摘要:
A copolymer having silyl groups with at least one reactive functional group bonded thereto. The copolymer comprises a monomer (A) shown by the following Formula (I): wherein R1 is hydrogen atom or methyl; R2 is alkylene group having 1-6 carbon atoms; and R3, R4 and R5 each is a reactive functional group which can cross-link molecules of the copolymer by hydrolyzing. Further, the copolymer preferably comprises, as a constituent monomer, an alkyl (meth)acrylate and a siloxane-containing (meth)acrylate. A coating-forming method comprises hydrolyzing the composition on a material to be treated to cross-link molecules of the copolymer when on the material. A coating of the cross-linked copolymer has resistance to washing. This coating can modify the nature of hair, improve make-up retention, and provide skin-protecting. It can impart water-repellency, resistance to fouling, suitability as a sizing and crease resistance to fibers. Further, it can improve a skin-cleaning effect, applicability, strippability and coating-strength of a peeling-off type cosmetic pack.

摘要:
A production method of dry water containing an aqueous ingredient coated with a hydrophobic powder to form a powder state capable of liquefying upon embrocation at the time of use, wherein the dry water is produced by charging a hydrophobic powder and an aqueous ingredient into a hollow container forming a hydrophobic enclosed space in the inside thereof, followed by agitating at a high speed in the enclosed hydrophobic hollow container to form the aqueous ingredient to fine aqueous droplets, and then allowing the surfaces of the fine aqueous droplets to be uniformly adsorbed with the hydrophobic powder, whereby the dry water in the form of a powder state, but is capable of being liquefied upon embrocation at the time of use to be simply produced in a large scale.
摘要:
The present invention is a thickener consisting of a microgel obtained by radical polymerization of water soluble ethylene-type unsaturated monomers dissolved in the dispersion phase in a composition having an organic solvent or an oil component as the dispersion medium and water as the dispersion phase, as well as a cosmetic containing said thickener.Also, the present invention is a method of manufacturing a water-swelling polymer in a radical polymerization system consisting of a composition having an organic solvent or oil component as the dispersion medium and an aqueous solution of a water soluble ethylene type unsaturated monomer as the dispersion phase wherein said system contains a surfactant chosen in such a way that the aforementioned composition forms a single phase W/O microemulsion or fine W/O emulsion at a thermal radical polymerization temperature and said thermal radical polymerization is carried out at a temperature equal to or higher than the phase transition temperature of the radical polymerization system, yet not higher than the phase transition temperature by 20° C. or more.

摘要:
A gelation agent or an emulsifying agent is provided which is obtained by mixing a water swelling clay mineral with a quarternary ammonium salt type cation surfactant and a fatty acid or a higher alcohol which is liquid at normal temperatures. The present invention can provide a gelation agent or an emulsifying agent which can be added and mixed to a wide range of oils to produce a gel composition or an emulsified composition with superior stability, safety and usability. The gelation agent or the emulsifying agent of the present invention or the gel composition or the emulsified composition using this agent is preferably used as the base agent of cosmetics and quasi-drugs, for example. Also, the sunscreen cosmetic prepared by adding ultraviolet light protection powder to the aforementioned emulsified composition exhibits superior usability, i.e. it exhibits good adhesion to the skin and superior water resistance and it does not become conspicuous when the applied site comes in contact with sweat or water from the ocean or pool. Therefore, it is particularly useful when a high ultraviolet light protection effect is desired because it allows the required amount of the ultraviolet light protection powder to be blended in without concern for conspicuous whiteness.
