  • Patent number: 4675179
    Abstract: A cosmetic emulsion of low viscosity which comprises (a) 0.2 to 5 wt % of an emusifier, (b) 0.5 to 10 wt % of an oil and (3) 85 to 99.3 wt % of a water phase. The emusifier (a) consists essentially of a dimethylpolysiloxane-polyalkylene copolymer, a surface active agent having an HLB value not smaller than 10, and a linear, saturated higher alcohol having from 12 to 22 carbon atoms. The relative ratios of the dimethylpolysiloxane-polyoxyalkylene copolymer, the surface active agent and the higher alcohol lie within the polygon bounded by the points of a ternary composition diagram of the annexed figure.When the emulsion is applied to the skin, it gives refreshing feeling to the skin without any stickiness. It also gives appropriate moisture retentivity to the skin.
