The present invention is directed to a shaving system of the wet shave type comprising a blade member (one or more) (20, 24) and a structure (12) which supports or holds the blade member (20, 24) and which has an external skin engaging portion (34) in proximity to the blade member. The skin engaging portion (34) includes an improved shaving aid composite (42) which comprises a non-volatile cooling agent, such as a non-volatile menthol analog. Preferably the shaving aid composite (42) comprises a matrix of a water-insoluble polymer and, dispersed within the matrix, a skin lubricating water-soluble polymer and a non-volatile cooling agent. Alternatively, the shaving aid composite (42) may comprise a sheath of water-insoluble polymer that surrounds a core which includes a skin-lubricating water-soluble polymer and a non-volatile cooling agent. The improved shaving aid composite (or lubricating strip) is capable of retaining during normal storage conditions substantially all of the cooling agent included during fabrication of the composite and delivering an effective amount of the cooling agent during use.
L'invention concerne un système pour rasage du type humide, comprenant un élément avec une ou plusieurs lames (20, 24) et une structure (12) qui supporte ou tient l'élément à lame(s) (20, 24) et qui a une portion externe (34) de contact avec la peau près de l'élément à lame(s). La portion de contact (34) avec la peau comprend un composite (42) facilitant le rasage qui contient un agent rafraîchissant qui est non volatil, tel qu'un analogue non volatil du menthol. De préférence, le composite (42) facilitant le rasage comprend une matrice d'un polymère insoluble dans l'eau et, dispersé dans la matrice, un polymère hydrosoluble lubrifiant pour la peau et un agent rafraîchissant qui est non volatil. Egalement, le composite (42) facilitant le rasage peut comprendre une gaine en un polymère insoluble dans l'eau qui entoure un noyau comprenant un polymère hydrosoluble lubrifiant la peau et un agent rafraîchissant non volatil. Le composite amélioré facilitant le rasage (ou bande lubrifiante) est capable de retenir, dans des conditions de conservation normales, sensiblement tout l'agent rafraîchissant pour la peau incorporé au cours de la fabrication du composite et de fournir durant le rasage une quantité adéquate d'agent rafraîchissant.
