ABSTRACT:
This invention provides water-absorbing polymer particles suitable particularly for cosmetics, wherein silicone can be stably present on the surface of a water-absorbing polymer even in various formulations thereby giving dry feeling in use even after water absorption. The silicone-modified water-absorbing polymer particles of this invention comprises water-absorbing polymer particles coated thereon via chemical bonding, with a silicone compound having at least one functional group.
