- b) a water insoluble thermoplastic polymeric elastomer additive present in a ratio of emollient oil to additive of between about 5:1 and 20:1, and
- c) at least 5% by weight of soap, detergent or a combination thereof.
- 4. A shaving cream preparation of claim 3 comprising
- a) 5-30% .of an emollient oil,
- b) a water insoluble thermoplastic polymeric elastomer additive present in a ratio of emollient oil to additive of between about 5:1 and 20:1, and
- c) between 10 and 50% by weight of soap, detergent or a combination thereof.
- 5. A shaving cream preparation of claim 4 comprising
- a) 5-30% of an emollient oil,
- b) a water insoluble thermoplastic polymeric elastomer additive present in a ratio of emollient oil to additive of between about 5:1 and 20:1, and
- c) between 15 and 30% by weight of soap, detergent or a combination thereof.
- 6. The shaving preparation of claim 1, wherein said water insoluble thermoplastic polymeric elastomer additive is a multi-block copolymer comprising block A and block B; wherein block A is made from a monomer wherein the corresponding homopolymer has a T.sub.g less than about 10.degree. C., and block B is made from a monomer wherein the corresponding homopolymer has a T.sub.g greater than about 90.degree. C.; said block B is about 15-40% by weight of the total thermoplastic polymeric elastomer additive.
- 7. The shaving preparation of claim 6, wherein said water insoluble thermoplastic polymeric elastomer additive is a two-block copolymer.
- 8. The shaving preparation of claim 7, wherein said water insoluble thermoplastic polymeric elastomer additive is a styrene-butadiene copolymer.
- 9. The shaving preparation of claim 6, wherein said water insoluble thermoplastic polymeric elastomer additive is a tri-block copolymer.
- 10. The shaving preparation of claim 9, wherein said water insoluble thermoplastic polymeric elastomer additive is a styrene-isoprene-styrene copolymer.
- 11. The shaving preparation of claim 9, wherein said water insoluble thermoplastic polymeric elastomer additive is a styrene-butadiene-styrene copolymer.
- 12. The shaving preparation of claim 9, wherein said water insoluble thermoplastic polymeric elastomer additive is a styrene-ethylene/butylene-styrene copolymer.
- 13. The shaving preparation of claim 3, wherein said water insoluble thermoplastic polymeric elastomer additive comprises between about 1 and 5% by weight of the total preparation.
- 14. The shaving preparation of claim 13, wherein said water insoluble thermoplastic polymeric elastomer additive comprises between about 2 and 4% by weight of the total preparation.
- 15. The shaving preparation of claim 3, wherein said soap is a mixture of salts of stearic acid.
- 16. The shaving preparation of claim 1, wherein said preparation has an initial Inclined Plane Slipperiness Test Angle that is less than about 70% of the Inclined Plane Slipperiness Test Angle of the same composition not containing water insoluble thermoplastic polymeric elastomer additive.
- 17. The shaving preparation of claim 1, wherein said preparation has an Inclined Plane Slipperiness Test Angle after 4 minutes that is not more than about 10% higher than the Initial Inclined Plane Slipperiness Test Angle.
- 18. A method of preparing a hairy area of an animal or human for shaving comprising applying the shaving preparation of claim 1 to the hairy area in an amount effective to lubricate and moisturize the area to be shaved.
