    摘要: The present invention relates to a method of producing a granular formulation of colorants soluble in plastics, which method comprises suspending in water a filter cake obtained from preparation of the colorant, adding thereto from 0.1 to 5.0% by weight, calculated with respect to the weight of colorant, of a polyvinylpyrrolidone and, where appropriate, further adjuvants, and then drying the aqueous suspension to form granules, to the granular formulations obtainable according to that method, and to the use thereof in the production of colored plastics or colored polymeric particles.

    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.
