Abstract: A meta-stable composition, a product including the meta-stable composition, and a method of protecting a keratinous substrate from UV radiation by applying the product are provided. The meta-stable cosmetic composition includes at least one water-in-oil emulsifier having a hydrophilic-lipophilic balance (HLB) of less than 6, at least one non-ionic oil-in-water emulsifier having an HLB of greater than 9, at least one ionic surfactant, and at least one skin care active ingredient. The weight ratio of the at least one non-ionic oil-in-water emulsifier to the at least one water-in-oil emulsifier is about 0.02 to about 2.0. The meta-stable cosmetic composition converts from an oil-in-water (O/W) emulsion to a water-in-oil (W/O) emulsion upon rubbing.

Abstract: The present invention relates to a sunscreen composition comprising: a. an aqueous phase; b. an oil phase comprising at least one cosmetically acceptable oil; c. at least one sunscreen active; and d. up to about 5% by weight, based on the total weight of the composition, of an emulsifier system comprising; i. at least one ionic surfactant; ii. at least one nonionic surfactant having an HLB of greater than or equal to about 14; and iii. at least one nonionic surfactant having an HLB of less than or equal to about 10; wherein the composition is an oil-in-water emulsion containing oil droplets having an average particle size of from about 100 to 150 nm, is alcohol-free, and appears semi-transparent to transparent upon application onto an end-user's skin.

Abstract: The present invention is directed to an automated vessel puncture device, methods of mapping three-dimensional views of subcutaneous vessels and methods for providing simultaneous real-time diagnostic assay.

Abstract: A sunscreen composition containing: (a) a polyacrylate booster comprising at least one acrylates copolymer having a weight average molecular weight ranging from about 75,000 to 140,000 g/mol and a Tg ranging from ?20 to 50 C; and (b) a UV filter system containing a combination of UV filters comprised of: octocrylene, avobenzone, octisalate, and homosalate, and optionally oxybenzone; wherein the ratio of each filter relative to avobenzone is as follows: the ratio of octocrylene to avobenzone is 1.6:1.0 to 2.4:1.0, the ratio of oxybenzone to avobenzone 0.0:1.0 to 0.016:1.0, the ratio of octisalate to avobenzone is 1.3:1.0 to 2.0:1.0, and the ratio of homosalate to avobenzone is 2.3:1.0 to 3.
