Abstract: Disclosed is a hair care composition comprising a (i) an anionic surfactant; (ii) an amphoteric or zwitterionic surfactant; (iii) piroctone olamine; iv) a polyaspartate or its derivative presented by the structure of formula (1), where the sum of m+n is from 2 to 10000, R1, R2 are independently selected from the group consisting of H, OH, (O)mG, m is 0 or 1, G is independently selected from the group consisting of H and a substituted or unsubstituted C1-C12 organic group, ammonium salt, wherein non-limiting examples of the metal salts include Na, K, Ca, Mg, Al salts; and v) a cosmetically acceptable carrier; wherein the weight ratio of said polyaspartate or its derivative to said piroctone olamine in the composition is at least 2:3. It has been shown to improve the stability of the piroctone olamine.

Abstract: Disclosed is a hair care composition comprising a (i) a benzophenone or benzophenone derivative which is one or more components selected from benzophenone, benzophenone-1, benzophenone-2, benzophenone-3, benzophenone-6, benzophenone-7, benzophenone-8, benzophenone-10 and benzophenone-12 thereof; (ii) a piroctone olamine; (iii) a silicone compound; a cosmetically acceptable carrier; wherein amount of said benzophenone or benzophenone derivatives is 0.2 to 10% by weight of the total composition. It has been shown to improve the deposition and stability of the piroctone olamine.

Abstract: This invention relates to a hair care composition more particularly to a wash-off composition, especially preferred being a shampoo or a conditioner, which provides the desired anti-dandruff efficacy with enhanced stability of the active materials on hair/scalp during use. This is achieved through a judicious combination of an organic UV filter, a zinc compound and selective anti-dandruff agent. The composition comprises 0.01 to 3% by weight zinc pyrithione, an organic UV filter and 0.1 to 5% by weight additional zinc compound. The weight ratio of zinc compound to zinc pyrithione is over 3:1.

Abstract: Disclosed is an in-vitro method to determine efficacy of a cosmetic composition or of one or more ingredients comprised therein to inhibit a particulate pollutant from contacting skin, said method comprising the steps of: (i) contacting a human skin equivalent with a cosmetic composition to form, upon drying, a layer thereof extending along mutually perpendicular X and Y and Z axis where along said Z axis said layer is 1 to 100 ?m, where said Z axis indicates thickness of said layer; (ii) depositing, on said layer, a known amount of a model fine particulate matter comprising a first substance responsive to depth profile analysis where said cosmetic composition comprises a second substance, not comprised in said model fine particulate matter but also responsive to said depth profile analysis where the response of said first and second substances are distinguishable; (iii) for a pre-determined period after depositing said model fine particulate matter, periodically measuring response of said first and said seco
