RESIN COMPOSITION FOR COSMETIC AND COSMETIC USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for cosmetics, enabling a plurality of performances required for cosmetics to be met simultaneously through using a resin having a combination of two or more properties, and to provide cosmetics using the resin composition. SOLUTION: This resin composition for cosmetics includes a block copolymer which has constituent unit derived from a compound bearing an ethylenically unsaturated bond, a number-average molecular weight of 1.0×10<3> to 1.0×10<6> and at least two glass transition points or melting points; wherein it is preferable that the block copolymer has at least one block composed of hydrophilic group-bearing constituent unit. The other objective cosmetics using the above resin composition are provided.
