Abstract

Disclosed is a shaving preparation imparting durable lubricity. The shaving preparation has one or more silicone polyethers and one or more water-soluble polymers that associate with the one or more silicone polyethers in aqueous solution. The lubricity of the shaving preparation can be reactivated by wetting the skin after shaving without applying an additional amount of the shaving preparation. Also disclosed is a method for using the shaving preparation.

Claims (27)

1. A method of removing hair from the skin comprising:

A) applying to said skin a shaving preparation comprising

one or more silicone polyethers in an amount of about 0.001 weight percent (wt %) to about 50.0 wt % of the shaving preparation;

one or more water-soluble polymers that associate with the one or more silicone polyethers in an amount of about 0.001 wt % to about 10.0 wt % of the shaving preparation;

one or more anionic surfactants selected from the group consisting of sodium dodecyl sulfate, ammonium lauryl sulfate, and sodium laureth sulfate; and

water in an amount of about 0.5 wt % to about 95.0 wt % of the shaving preparation;

B) moving a shaving implement on the surface of the skin to shave the hair,

C) wetting the shaved area of the skin with water without applying more of said shaving preparation; and

D) moving the shaving implement on the surface of the shaved area of the skin a second time to shave additional hair;

wherein the lubricity of said shaving preparation on the skin is reactivated by said wetting step.

2. The method of claim 1 , wherein the one or more silicone polyethers are selected from the group consisting of polyethylene glycol-12 dimethicone and dimethicone copolyol.

3. The method of claim 1 , wherein the one or more water-soluble polymers that associate with the one or more silicone polyethers is a linear homopolymer derived from ethylene oxide.

4. The method of claim 1 , wherein the one or more silicone polyethers are from about 0.25 wt % to about 5.0 wt % of the shaving preparation.

5. The method of claim 1 , wherein the one or more water-soluble polymers that associate with the one or more silicone polyethers are from about 0.05 wt % to about 1.0 wt % of the shaving preparation.

6. The method of claim 1 , wherein the ratio of the one or more silicone polyethers to the one or more water-soluble polymers that associates with the silicone polyethers, as weight percents of the shaving preparation, is from about 5:1 to about 10:1.

7. The method of claim 6 , wherein the ratio of the one or more silicone polyethers to the amount of the one or more water-soluble polymers that associate with the silicone polyethers, as weight percents of the shaving preparation, is about 10:1.

8. The method of claim 1 , wherein said shaving preparation further comprises at least one of: sodium laureth sulfate, cocamidopropyl betaine, glycerin, and one or more water-soluble polymers that do not associate with the one or more silicone polyethers.

9. The method of claim 8 , wherein

the sodium laureth sulfate is about 0.1 wt % to about 5.0 wt % of the shaving preparation;

the cocamidopropyl betaine is about 0.1 wt % to about 5.0 wt % of the shaving preparation;

the glycerin is about 0.1 wt % to about 5.0 wt % of the shaving preparation; and

the one or more water-soluble polymers that do not associate with the one or more silicone polyethers are about 0.1 wt % to about 3.0 wt % of the shaving preparation.

10. The method of claim 8 , wherein the one or more water-soluble polymers that do not associate with the silicone polyethers are selected from the group consisting of acrylates, C 10 -C 30 alkyl acrylate crosspolymers, xanthan gum, hydroxyethyl cellulose, and carboxymethyl cellulose.

11. The method of claim 1 , wherein the shaving preparation is in a form selected from the group consisting of a gel, foam, liquid or cream.

12. The method of claim 11 , wherein said shaving preparation is in the form of a gel.

13. The method of claim 12 , wherein the shaving preparation is not aerosolized.

14. The method of claim 3 , wherein the one or more water-soluble polymers is selected from the group consisting of polyethylene glycol-14M, polyethylene glycol-90M, polyethylene glycol-7M, and polyethylene glycol-23M.
