    摘要: The present invention provides a micronised, insoluble organic UV absorber which is especially suitable for use in pharmaceutical or cosmetic applications, with the exclusion of o-hydroxyphenyl-s-triazines having formula (I) in which R.sub.a, R.sub.b and R.sub.c, independently, are hydrogen, halogen, C.sub.1 -C.sub.18 alkyl or C.sub.1 -C.sub.18 alkoxy, and R.sub.d and R.sub.e, independently, are hydrogen or C.sub.1 -C.sub.18 alkoxy, with the provisos that one of R.sub.d and R.sub.e is always C.sub.1 -C.sub.18 alkoxy, and that, if R.sub.b, R.sub.c, R.sub.d and R.sub.e are each C.sub.1 -C.sub.18 alkoxy, then R.sub.a is halogen, C.sub.1 -C.sub.18 alkyl or C.sub.1 -C.sub.18 alkoxy; and a sunscreen composition comprising the micronised, insoluble organic UV absorber together with a cosmetically compatible carrier. The UV absorber is of the oxalamide, triazine, vinyl-group containing amide or cinnamic acid amide classes.

    摘要: Described are diester amine adducts of formula (1) wherein R1, R2, R3, R4 are each independently of one another C4-C22alkyl; C2-C22alkenyl; or C5-C7cycloalkyl; X1 and X2 are each independently of the other hydrogen, C1-C4alkyl; C2-C4hydroxyalkyl or C2-C4hydroxyhaloalkyl; Y is a radical of formula (1b); A1 is C2-C3alkylene or 2-hydroxy-n-propylene; X3 is hydrogen; C1-C4alkyl, C2-C4hydroxyalkyl; or C2-C4hydroxyhaloalkyl; (A) is an asymmetrical carbon atom in the R- or S-configuration, wherein, if C1=R, C2=R; C1=S, C2=S; and C1=R; C2=S; m1 is 1 or 2; and n is an integer from 1 to 4; p is 0 or 1; which adducts may be in the form of free bases or ammonium salts. Said compounds are precursors of compounds having good complex-forming properties and are thus able to effectively bind heavy metal ions such as iron, zinc, magnesium or copper ions and to prevent metal-initiated oxidations after enzymatic or chemical cleavage. They have a plurality of uses, for example in foods, beverages, derusting and decalcification baths, as additives in liquids for cooling-water circuits, in personal-care products, as bleaching stabilizers, in cleaning agents and detergents, in the textile industry and also as soft handle agents for organic fibre materials.
