The present invention produces advanced cosmetics by combining high dispersion ratio (HIPR) emollient / water emulsions with partial cosmetic formulations that typically include water, colorants, fragrances, rheology modifiers or pH adjusters or combinations thereof. Process. The invention also includes in particular two HIPR emollient / water emulsions, namely HIPR silicone elastomer / water emulsion and HIPR sunscreen / water emulsion and their water-diluted dispersions. The use of cosmetic emollient HIPR emulsions, in part, is the long-term stability of HIPR (longer than 1 year) and the low amount of water in the emulsion (typically less than 20 volumes on an emollient and water volume basis). Provides a simple and flexible formulation method for cosmetics. HIPR sunscreen / water emulsions can be formulated into advanced cosmetics to obtain improved solar protection factor (SPF) and critical wavelength. |
