摘要： Disclosed is a method of determination of a pollution protection factor (PPF) of a cosmetic composition, comprising: (a) a step of testing, by any known test method, the ability (α) of the cosmetic composition to render ineffective at least one type of pollutant present on the skin and expressing it on a scale of 0 to 1, followed by calculating said PPF by equation A, where (1−α) indicates corresponding potential residual damage to the skin wherein said composition comprises at least one ingredient known to render ineffective said at least one type of pollutant and said at least one ingredient is an anti-inflammatory or antioxidant; or alternatively, (b) a step of testing, by any known test method, the ability (β) of the cosmetic composition to inhibit the contact of at least one type of pollutant with skin and expressing it also on a scale of 0 to 1, followed by calculating said PPF by equation B, where (1−β) indicates corresponding potential residual damage to the skin wherein said composition comprises at least one ingredient known to inhibit the contact of at least one type of pollutant with skin and wherein said ingredient is a sunscreen, a barrier enhancer or a polymer; or further alternatively, (c) a step of testing, by any known test method, the ability (γ) of the cosmetic composition to remove at least one type of pollutant present on the skin, expressing it also on a scale of 0 to 1, followed by calculating said PPF by equation C, where (1−γ) indicates corresponding potential residual damage to the skin.

摘要： The invention relates to a personal care composition, more particularly to a composition for use to reduce or prevent inflammation on a topical surface of a human or animal body. The composition could be delivered in the form of a skin, scalp, hair or oral care product, more particularly a skin care product. The benefit is delivered via a combination of a polyunsaturated fatty acid (PUFA) or an ester thereof and a vitamin B3 compound wherein the mole ratio of the PUFA or ester thereof to the vitamin B3 compound is 1:15 to 1:500.
