This relates to an improved skin engaging member for use in razor blade; cartridge assemblies and shaving systems of the wet shave type. In an embodiment, there is provided a two-component, control-release shaving device consisting of(a) a sheath layer made from thermoplastic resins with openings therein and (b) a core region containing internal shaving aids. Potentially, the device can maintain surface appearance, control-release the shaving aids, minimize the degradation of the shaving aids, and prevent the shaving aids from being trapping in a strip. Furthermore, the addition of low-melt additives to the shaving aids becomes feasible and the compatibility between the shaving aids and the shaving aid carrier such as polystyrene in the lubricating strip composite becomes less critical.

[ What is claimed is:] [1.]1. A razor cartridge comprising a blade and a skin engaging member affixed adjacent said blade, said skin engaging member comprising, prior to and after assembly into said razor cartridge,an elongated solid polymeric sheath comprising a water insoluble polymer, said sheath having a skin engaging surface extending along an outer surface thereof, andan internal solid polymeric core integrally formed with said sheath and extending axially throughout and surrounded by said sheath, said core containing 50% to 100% by weight of a solid shaving aid, said solid shaving aid comprising a water soluble polymer,wherein said sheath has at least one opening in said skin engaging surface through which said shaving aid is released during shaving.
