Abstract
The invention relates to the use of multiphase compositions comprising a) at least one oil phase and b) at least one aqueous phase for foaming from foam dispensers. The compositions are preferably cosmetic compositions, particularly preferably sunscreen compositions.
Claims29
A method for dispensing a foam comprising foaming from a foam dispenser a multiphase composition comprising
- a) at least one oil phase and
- b) at least one aqueous phase comprising a foam-boosting surfactant,
- wherein said multiphase composition is free of emulsifier.
The method of claim 12, wherein the electrolytes are alkali metal salts and/or alkaline earth metal salts.
The method of claim 15, wherein the cosmetic composition comprises sunscreen compositions.
A method of preparing foam, which comprises foaming a multiphase composition comprising
- a) at least one oil phase and
- b) at least one aqueous phase comprising a foam-boosting surfactant.
- with a foam dispenser, wherein said multiphase composition is free of emulsifier.
A foam dispenser comprising a pump foamer containing at least one multiphase composition which comprises
- a) at least one oil phase and
- b) at least one aqueous phase comprising a foam-boosting surfactant,
- wherein said multiphase composition is free of emulsifier.
A method for producing foam from a multiphase composition, said method comprising
- a) mechanically mixing the multiphase composition having at least two phases and comprising least one oil phase and at least one aqueous phase comprising a foam-boosting surfactant, said multiphase composition being free of emulsifier, to provide a phase mixture;
- b) foaming the phase mixture without a propellant in a foamer to generate the foam.
