  • Self adapting polymers for anhydrous sunscreen formulations
    Patent number: 10729625
    Abstract: Compositions comprising sun-care actives and self adapting polymers are disclosed. Self adapting polymers align themselves with the hydrophilic group pointing to the surface during application thus delivering an aesthetically pleasing surface to the consumers with a pleasant after feel. These polymers then rearrange upon contact with water so that the hydrophobic groups now point to the surface which then increases the water resistance of the formulation.

  • OIL-IN -WATER EMULSION SUNSCREEN COMPOSITION
    Publication number: 20170165187
    Abstract: In accordance with the present invention there is provided an oil-in-water emulsion sunscreen composition comprising (a) a UV active, (b) a first emulsifier having an HLB value less than 5 and (c) optionally a second emulsifier having an HLB value greater than 5 present in an amount of less than 0.2% w/w of the composition. The oil-in-water sunscreen composition is characterized by the absence of an emulsifiable polymer and is capable of providing little to no whitening when applied to wet skin.

  • Antiperspirant Compositions
    Publication number: 20120294818
    Abstract: Compositions containing a relatively high concentration of electrolytes and a thickening agent, wherein the thickening agent comprises a strongly swellable, lightly to moderately crosslinked polyvinyl pyrrolidone. The polyvinyl pyrrolidone thickening agent is characterized by an aqueous gel volume of about 15 to 150 ml/g and a Brookfield viscosity of at least 10,000 cps for a 5% aqueous solution at 25° C.
