeling of gloss to dried hair.

  In recent years, women's hair has become more susceptible to physical damage due to daily hair washing, styling, hair dryer, and the like, and chemical damage due to hair dyeing, bleaching, perm treatment, and the like, with an increasing awareness of cleanliness and fashion. Problems with damaged hair include a feeling of squeaking when shampooing is rinsed, hair dryness after drying, deterioration of smoothness, reduction of glossiness, combing deterioration, and the like.

  As a means for solving such inconveniences, a shampoo composition containing a cationic surfactant or a long-chain aliphatic alcohol as a rinsing component allows the liquid crystal (cationic surfactant) to be used when the hair is rinsed. And long-chain aliphatic alcohol aggregates) are adsorbed on the hair to express smoothness, suppress the dryness of the hair after drying, adjust the condition of the hair after drying, and improve the finishing touch. (See Patent Documents 1 and 2). However, in this cationic surfactant-containing system, since the cationic surfactant and the anionic surfactant form an anion-cation complex, the amount of the anionic surfactant is large (about 5% by mass). This is a problem in that it is easy to separate and the foaming becomes worse.

  Examples of conventional foam modifiers for shampoo compositions include fatty acid alkanolamides, monoglycerides, and various ionic polymers (see Patent Documents 3 to 5). However, these are not effective unless they are added in large amounts, and when they are added in such an amount that they are sufficiently effective, stickiness, hardness and stiffness unique to polymers occur during repeated hair washing, etc. It was a problem.

  Accordingly, the present situation is that there is a need to provide a hair cleansing composition that is excellent in foaming, can give gloss to dried hair, and has good separation stability.
