An aqueous composition used for cosmetics, characterized in that the composition comprises 0.5 to 50 wt %, based on weight of the composition, of a copolymer having main chains comprising the repeating units represented by the following formula (1), the repeating units represented by the following formula (2), and the repeating units represented by the following formula (3), said main chains being crosslinked by a compound or oligomer having 2 to 6 (meth)acryl groups wherein Ris a hydrogen atom or a hydrocarbon group having 1 to 3 carbon atoms, Ris a hydrocarbon group having 1 to 24 carbon atoms, Ris a divalent hydrocarbon group having 1 to 4 carbon atoms, Ris an aliphatic hydrocarbon group having 1 to 6 carbon atoms or a phenyl group, X is a hydrogen atom, an alkaline metal ion, ammonium ion, or an organic ammonium ion, m is an integer of from 0 to 500 on average, and n is an integer of from 1 to 3.

Silicone copolymer and cosmetics comprising the same

An emulsion composition for building exterior walls is provided comprising in admixture, [A] a graft copolymerized emulsion obtained by adding to (1) an oil-in-water type emulsion containing at least one organopolysiloxane having an organic group containing a radical reactive group or SH group, (2) a monomer or monomeric mixture containing at least 70 wt % of at least one monomer selected from acrylic and methacrylic monomers and effecting emulsion graft polymerization of component (2) to the organopolysiloxane, and [B] a silicone resin-containing emulsion. The emulsion composition is capable of forming an elastic, flexible coating which is endowed with water resistance, weather resistance, water repellency, adhesion and heat resistance and maintains these properties over a long period of time. It can thus be used as a base in a variety of paints and coating agents.
