An emulsion for hair treatment is provided which is characterized by the following: the formulation (I) is composed of a W/O type emulsion, which allows the main agent to be stable, and contains preferably an oil soluble polymer compound for the emulsifier; the formulation (I), upon being mixed with formulation (II), can easily undergo demulsification and a phase inversion into an O/W type emulsion; and the emulsion has adequate viscosity to prevent dripping from the hair and a superior dyeing capability. Also, 2-formulation type oxidation hair dye with an excellent hair dyeing effect is provided by adding isostearyl alcohol.
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.

A W/O type emulsified composition comprising an oil phase containing ethyl cellulose and a solvent capable of swelling ethyl cellulose and a water phase containing a water soluble polymer(s) emulsified as a water-in-oil type (W/O type) emulsion. A W/O type emulsified composition comprising an oil phase containing ethyl cellulose and a solvent capable of swelling ethyl cellulose and a water phase containing a polyion complex comprising cationized cellulose and sodium hyaluronate emulsified as a water-in-oil type (W/O type) emulsion.
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.
摘要:
An O/W/O type multiple emulsion in which an O/W type emulsion is dispersed in the outer phase oil wherein the O/W type emulsion in the inner phase contains water, an oil based ingredient, a surfactant and an amphiphilic substance chosen from those which can form a gel at ordinal temperature or higher in an amphiphilic substance-surfactant-oil-water system or N-long chain acyl acidic amino acid monosalt and an amphiphilic substance chosen from those which can form a gel at ordinal temperature or higher in an amphiphilic substance-N-long chain acyl acidic amino acid monosalt-oil-water system, said outer phase oil contains organophilic modified clay minerals and an emulsifying agent with a HLB of 7 or lower, and the weight ratio of the O/W type emulsion and the outer phase oil is 2:3-19:1. An O/W/O type multiple emulsion with superior stability over time and good usability.
