A polyorganosiloxane emulsion composition characterized by comprising (A) a polyorganosiloxane, (B) an N-acylalkyl taurine and/or a salt thereof, and (C) water, the content of cyclic organosiloxane oligomers in said component (A) being within 3.5 wt. %, and a cosmetic raw material characterized by consisting of said polyorganosiloxane emulsion composition. The emulsion composition is characterized by superior cosmetic functionality in terms of moisture and smoothness.

Polyorganosiloxane emulsion composition and a cosmetic material made therefrom

A cosmetic raw material possesses excellent compounding stability in cosmetic products. The cosmetic raw material is produced from a vinyl-type polymer having a carbosiloxane dendrimer structure in its side molecular chain. The cosmetic raw material is composed of the vinyl-type polymer having a carbosiloxane dendrimer structure in its side molecular chain, and a solution or a dispersion of a liquid such as a silicone oil, organic oil, alcohol, or water.

Cosmetic raw material cosmetic product and method for manufacturing cosmetic products

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.
