20090148481 | METHOD OF FORMULATING ZINC OXIDE POWDER BLENDS FOR BALANCED UVA/UVB ATTENUATION - Disclosed is a composition that comprises an effective proportion of a first metal oxide powder having a primary particle size and a secondary particle size selected for the first metal oxide powder to attenuate UVA and an effective proportion of a second metal oxide powder having a secondary particle size selected for the second metal oxide powder to attenuate UVB. The mean secondary particle size of the first metal oxide powder is greater than the mean secondary particle size of the second metal oxide powder. In one embodiment, the first and the second metal oxide powders are both zinc oxide. | 06-11-2009 |
20090257966 | TERNARY AND QUATERNARY WAX-RESIN COMPOSITES FOR USE IN COSMETIC AND PHARMACEUTICAL PREPARATIONS - A wax-resin composite is made by melting thermoplastic hydrocarbon resin, optionally with an antioxidant. The melted thermoplastic hydrocarbon resin and waxes are blended at a temperature sufficient to melt the waxes. After blending and melting, the blended thermoplastic hydrocarbon resin and waxes are allowed to solidify. Solidification is followed by post-processing the wax-resin composite mixture to form slabs, pastilles, flakes or other forms. A method for producing a wax-resin composite comprises at least partially solvating a thermoplastic resin in a solvent to form a resin-solvent blend. This may be done at a heat of 80-85° C. A composition of molten wax is blended with the resin-solvent blend. The resin-solvent blend and a molten wax are blended to form a wax-resin blend. This is followed by removing the solvent from said wax-resin blend. | 10-15-2009 |

20100003290 | OIL AND WATER REPELLENT COSMETIC POWDER AND METHODS OF MAKING AND USING SAME - Disclosed is a coated powder that comprises a powder substrate having a coating thereon that includes a 2-(perfluoroalkyl)ethyl alcohol phosphate of the formula | 01-07-2010 |
20100061947 | UV PROTECTIVE COSMETIC PRODUCT INCORPORATING TITANIUM DIOXIDE AND TRANSPARENT IRON OXIDE - A cosmetic composition comprises a transparent substantially colorless pigment. The substantially colorless pigment comprises a first group of particles sufficiently small to be substantially transparent to visible light and substantially opaque to ultraviolet B light. The substantially colorless pigment further comprises a second group of particles sufficiently small to be minimally reflective to visible light and substantially opaque to ultraviolet A light. A second group of particles results in minimal visible reflection by the cosmetic composition. A substantially transparent coloring pigment substantially transmits visible light and reflects a substantial portion of incident ultraviolet A light to impart color to tint visible light reflected by the cosmetic composition when they cosmetic composition is disposed over the skin. These materials are maintained in a carrier vehicle. | 03-11-2010 |
