Definitions

  • TITLE Composition comprising a polyol and at least one polyglyceryl ester
  • the present invention relates to a composition, preferably a cosmetic composition, comprising a polyol and at least one specific polyglyceryl ester, said composition being substantially free of polysaccharide comprising rhamnose and/or fucose, and said composition being substantially free of oil, or having a turbidity equal to or greater than 150 NTU, or comprising PEG-100 stearate. It also relates to a composition, preferably a cosmetic composition, comprising a polyol, at least one specific polyglyceryl ester, and at least one stearic acid and polyethylene glycol ester including 100 ethylene oxide units, said composition being substantially free of polysaccharide comprising rhamnose and/or fucose.
  • the skin is a tissue in which cells are contiguous and firmly attached to each other. Skin tissue forms an external coating comprising sebaceous or sudoriferous glands, and hair follicles.
  • the skin, and particularly the scalp, are continuously renewed epithelia. Renewal, or desquamation, is a coordinated and finely regulated process leading to the elimination of surface cells, insensibly and invisibly.
  • the human skin is composed of two compartments, namely a surface compartment (the epidermis) and a deep compartment (the dermis).
  • the epidermis is conventionally divided into a base layer of keratinocytes forming a germinative layer of the epidermis, a layer called the spinous layer composed of several layers of polyhedric cells arranged on the germinative layers, one to three layers called the stratum granulosum composed of flattened cells containing distinct cytoplasmic inclusions, the keratohyalin grains and finally, a set of upper layers called corneal layers (or stratum corneum), composed of keratinocytes at the terminal stage of their differentiation called corneocytes.
  • corneal layers or stratum corneum
  • Corneocytes are anucleate cells composed principally of a fibrous material containing cytokeratins, surrounded by a corneal envelope. There is permanent production of new keratinocytes to compensate for the continuous loss of epidermal cells in the stratum corneum according to a mechanism called desquamation.
  • fragility of the skin barrier can occur in the presence of external aggression such as irritants (detergents, acids, bases, oxidants, reducing agents, concentrated solvents, noxious gases or fumes), mechanical actions (friction, shocks, abrasion, surface tearing, projection of dust, particles, shaving or epilation), thermal or climatic unbalances (cold, dryness, radiation), xenobiotic unbalances (undesirable micro-organisms, allergens) or internal aggressions of the psychological stress type.
  • irritants detergents, acids, bases, oxidants, reducing agents, concentrated solvents, noxious gases or fumes
  • mechanical actions frequency, shocks, abrasion, surface tearing, projection of dust, particles, shaving or epilation
  • thermal or climatic unbalances cold, dryness, radiation
  • xenobiotic unbalances undesirable micro-organisms, allergens
  • One of the critical steps in the terminal differentiation process of the stratum corneum is cross-linking of proteic precursors of the cornified envelope. This phenomenon plays an essential role in the development and maintenance of skin cohesion and physical properties of the skin such as the barrier function.
  • the cornified envelope is an essential component of corneocytes.
  • Maturing of the cornified envelope from the deep layers to surface layers of the stratum corneum can be characterized by morphological and biophysical or mechanical parameters.
  • Hydrating agents conventionally used such as moisturizers, hydrating polymers or fatty bodies such as petroleum jelly, temporarily modify the surface properties of the skin.
  • These active agents can increase the mechanical suppleness of the stratum corneum, increase its state of hydration and/or improve the microrelief of the skin by the formation of a surface film on the skin. In general, these effects are not remanent in time and only last for a few hours. Furthermore, after the skin has been cleaned, these active agents are eliminated and the effect of increased mechanical suppleness of the skin, improved skin texture or optical properties of the skin disappear.
  • compositions that confer a plumping effect and/or a bouncy appearance on the skin are also a need for compositions that confer a plumping effect and/or a bouncy appearance on the skin.
  • Boncy appearance means an effect of remodelling the skin. The skin is smoother and has a more fleshy appearance, that remains even after pressing on the skin with a finger.
  • the inventors have now discovered that the association of a polyol and at least one polyglyceryl ester can satisfactorily increase the suppleness of the skin and confer a plumping effect and a bouncy appearance on it.
