ABSTRACT:
A skin-contacting lubricating layer formed from a 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 a 6-18C alkyl or alkenyl group, such as an N-hexadecyl group) or a long chain fatty amine so as to substantially improve the lubricity of the layer with respect to damp skin.
The hydrogel polymer is preferably a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) or with 2-ethylhexyl acrylate (EHA) or with both MAA and EHA. Such a hydrogel polymer has improved 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.
