Definitions

  • the present invention relates to skin- and hair-care cosmetic compositions.
  • cosmetic compositions in the form of aqueous gels or lotions which provide improved visual clarity, moisturization, skin feel and skin care benefits, reduced tack and residue characteristics together with excellent rub-in and absorption characteristics.
  • 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 25nm protein bundles surrounded by 8nm thick layers.
  • Anionic surfactants and organic solvents typically penetrate the stratum corneum membrane and, by delipidization (i.e. removal of the lipids from the stratum corneum), destroy its integrity. This destruction of the skin surface topography leads to a rough feel and may eventually permit the surfactant or solvent to interact with the keratin, creating irritation.
  • Hair consists of many of the same constituents as the stratum corneum.
  • the outermost region of cells forms a rather thick chemically resistant protective coating enclosing the hair fibre which is called the cuticle.
  • the surface of the cuticle is covered with a thin layer called the epicuticle which is thought to contain lipids and protein.
  • the cuticle envelopes the cortex cells which comprise the major part of the fibre mass. Keratinization takes place in the cortex to build stability into the hair structure.
  • compositions which will assist the stratum corneum and hair cuticle in maintaining their barrier and water-retention functions at optimum performance in spite of deleterious interactions which the skin and hair may encounter in washing, work, and recreation.
  • water-soluble polyglycerylmethacrylate lubricants have been incorporated into skin and hair compositions in an attempt to reduce the above problems.
  • These compositions have provided improvements in moisturisation, absorption, skin feel, residue and skin care characteristics compared with conventional cosmetic cream and lotion compositions. They have, however, also suffered negatives such as tackiness, especially when large concentrations of the lubricant are employed.
  • microemulsified silicone oil has been added to polyglycerylmethacrylate lubricants. Although this has led to a reduction of tackiness, the visual clarity of the final aqueous compositions is poor. In general, the compositions appear to be opalescent, which some consumers find undesirable.
  • the present invention therefore provides skin- and hair-care cosmetic compositions which provide improvements in moisturization, absorption, residue, skin feel and skin care characteristics and which in particular provide improvements in tackiness while at the same time maintaining excellent visual clarity.

Abstract

Une composition pour les soins de la peau ou des cheveux se présente sous la forme d'un gel aqueux composé d'un lubrifiant pré-émulsifié à base de silicone/polyglycérylméthacrylate, d'un agent gélifiant hydrophile et d'un agent tensioactif non ionique alcoxylé dont l'indice moyen de l'équilibre hydrophile-lipophile en poids est d'au moins 12, ou un humectant à indice de réfraction compris entre 1.4 et 1.5. Grâce auxdites compositions on obtient des améliorations en ce qui concerne la clarté, l'hygrométrie et le toucher de la peau, ainsi que d'autres avantages pour le soin de la peau, lesdites compositions étant moins collantes et présentant moins d'éléments résiduels après leur application. De plus, les caractéristiques d'application par massage et d'absorption de ladite composition sont excellentes.
