Abstract
Official abstract text for this publication.
The present invention includes an ultraviolet radiation absorbing polymer composition comprising the polymer compound of formula and compositions containing such an ultraviolet radiation absorbing polymer composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light-protective preparation comprising: (i) an ultraviolet radiation absorbing polymer composition comprising a polymer compound of the formula wherein the sum of n and m is a number from 3 to 10; and (ii) a dicarboxylic acid ester. 2. The preparation of claim 1 , wherein the polymer compound has a weight average molecular weight (M) of about 500 to about 50,000 Da. 3. The preparation of claim 1 comprising from 0.1 to 30% by weight, based on the total weight of the composition, of the ultraviolet radiation absorbing polymer composition. 4. The preparation of claim 1 comprising from 1 to 60% by weight, based on the total weight of the composition, of the dicarboxylic acid ester. 5. The preparation of claim 1 further comprising propylene glycol. 6. The preparation of claim 1 further comprising silica. 7. The preparation of claim 1 in the form of an oil-in-water emulsion.
