Abstract
Water-based emulsifier wax gels are provided that include skin-identical sphingolipids The present invention also provides a process for the preparation of such gels, the use of such gels for the preparation of oil-in-water emulsions, and the resulting emulsions that contain the inventive gels.
Claims11
A water-based emulsifier wax gel comprising:
- a) 1 to 4% by weight of a skin-identical free sphingoid base,
- b) 0.5 to 6.0% by weight of at least one nonionic or anionic emulsifier,
- c) 1 to 8% by weight of at least one wax-like consistency-imparting agent, and
- d) 80 to 98% by weight water.
A process for the preparation of emulsifier wax gels comprising melting a skin-identical free sphingoid base with at least one non-ionic or anionic emulsifier, at least one consistency-imparting agent at a temperature which is increased relative to room temperature, bringing the mixture into contact with water, homogenizing the mixture and then cooling the mixture to room temperature with stirring.
An oil-in-water emulsion comprising a water-based emulsifier wax gel which comprises a skin-identical free sphingoid base, at least one nonionic or anionic emulsifier, at least one wax-like consistency-imparting agent, and water.
