| abstract |
The invention describes the use of a nano-dispersion comprising (a) a membrane-forming molecule, (b) a coemulsifier, (c) a lipophilic component, and (d) an oxidation-sensitive water soluble ingredient in final formulations Cosmetics, the nano-dispersion can be obtained by (a) mixing the components (a), (b) and (c) until a homogeneous liquid is obtained (what is known as the nano-dispersion pre-phase), and ( ß) add the water or the aqueous phase (discontinuous phase) containing the water soluble ingredient and optionally the non-aqueous polar organic solvent to the liquid obtained in step (a) Component (d) is preferably ascorbic acid or vitamin C. |
