  • Publication number: 20120045410
    Abstract: A hair cosmetic is provided in which the hair (hair style) can be set due to the adhesiveness thereof and yet which shows an excellent hair-arranging ability (including hair-restyling ability). Specifically disclosed is a hair cosmetic comprising, as a hair-setting resin, an adhesive setting resin which is obtained by combining and polymerizing monomers having specific structures and which shows an appropriate hardness and a high adhesiveness in a step of forming a film. In addition, this hair cosmetic preferably contains at least one component selected from a sugar, a sugar alcohol and an EO/PO derivative. Thus, a hair cosmetic having both a high hair-setting power and a good hair-arranging ability can be obtained.

  • Publication number: 20090047312
    Abstract: The present invention provides a microgel having a mean particle size of 0.1-1,000 ?m, the microgel being produced from a gel which is formed by use of a hydrophilic compound capable of forming a gel. An external composition containing the microgel provides an excellent sensation during use; i.e., the composition provides neither sticky sensation during use nor frictional sensation. Furthermore, even when a large amount of a pharmaceutical ingredient, such as a whitening ingredient, or a salt is incorporated into the composition, the viscosity of the composition is not lowered, and the composition exhibits excellent viscosity increasing property. In addition, the composition exhibits long-term stability, without inviting separation of water.
