It relates to an O/W emulsion which can be inverted to a W/O emulsion and the W/O emulsion inverted from the O/W emulsion, wherein the O/W emulsion is obtained from radical polymerization under emulsion polymerization reaction condition of at least one polyorganosiloxane having at least two aliphatic unsaturated carbon-carbon bonds, and optionally an organohydrogen-polysiloxane, in the presence of a polyether-modified polysiloxane. It also relates to preparation process of the O/W emulsion and the W/O emulsion, and a personal care composition containing the emulsion.

A method for makeup including (A) applying to skin a composition X including components (A1) and (A2). (A1) includes a polymer containing a norbornane moiety and/or a silicone-modified Pullulan and (A2) includes a volatile oil. The method further includes (B) applying to the skin a composition Y including a component (B1), other than the composition X, where (B1) includes one or more selected from the group consisting of polyols and liquid oils.

A composition for external preparation for skin including the following components (A), (B), and (C). (A) includes from 1 to 30 mass % of a polymer having a silicone moiety in which a ratio of deformation is 0.3 or more and 1 or less, and in a bend resistance test using a cylindrical mandrel method a minimum diameter of a cylindrical mandrel which causes no cracks in a polymer film is 2 mm or longer and 25 mm or shorter. (B) includes a volatile oil having a volatilization rate of 14% or more after drying at 1 atmosphere, at 40° C., and an R.H. of 60% for 30 minutes.

The present invention provides an oil-in-water emulsion composition thickened with a hydrophobically modified polyether urethane, the composition having improved high-temperature stability and giving a pudding-like unique feeling. The invention provides an elastic jelly-like composition characterized in that a hydrophobically modified polyether urethane has been incorporated into an oil-in-water emulsion including oil droplets with an average particle diameter of 150 nm or smaller. The elastic jelly-like composition is transparent or translucent, gives a pudding-like elastic feeling, has excellent viscosity stability at high temperatures, and is suitable for use as a cosmetic-preparation base. The hydrophobically modified polyether urethane is especially preferably a PEG-240/decyltetradeceth-20/HDI copolymer.
