Abstract

A skin engaging shaving aid member suitable for use in a shaving device, said skin engaging shaving aid member comprising a thermally resilient sensate such as N-substituted menthanecarboxamide.

Claims (17)

1. A skin engaging shaving aid member, said skin engaging shaving aid member comprising:

a. a matrix comprising at least one of: a water soluble polymer, an emollient, and a soap base, wherein the water soluble polymer is at a level of from about 50% to about 100%, by weight of the matrix;

b. from about 5% to about 15%, by weight of the skin engaging shaving aid member, of a thermally resilient sensate, the thermally resilient sensate comprising

N-[4-(cyanomethyl)phenyl]-(1R,2S,5R)-2-isopropyl-5-methylcyclohexanecarboxamide of formula:

and

c. from about 15% to about 35%, by weight of the skin engaging shaving aid member, of a water insoluble polymer.

2. The skin engaging shaving aid member of claim 1 , further comprising an optional cooling agent selected from the group consisting of: L-menthol; p-menthane-3,8-diol; Isopulegol; Menthoxypropane-1,2,-diol; Curcumin; Menthyl Lactate; Gingerol; Icilin; Tea Tree Oil; Methyl Salicylate; Camphor; Peppermint Oil; N-Ethyl-p-menthane-3-carboxamide; Ethyl 3-(p-menthane-3-carboxamido)acetate; 2-Isopropyl-N,2,3-trimethylbutyramide; Menthone glycerol ketal, Menthone Glyerine Acetal; and mixtures thereof.

3. The skin engaging shaving aid member of claim 2 , wherein said optional cooling agent is a mixture of L-menthol and menthyl lactate in a ratio of weight in the range of 1:4 to 4:1.

4. The skin engaging shaving aid member of claim 1 , further comprising an encapsulated active present at a level of from about 0.01% to about 50% by weight of the skin engaging shaving aid member.

5. The skin engaging shaving aid member of claim 1 , wherein the water soluble polymer comprises at least one of: a polyethylene oxide, polyvinyl pyrrolidone, polyacrylamide, polyhydroxymethacrylate, polyvinyl imidazoline, polyethylene glycol, polyvinyl alcohol, polyhydroxyethymethacrylate, and silicone polymer.

6. The skin engaging shaving aid member of claim 1 , wherein said water insoluble polymer comprises at least one of: polyethylene, polypropylene, polystyrene, high impact polystyrene, butadiene styrene copolymer, polyacetal, acrylonitrile-butadiene styrene copolymer, and ethylene vinyl acetate copolymer.

7. The skin engaging shaving aid member of claim 1 , wherein said matrix further comprises a block polymer selected from the group consisting of: a di-block copolymer, a tri-block copolymer, a multi-block copolymer, a radial block copolymer, a random block copolymer, and mixtures thereof.

8. The skin engaging member of claim 1 , wherein said water soluble polymer comprises polyethylene oxide.

9. A shaving device comprising:

a. a cartridge;

b. one or more elongated edges positioned on said cartridge; and

c. the skin engaging shaving aid member of claim 1 positioned on said cartridge.
