Abstract
A skin – contacting coating of a lubrjcating hydrogel polymer bonded to a rubber article ( such as a surgeon’s glove) is treated by means of surfactant material ( such as a bactericidal cationic surfactant which preferably has an N-hezadecyl group) or a long chain fatty amine so as to substantially improve the lubricity of the coating with respect to damp skin The hydrogel polymer is preferably a copolymer of 2- hydroxythyl methacrylate(HEM) with methacrylic acid(MAA) or with 20 ethyl hexyl acrylate(EHA) or with both MAA and EHA, the copolymer conatins HEMA and MAA is a molar ratio of 1 to 10 :1 of HEMA and EHA is a molar ratio of 2.5 to 10:1 such a hyfrogel polymer has Impooved lubricity to dry skin and if used for this purpose , need not be treated with a surfactant or fatty amine to improve the lubricity with respect to damp skin.
