Definitions

  • the present invention relates to low viscosity W / O emulsions containing one or more glucosylglycerides and one or more electrolytes.
  • the present invention relates to active ingredients and cosmetic or dermatological preparations containing such drug combinations.
  • the present invention relates to cosmetic preparations with a content of substances which increase the skin moisture.
  • the outermost layer of the epidermis, the stratum corneum (horny layer), is of particular importance as an important barrier layer, inter alia. for protection against environmental influences and dehydration.
  • the horny layer is constantly worn in contact with the environment and must therefore be renewed continuously.
  • a skin model widely used today in the art understands the stratum corneum as a two-component system, similar to a brick wall (brick-mortar model).
  • the corneocytes horny cells
  • the complex composite lipid membrane in the intercellular spaces corresponds to the mortar.
  • the epidermal lipids In addition to their barrier effect against external chemical and physical influences, the epidermal lipids also contribute to the cohesion of the horny layer and have an influence on the skin smoothness. In contrast to the sebaceous gland lipids, which do not form a closed film on the skin, the epidermal lipids are distributed over the entire horny layer.
  • the extremely complex interaction of the moisture-binding substances and the lipids of the upper skin layers is very important for the regulation of skin moisture. Therefore, cosmetics usually contain, in addition to balanced lipid mixtures and water, water-binding substances. These include polyols such as glycerin, sorbitol and xylitol, ethoxylated polyols and hydrolyzed proteins.
  • Natural Moisturizing Factor NMF
  • urea e.g glucose
  • amino acids e.g serine
  • W / O emulsions must be stabilized with electrolytes to ensure “salting out” of hydrophilic emulsifier constituents.
  • hydrophilic a W / O emulsifier (HLB value greater than 4), the more salt must be used.
  • a hydrophilic W / O emulsifier ensures that the viscosity of the water-in-oil emulsion can be set low, thereby achieving a better spreadability and skin absorption. This causes rapid instability of the W / O emulsion, so that previous W / O emulsions are always formulated with emulsifiers which have an HLB of less than 8.
  • concentrations of all components of a cosmetic or dermatological preparations are given in such units as% by weight,% by mole and the like. Because of their more or less pronounced dissociation into cations and anions, often in several dissociation stages, it seems more appropriate for the description of the present invention and its technical background to start from the ionic strength of a given electrolyte in its solution.
  • the ionic strength I of an electrolyte solution is defined as i
  • Cj represent the concentrations of the individual types of ions (in mol / l) and z, their charge numbers.
  • the physical unit of ionic strength is that of a concentration (mol / l).
  • the salts with the following anions chlorides, inorganic oxo element anions, of these in particular silicates, sulfates, carbonates, phosphates, borates and aluminates.
  • Electrolytes based on organic anions are also advantageous, for example lactates, acetates, benzoates, propionates, tartrates, citrates, amino acids and their salts and others. Comparable effects can also be achieved by ethylenediaminetetraacetic acid and its salts, as well as imidodisuccinic acid and its salts.
  • ammonium alkylammonium, alkali metal, alkaline earth metal, calcium, magnesium, iron cupfer aluminum or zinc ions.
  • cosmetically acceptable electrolytes should be used in cosmetics.
  • the electrolyte or electrolytes are furthermore advantageously selected from the group
  • water-soluble UV filter substances in particular those which carry on their molecular skeleton one or more sulfonic acid groups or sulfonate groups:
