Abstract:
A cosmetic raw material provides uniform dispersions of silicone oils and crosslinked silicone particles in cosmetic products. The cosmetic products consist of the cosmetic raw material combined with other types of cosmetic raw materials. This provides pleasant sensations of touch with the fingers and skin, improved rubbing properties, and sensation in their use. The method of manufacturing the cosmetic products has a high efficiency. The cosmetic raw material is made from a silicone oil emulsion containing crosslinked silicone particles having an average diameter of 0.05-100 &mgr;m which are contained in silicone oil drops having an average diameter of 0.1-500 &mgr;m, the drops in turn being dispersed in water. The diameter of the crosslinked silicone particles is less than the diameter of the silicone oil drops.
