  • Method for evaluating hair damage using an oxidized protein in hair as an indicator
    Publication number: 20070110670
    Abstract: The present invention provides a method for evaluating hair damage. The method comprises specifically labeling the carbonyl group of an oxidized protein in hair with fluorescence and detecting the fluorescence. The damage can be caused by any of perm treatment, bleach treatment, treatment with an oxidation hairdye, combing, heat treatment, exposure to ultraviolet rays, and exposure to hypochlorous acid in swimming pools, or a combination thereof.

  • Hairdressing cosmetic preparation and hairdressing method using the same
    Patent number: 6649154
    Abstract: The hairdressing cosmetic preparation of the present invention is characterized by comprising a heat-gelling polymer which becomes to gel upon heating. The gelling temperature of the heat-gelling polymer is preferably 60° C. or higher. Preferable heat-gelling polymer is polysaccharides such as &bgr;-1,3-glucan, &bgr;-1,3-xylan, curdlan and the like. The hair dressing preparation of the present invention, due to using such heat-gelling polymer, can give excellent hairdressing effect and hair-setting power when hair applied with the hairdressing preparation is treated with heating.

  • Microgel and external compositions containing the same
    Publication number: 20030072805
    Abstract: The present invention provides a microgel having a mean particle size of 0.1-1,000 &mgr;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.
