<p>Disclosed is a UV filter composition comprising (a) an organic UV absorber of formula (1), wherein R<SUB>1</SUB> and R<SUB>2</SUB>, independently of one another, are C<SUB>3</SUB>-C<SUB>18</SUB>alkyl; C<SUB>2</SUB>-C<SUB>18</SUB>alkenyl; a radical of the formula -CH<SUB>2</SUB>-CH(OH)-CH<SUB>2</SUB>-O-T<SUB>1</SUB>; or R<SUB>1</SUB> and R<SUB>2</SUB> are a radical of the formula (4a); R<SUB>7</SUB> is a direct bond; a straight-chain or branched C<SUB>1</SUB>-C<SUB>4</SUB>alkylene radical or a radical of the formula (I) or (II); R<SUB>8</SUB>, R<SUB>9</SUB> and R<SUB>10</SUB>, independently of one another, are C<SUB>1</SUB>-C<SUB>18</SUB>alkyl; C<SUB>1</SUB>-C<SUB>18</SUB>alkoxy or a radical of the formula (III); R<SUB>11</SUB> is C<SUB>1</SUB>-C<SUB>5</SUB> alkyl; m<SUB>1</SUB> is a number from 1 to 4; p<SUB>1</SUB> is 0; or a number from 1 to 5; A<SUB>1</SUB> is a radical of the formula (1b), (1c) or (1d); R<SUB>3</SUB> is hydrogen; C<SUB>1</SUB>-C<SUB>10</SUB>alkyl; -(C H<SUB>2</SUB> C H R<SUB>5</SUB>-O) n<SUB>1</SUB>-T<SUB>2</SUB>; or -CH<SUB>2</SUB>-CH(-OH)-CH<SUB>2</SUB>-O-T<SUB>2</SUB>; R<SUB>4</SUB> is hydrogen; M; C<SUB>1</SUB>-C<SUB>5</SUB>alkyl; or -(C H<SUB>2</SUB>)m<SUB>2</SUB> -O-T<SUB>3</SUB>; R<SUB>5</SUB> is hydrogen; or methyl; T<SUB>1</SUB>, T<SUB>2</SUB> and T<SUB>3</SUB> independently from each other are hydrogen; or C<SUB>1</SUB>-C<SUB>18</SUB>alkyl; Q<SUB>1</SUB> is C<SUB>1</SUB>-C<SUB>18</SUB>alkyl, M is a metal cation; m<SUB>2</SUB> is 1 to 4; and n<SUB>1</SUB> is 1-16, (b) dimethyl capramide, (c) a cosmetically acceptable carrier; and water.</p> |
