Definitions

  • the present invention relates to a cosmetic preparation in the form of an O / W emulsion or ethanolic solution containing a) at least one UV filter from the group of triazine derivatives b) caprylic / capric acid triglyceride (INCI: Caprylic / Capric triglyceride) c) one or more W / O emulsifiers from the group of polyglyceryl compounds.
  • UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as Annex 6 of the Cosmetics Ordinance.
  • UV filters based on triazine derivatives In order to achieve high sun protection factors, the use of UV filters based on triazine derivatives is almost indispensable. In order to keep these poorly soluble compounds in solution or to get them in solution at all in the recipe, a number of oil components are used. In the past, the use of UV filters that are liquid at room temperature, such as octocrylene or 4-methoxycinnamic acid 2-ethylhexyl ester (INCI octyl methoxycinnamate), has proven to be particularly ingenious.
  • sunscreens are the synthetic polymers, which, for example, contribute to the water resistance of the product as film formers such as vinylpyrrolidone / hexadecene copolymers or such as gel formers based on polyacrylates (polyacrylates, cross-linked acrylate / C10-C30 alkyl acrylate polymers) ensure the viscosity and stability of the preparation. Some scientists assume that these substances are more difficult to biodegrade. For others, these substances simply count as “microplastics”.
