Definitions

  • the present invention relates to a cosmetic preparation containing scleroglucan.
  • Emulsions are generally understood to mean heterogeneous systems which consist of two liquids which are immiscible or only partially miscible with one another, which are usually referred to as phases and in which one of the two liquids is dispersed in the other liquid in the form of very fine droplets. Externally and with the naked eye, emulsions appear homogeneous.
  • the two liquids are water and oil and if oil droplets are finely distributed in water, then it is an oil-in-water emulsion (O / W emulsion, e.g. milk).
  • O / W emulsion oil-in-water emulsion
  • the basic character of an O / W emulsion is shaped by the water.
  • W / O emulsion water-in-oil emulsion, e.g. butter
  • so-called emulsifiers are added to the emulsions.
  • Emulsifiers are usually molecules with a polar, hydrophilic structural element and a non-polar, lipophilic structural element.
  • a so-called HLB value (a dimensionless number between 0 and 20) is assigned to each emulsifier, which indicates whether the water or oil solubility is preferred. Numbers under 8 indicate oil-soluble, hydrophobic emulsifiers, numbers over 8 indicate water-soluble, hydrophilic emulsifiers.
  • the water phase is combined with the lipid phase (oil phase) with stirring, the droplets of the inner phase of the emulsion having to be broken down to a size of less than 10 ⁇ m so that the emulsion becomes stable.
  • O / W emulsions with hydrophilic emulsifiers (emulsifiers with an HLB value of greater than / equal to 8)
  • the problem often arises that when predominantly medium-polar to polar lipids are used in the oil phase (i.e. lipids with an interfacial tension against water of less than 30 mN / m) an undesirable phase reversal can take place.
  • O / W emulsions tend to reverse phase during storage; H. the preparations are often not particularly stable in storage.
  • the object is surprisingly achieved by cosmetic oil-in-water emulsions (O / W emulsions) containing, in addition to a water phase, one or more oil phases dispersed therein as well
  • Scleroglucan is released into the surrounding medium as a microbial exopolysaccharide by fungal species of the genus Sclerotium (Basidiomycota, Agariomycetes). Sclerotium delphinii for example is a major pest of plants. Scleroglucan is also known as Sclerotium Gum (INCI: Sclerotium Gum).
  • Scleroglucan is a (1—>3;1—> 6) - ⁇ -D-glucan. Its mean molar mass is about 5.7 * 10 6 g / mol, its average degree of polymerization about 35,000.
  • Scleroglucan consists of a linear (1—> 3) - ⁇ -D-glucan chain (O d HioO d OQHIOOd) ⁇ , on which statistically every third glucose unit with a single (1—> 6) - ⁇ -D- Glcp residue is branched.
  • Scleroglucan is readily soluble in water and can be used as a thickener.
  • the use of scleroglucan in cosmetic emulsions is known per se to the person skilled in the art, but the prior art could not point the way to the present invention.
  • DE 10 2014 015 554 discloses the use of scleroglucan in UV filters containing cosmetic preparations to reduce the contamination and / or discoloration of textiles caused by the UV filters in the preparation.
  • EP 1 132 076 describes thickened hair compositions containing scleroglucan.
  • the emulsion according to the invention is characterized in that the content of scleroglucan in the emulsion is from 0.001 to 5.0% by weight and preferably between 0.01 and 1.5% by weight, particularly preferably between 0, 1 and
  • the emulsion contains one or more oil-in-water emulsifiers (O / W emulsifiers) in a total concentration of 0.05 to 5.0% by weight and preferably in a total concentration of 2.0 to 4.0% by weight, based in each case on the total weight of the emulsion.
  • O / W emulsifiers oil-in-water emulsifiers

  • the emulsion according to the invention is characterized in that hydrophilic emulsifiers with an HLB value of greater than or equal to 8 are used as O / W emulsifiers.
  • HLB value of emulsifiers can be found in the usual standard works (e.g. Fiedler, Lexicon of Auxiliaries for Pharmacy, Cosmetics and Neighboring Areas, Editio Cantor Verlag, Aulendorf).
