The present invention relates to a composition according to the present invention comprises: (a) at least one particle comprising at least one cationic polymer, at least one anionic polymer, and at least one hydrophilic or water-soluble UV filter; and (b) at least one physiologically acceptable volatile medium. The composition according to the present invention is stable, and can have a variety of cosmetic functions. For example, the composition according to the present invention can prepare a film which can have cosmetic effects such as UV filtering, as well as absorbing or adsorbing malodor, changing the appearance of a keratin substrate such as skin, changing the feel to the touch of the keratin substrate, and/or protecting the keratin substrate from, for example, dirt or pollutants.

Combination of polyion complex particle and hydrophilic or water-soluble UV filter

The present invention relates to a composition in the form of an emulsion, comprising: (a) at least one oil-absorbable organic particle which has an oil-absorbing capacity of 170 ml/100 g or more, preferably 250 ml/100 g or more, and more preferably 400 ml/100 g or more, and a volume-average particle size of less than 30 &#x3bc;m, preferably less than 25 &#x3bc;m, and more preferably less than 20 &#x3bc;m, (b) at least one oil; (c) at least one emulsifier; (d) water; and (e) optionally at least one additional oil-absorbable particle, wherein the oil-absorbing capacity of the total of the (a) oil-absorbable organic particle and the (e) additional oil-absorbable particle in the composition is more than 170 ml/100. The composition according to the present invention can provide long-lasting matte effects, while imparting excellent texture.

Emulsion with matte effects and excellent texture

The present invention relates to a composition according to the present invention comprises: (a) at least one particle comprising at least one cationic polymer, at least one anionic polymer, and at least one non-polymeric acid having two or more pKa values or salt(s) thereof; and (b) at least one physiologically acceptable volatile medium. The composition according to the present invention is stable, and can have a variety of cosmetic functions. For example, the composition according to the present invention can prepare a film which can have cosmetic effects such as absorbing or adsorbing malodor, changing the appearance of a keratin substrate such as skin, changing the feel to the touch of the keratin substrate, and/or protecting the keratin substrate from, for example, dirt or pollutants.

Combination of polyion complex particle and non-polymeric acid having two or more acid dissociation constants
