JP5222485B2 - Foam hair cosmetic - Google Patents

Description

  The present invention has excellent foamability and fine foam quality even at low temperature, excellent stability of aerosol stock solution, and when applied to hair, it feels good when used as a finger and gives natural gloss to hair It is related with the foam-like hair cosmetics which can do.

  Silicone derivatives are generally used to improve the feel of touching the hair, such as the feeling of fingering, and to give natural luster. However, since many silicone derivatives have antifoaming properties, It is very difficult to obtain sufficient foaming properties, particularly at low temperatures, in spite of fineness and sustainability. Moreover, it is unstable as an aerosol stock solution, and the process up to filling is not easy, for example, stirring cannot be stopped until the aerosol container is filled.

For example, aerosol cosmetics (see Patent Document 1) containing an oily component and a polyglycerin fatty acid ester are disclosed, and it is shown that a foam interface that is hard to break can be obtained even if silicone is contained. Also, an aerosol composition (see Patent Document 2) containing an amine oxide group-containing resin, a silicone aqueous emulsion, and a surfactant is disclosed, and foaming properties at low temperatures and excellent usability can be obtained. It is shown.
Fatty acid alkyl alkanolamides have been found to be effective in detergent compositions (see Patent Documents 3 and 4), but emulsification of silicone derivatives in foamed hair cosmetics containing stock solutions and propellants. There is no recognition that it is excellent in dispersibility and foaming properties.

  All of the above conventional techniques have been improved as an aerosol composition. For example, the effects expected of silicone derivatives, such as an improvement in touch such as a finger feeling to the hair and an effect of imparting natural gloss, etc. In addition, satisfactory characteristics such as foamability at low temperature and fine foam quality are not sufficiently obtained. Furthermore, since the stability of the aerosol stock solution is not sufficient, the filling process is not easy.

  As a result of intensive studies to achieve the above-mentioned objective, by using a specific fatty acid alkyl alkanolamide type nonionic surfactant and a silicone derivative, excellent foamability and fine foam quality can be obtained even at low temperatures, It has been found that the stability of the aerosol stock solution is excellent, and when applied to hair, the feeling of use such as passing through fingers is good, and that natural luster can be imparted to the hair.
