Definitions

  • the present application describes aerosol-sprayable cosmetic water-in-oil emulsions. Another object of this application is a method using appropriate emulsions.
  • An aerosol is a disperse system in which a solid or a liquid is very finely dispersed in a gas.
  • the aerosol is usually only when using a suitable spray system by spraying solutions, emulsions or suspensions self-produced, including, for example, spray cans can be used, in which a liquefied compressed gas serves as a propellant gas.
  • spray cans can be used, in which a liquefied compressed gas serves as a propellant gas.
  • the pressure valve is opened, the propellant preparation mixture escapes through a fine nozzle which evaporates the propellant and leaves the finely distributed spray material as an aerosol.
  • a technically important area for the application of cosmetic aerosol sprays is the field of deodorant cosmetic products.
  • Common deodorant spray compositions are often present as anhydrous ethanolic solutions of the deodorizing agent.
  • a disadvantage of these ethanolic solutions is a skin irritant effect in appropriately predisposed persons with sensitive skin. Even on skin mechanically irritated by shaving, the application of common ethanolic solutions leads to a very unpleasant burning sensation.
  • a further disadvantage of ethanolic solutions is that the incorporation of water-containing or water-soluble active substances, in particular antiperspirant or deodorant active ingredients or hair growth inhibiting active ingredients which are not soluble in ethanol, is not or only to a very limited extent possible.

  • German Patent Application DE 10 2006 062 499 A1 (Henkel) discloses a W / O emulsion suitable as an aerosol spray.
  • the emulsions disclosed in this application however contain cyclomethicones. Cyclomethicones have excellent performance properties, in particular with regard to emulsion stability, and for this reason are used in cosmetics, in particular in antiperspirants.
  • the emulsion should also be characterized by a low tendency to corrosion when stored in a metallic spray can and by a good cosmetic, especially antiperspirant effect and low residue formation during application.
