摘要:
A method of preparing a composition, comprising (a) a micronised insoluble organic UV absorber, which method comprises grinding the insoluble organic UV absorber, in coarse particle form, in a grinding apparatus, in the presence of a grinding aid selected from the groups (b 1 ) carboxylic acids and their salts; (b 2 ) fatty acid esters (b 3 ) alkyl phosphates or phosphoric acid esters; (b 4 ) ethoxylated carboxylic acids or polyethyleneglycol (PEG) esters; (b 5 ) fatty alcohol polyethyleneglycol (PEG) ethers of fatty alcohols; (b 6 ) polyethylene/polypropylene -glycol ethers of saturated or unsaturated C 4 - C 28 fatty acids; (b 7 ) ethoxylated alkylphenols or ethoxylated alkylphenyl ethers; (b 8 ) esters of polyol and mono-, di- or tri-glycerides; (b 9 ) esters of fatty acids and saccharose; (b 10 ) sorbitan mono- and di-esters of saturated and/or unsaturated C 6 - C 22 fatty acids and ethylene oxide groups; and (b 11 ) surfactants which are mainly acting as detergent or cleansing agents.
