  • Transparent oil-in-water emulsion
    Patent number: 7488471
    Abstract: The present invention relates to transparent or clear emulsions for cosmetic or pharmaceutical use. The transparent emulsions of the present invention comprise an oil phase, containing at least one lipophilic solvent; an aqueous phase; and an emulsifying system containing at least one non-ethoxylated fatty acid ester emulsifier having a hydrophilic-lipophilic balance (“HLB”) from about 11 to about 16. Preferred non-ethoxylated fatty acid ester emulsifiers are sucrose esters, in particular sucrose palmitate and sucrose laurate.
    Type: Grant

  • Mattifying oil-in-water emulsion
    Patent number: 7192599
    Abstract: The present invention relates to cosmetic and pharmaceutical oil-in-water emulsions which have a mattifying effect when applied to the skin. The invention comprises a hydrophilic, non-organically modified magnesium aluminum silicate or a bentonite clay and a polyol in the water phase; and a volatile, skin-compatible, lipophilic solvent and a high melting point lipophilic plasticizer in the oil phase. A preferred surfactant system to stabilize the emulsion includes non-toxic metal alkyl sulfates and/or sucrose esters.
