Definitions

• the present invention relates to cleansing compositions.
• foam-producing personal cleansing compositions suitable for simultaneously cleansing and conditioning the skin and/or the hair and which may be used, for example, in the form of foam bath preparations, shower products, skin cleansers, hand, face and body cleansers, shampoos, etc.
• Foaming cosmetic compositions must satisfy a number of criteria including cleansing power, foaming properties, mildness/low irritancy and physical stability.
• Oil-in- water emulsion systems typical of foaming cosmetic compositions represent a particular challenge with respect to stability and viscosity. While on one hand it is possible to ultilise agents specifically to induce appropriate viscosity, care must be taken to ensure these agents work to maintain that viscosity over time.
• Certain fatty acids are known to be effective in the achievement of matrix viscosity. However this is generally dependant upon the fatty acid forming stable complexes.
• Skin is made up of several layers of cells which coat and protect the keratin and collagen fibrous proteins that form the skeleton of its structure.
• the outermost of these layers referred to as the stratum corneum, is known to be composed of 250 A protein bundles surrounded by 80 A thick layers. Hair similarly has a protective outer coating enclosing the hair. fibre which is called the cuticle.
• Anionic surfactants can penetrate the stratum corneum membrane and the cuticle and, by delipidization destroy membrane integrity. This interference with skin and hair protective membranes can lead to a rough skin feel and eye irritation and may eventually permit the surfactant to interact with the keratin and hair proteins creating irritation and loss of barrier and water retention functions.
• Ideal cosmetic cleansers should cleanse the skin or hair gently, without defatting and/or drying the hair and skin and without irritating the ocular mucosae or leaving skin taut after frequent use. Most lathering soaps, shower and bath products, shampoos and bars fail in this respect.
