Abstract
The present invention is directed to a shaving system of the wet shave type comprising a blade member (one or more) and a structure which supports or holds the blade member and which has an external skin engaging portion in proximity to the blade member. The skin engaging portion includes an improved shaving aid composite (or lubricating strip) which contains an inclusion complex of a skin-soothing agent, such as menthol, with a cyclodextrin. Preferably the shaving aid composite comprises a matrix of a water-insoluble polymer, an effective amount of a skin lubricating water-soluble polymer dispersed within the matrix, and an inclusion complex of a skin-soothing agent with a cyclodextrin. Alternatively, the shaving aid composite may comprise a sheath of water-insoluble polymer that surrounds a core which includes a skin-lubricating water-soluble polymer and an inclusion complex of a skin-soothing agent with a cyclodextrin. The improved shaving aid composite is capable of retaining during normal storage conditions substantially all of the skin-soothing agent included during fabrication of the composite and delivering an effective amount of the skin-soothing agent during use.
