Definitions

  • the present invention relates to a process for producing an O / W emulsion, characterized in that an O / W emulsion containing a) a lipid phase in a concentration of 20 to 95% by weight, b) one or more water-soluble polymers in one Total concentration of 1 to 80% by weight, based in each case on the total weight of the preparation, and c) one or more UV light protection filters and d) an aqueous phase, in addition to any other cosmetic and / or dermatological active ingredients, auxiliaries and additives, by spray drying and / or freeze drying.
  • the skin is the largest organ in humans. Among its many functions (for example for heat regulation and as a sensory organ), the barrier function that prevents the skin (and ultimately the entire organism) from drying out is probably the most important. At the same time, the skin acts as a protective device against the penetration and absorption of external substances and UV radiation. This barrier function is brought about by the epidermis, which as the outermost layer forms the actual protective cover against the environment. At around a tenth of the total thickness, it is also the thinnest layer of the skin.
  • Emulsions are generally understood to mean heterogeneous systems which consist of two immiscible or only to a limited extent miscible liquids, which are usually referred to as phases and in which one of the two liquids is dispersed in the form of very fine droplets in the other liquid. When viewed externally and with the naked eye, emulsions appear homogeneous.
  • the two liquids are water and oil and 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
