Provided are a raw material for a cosmetic and an oil-in-water emulsion cosmetic comprising a core-corona polymer particle excellent in emulsion stability and feeling of use. Certain embodiments of the present invention provides a raw material for a cosmetic, comprising a core-corona polymer particle dispersion obtained by radical-polymerizing a polyethylene oxide macromonomer represented by formula (1) and one or two or more of hydrophobic monomers represented by formulas (2) and (3) under conditions (A) to (D).

Provided are high slip and shine cosmetic compositions capable of forming a multilayer structure after application to a keratinous material. Certain compositions comprise (a) Component A which comprises (i) about 0.01% to 60% by weight of least one silicone-containing and/or hydrocarbon-containing film forming agent; (ii) about 0.01 to 20% by weight of at least one phenylated silicone; (iii) about 0.01 to 20% by weight of at least one siloxane polymer wax; and (b) Component B which comprises; (i) about 0.01% to 90% by weight of the composition of one or more silicone compounds in amounts sufficient to achieve a viscosity of about 1,000 cSt to 10,000,000 cSt; wherein the Component A and Component B are immiscible.
