Abstract

A skin engaging member suitable for use in a hair removal device, said skin engaging member comprising ethyl vinyl acetate having a low level of vinyl acetate and a water soluble polymer.

Claims (26)

1 . A hair removal device comprising at least one blade, and a skin engaging member comprising:

a. about 50% to about 78% of a water-soluble polymer comprising polyethylene oxide with an average mol wt of about 2 million to 10 million Da;

b. about 26% to about 40% an ethylene vinyl acetate by weight of the skin engaging member; and

c. a total vinyl acetate level of from about 0.2% up to 7.5% by weight of the skin engaging member.

2 . A hair removal device comprising at least one blade, and a skin engaging member comprising:

a. about 50% to about 78% of a water-soluble polymer;

b. about 30% to about 40% an ethylene vinyl acetate by weight of the skin engaging member; and

c. a total vinyl acetate level of from about 0.2% up to 7.5% by weight of the skin engaging member.

3 . The hair removal device of claim 1 , wherein said water-soluble polymer further comprises a second water-soluble polymer other than polyethylene oxide.

4 . The hair removal device of claim 1 , wherein the level of ethylene vinyl acetate is from about 26% to about 30%.

5 . The hair removal device of claim 1 , wherein the total vinyl acetate level is about 2% to about 5%,

6 . The hair removal device of claim 5 , wherein the total vinyl acetate level is below about 4%.

7 . A hair removal device comprising at least one blade, and a skin engaging member comprising:

a. a water-soluble polymer comprising polyethylene oxide with an average mol wt of over 2 million Da, up to about 5 million Da;

b. about 26% to about 40% an ethylene vinyl acetate by weight of the skin engaging member; and

c. a total vinyl acetate level of from about 0.2% up to 7.5% by weight of the skin engaging member.

8 . The hair removal device according to claim 7 , wherein the water-soluble polymer is at a level of about 50% to about 78% of said skin engaging member.

9 . The hair removal device according to claim 7 , further comprising a fragrance.

10 . The hair removal device according to claim 7 , further comprising a second water soluble polymer selected from the group consisting of: polyvinyl pyrrolidone, polyacrylamide, polyhydroxymethacrylate, polyvinyl imidazoline, polyethylene glycol, polyvinyl alcohol, polyhydroxyethymethacrylate, silicone polymers, and mixtures thereof.

11 . The hair removal device according to claim 7 , further comprising a second water soluble polymer comprising polyethylene glycol.

12 . The hair removal device according to claim 7 , further comprising a second water-insoluble polymer selected from the group consisting of polyethylene, polypropylene, polystyrene, butadiene-styrene copolymer (e.g. medium and high impact polystyrene), polyacetal, acrylonitrile-butadiene-styrene copolymer, ethylene vinyl acetate copolymer, polyurethane, and blends thereof

13 . The hair removal device according to claim 7 , further comprising a second water-insoluble polymer selected from the group consisting of:

polypropylene/polystyrene blend and polystyrene/impact polystyrene blends.

14 . The hair removal device according to claim 7 , wherein the level of ethylene vinyl acetate is from about 26% to about 30%.

15 . The hair removal device according to claim 7 , wherein the total vinyl acetate level is about 2% to about 5%,

16 . The hair removal device according to claim 15 , wherein the total vinyl acetate level is about 2.5% to about 4%.
