Abstract: The disclosure deals with a lubricative skin engaging member with progressive release of lubricating polymer from a water-insoluble matrix containing thermoplastic elastomer compound and maleic anhydride copolymer and lubricating polymer in concentration less than 30%. The disclosure lies in the use of the maleic anhydride in grafted form on polyethylene and the incorporation of water-soluble lubricating polymer in concentration less than 30% in the thermoplastic elastomer compound, leading to a lubricative mixture, and to a skin engaging member, with increased homogeneity and water absorption ability that assist in the lubricating polymer release in a progressive and controllable manner.

Abstract: A retaining element for a razor cartridge has a top portion that includes an aperture therethrough, a bottom portion, and a side portion connecting the top portion to the bottom portion to define a volume between the top portion and the bottom portion, a container having a top opening, a lubricating composition in the container and a first spherical lid to cap the container. The top opening is sized to hold the first spherical lid so that the first spherical lid freely rotates without translation. The container is positioned in the volume so that the first spherical lid at least partially protrudes from the aperture. The lubricating element emits onto an outer surface of the first spherical lid when the first spherical lid rotates.
