摘要： 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.

摘要： 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 μm, 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 second substance by said depth profile analysis, to thereby determine the amount of said model fine particulate matter at defined intervals along said Z axis; and, (iv) ascertaining said efficacy based on the amount of said model fine particulate matter at said defined intervals along said Z axis throughout said pre-determined period.

摘要： 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. Disclosed is a hair care composition comprising: (i) 0.01 to 3% by weight zinc pyrithione; (ii) 1 to 5% by weight amino acid; and (iii) 0.1 to 5% by weight additional zinc compound.

摘要： 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.

摘要： 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.
