Definitions

  • the present invention relates to cleansing compositions.
  • mild personal cleansing compositions which display improved product stability and in combination with good rinse feel, good skin feel attributes, and foaming properties which are 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.
  • Mild cosmetic compositions must satisfy a number of criteria including cleansing power, foaming properties and mildness/low irritancy/good feel with respect to the skin, hair and the ocular mucosae.
  • Skin is made up of several layers of cells which coat and protect the underlying tissue. The keratin and collagen fibrous proteins that form the skeleton of its structure. The outermost of these layers is referred to as the stratum corneum.
  • 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 and loss of barrier and water retention functions. 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 trigger immune response creating irritation.
  • 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.
  • Certain synthetic surfactants are known to be mild.
  • a major drawback of some mild synthetic surfactant systems when formulated for shampooing or personal cleansing is that they have what can be described as a "slippy" or “non-draggy” rinse feel which is not liked by some consumers.
  • the use of certain surfactants such as potassium laurate, on the other hand, can yield a "draggy" rinse feel but at the expense of clinical skin mildness.
  • Personal cleansing compositions having a "draggy" rinse feel at the same time as having excellent mildness characteristics are provided by the combination of certain water-insoluble oils, such as certain polyalphaoleftn oils, in combination with a mild, water-soluble surfactant system.
  • Conventional personal cleansing compositions use materials such as Bentone gels and ethylene glycol distearate. Crystalline hydroxyl- containing stabilizer materials such as trihydroxystearin are known for use in liquid skin cleansers.
  • WO 96/25144 discloses stress stable lathering skin cleansing compositions comprising a crystalline, hydroxy-containing stabilizer, lipid skin moisturising agent, surfactant and water.
  • GB-A- 2297975 discloses personal cleansing compositions comprising surfactant, water-insoluble salt of a C14-C22 fatty acid, optionally a cationic or nonionic polymeric skin conditioning agent, trihydroxystearin and water.

  • compositions of the present invention provide an improvement in stability and rheology characteristics while at the same time providing an excellent rinse feel to the skin.
  • liquid cleansing compositions herein comprise water, surfactant, crystalline hydroxy-containing stabilizer and a certain water-insoluble oil which will be described below.
  • rinse feel means the feeling of the skin during the process of rinsing lather from the skin after cleansing with a cleansing composition.
  • the type of rinse feel which is provided by the compositions of the present invention can be described by terms such as a “draggy” rinse feel, a “soap-like” rinse feel and a “non-slippery” or “non-slimy” rinse feel.
  • Such a “draggy”, “soap-like”, “non-slippery” or “non-slimy” rinse feel can be detected by an increase in friction between the hand and skin during the process of rinsing lather from the skin.
