Abstract: The lubricity of any shaving preparation is enhanced by providing an emollient oil and a thermoplastic polymeric elastomer additive in an amount effective to increase its lubricity. Specific shaving preparations suitable for application to human or animal skin may comprise at least 5% by weight of an emollient oil, and a thermoplastic polymeric elastomer additive in a ratio of emollient oil to additive of between about 5:1 and 20:1, and preferably in a ratio of between about 8:1 and 10:1. Shaving creams generally contain 5-30% of an emollient oil, a thermoplastic polymeric elastomer additive present in a ratio of emollient oil to additive of between about 5:1 and 20:1, and at least 5% by weight of soap, detergent or a combination thereof.
