  • the present invention relates to a cosmetic emulsion with cationic emulsifier and siloxane elastomer.
  • silicone compounds and powder raw materials are to be mentioned here, as they the sticky feeling of For example, glycerol or the oily / greasy appearance of many lipids or UV filters can mask. It is found in products reinforced the use of silicone elastomers, which are different crosslinked and / or modified polydimethylsiloxanes, which are usually present in a medium swollen as a gel. This medium is preferably a low-viscosity, preferably volatile silicone.
  • This class of raw material provides a powdery / dry, velvety / silky feel on the skin after dispensing and may, depending on the type of formulation, mask oily / greasy and / or sticky raw materials.
  • siloxane elastomer having the following structure:
  • R 2 hydrogen
  • R, R 'and R " alkyl groups having 1 to 6 C atoms
  • reaction is carried out until a gel is formed by cross-linking by the addition of Si-H to the double bonds of the alpha, omega-diene.
  • the skin feeling experienced when applying this preparation according to the invention is evaluated by the users as follows: The preparation absorbs more quickly into the skin, leaving a powdery-velvety feeling on the skin, with the impression that in the skin Compared to other preparations, only little residue on the skin remains.
  • cosmetic preparation means the emulsion according to the invention.
  • R 3 is chosen from polyethers, pentylene, hexylene, heptylene, octylene, nonylene, decylene, dodecylene, tetradecylene and mixtures thereof.

  • each R 1 is independently a monovalent hydrocarbon group of 1 to 30 carbon atoms, a is 265 to 2,000 and d is 1 to 250
  • an additional second ⁇ Si H-containing polysiloxane is present, which is selected from HR 1 2 SiO (R 1 2SiO) e SiR 1 2H,

  • Example 1 and Comparative Example 1 differed by the emulsifier. While example 1 contains the cationic emulsifier according to the invention, comparative example 1 is based on the nonionic emulsifier polyglyceryl-3 methylglucose distearate. It can be clearly seen that both products move in at the same speed, but the residue when using the cationic emulsifier is less perceptible and the skin feeling is described as powdery and velvety / silky.
  • Example 1 and Comparative Example 2 differ by the silicone polymer. While Example 1 contains a silicone elastomer according to the invention, Comparative Example 2 uses a linear silicone. It can be clearly seen that the formula with silicone elastomer retracts faster, leaves less residue and the skin feeling is described as powdery and velvety / silky.
