摘要： Provided is an elastomer that improves the skin feel of an inorganic powder. The elastomer according to the present invention is an elastomer comprising: (A) an amino group-containing silicone polymer; and (B) a carboxyl group-containing silicone polymer or a carboxyl group-containing acrylamide polymer, wherein a molar ratio Y/X between amino groups and carboxyl groups is within a range of 0.1 to 1.2, wherein Y denotes the molar amount of carboxyl groups contained in the component (B), and X denotes the molar amount of amino groups contained in the component (A).

摘要： Provided is an elastomer that improves the skin feel of an inorganic powder. The elastomer according to the present invention is an elastomeric mixture comprising an amino group-containing silicone polymer and a carboxyl group-containing silicone polymer or a carboxyl group-containing acrylamide polymer. The molar ratio of amino groups to carboxyl groups in the mixture is within the range of 0.1 to 1.2.
