    Abstract: PROBLEM TO BE SOLVED: To provide a new type cosmetic or dermatological composition for protecting the skin, having improved stability and good formulation characteristics and also exhibiting good functional characteristics and high sunburn preventive factor. SOLUTION: This composition as the subject sunscreen preparation comprises (A) a copolymer and (B) an inorganic UV filter; wherein the copolymer A is such as to be obtained by (i) free radical solution polymerization of a monomer mixture comprising (a) 0.01-99.99 wt.% of a monomer selected from the group consisting of N-vinylimidazoles and diallylamines, (b) 0.01-99.99 wt.% of a neutral or basic water-soluble monomer, (c) 0-50 wt.% of an unsaturated acid (anhydride), (d) 0-50 wt.% of a free radical-copolymerizable monomer differing from the components (a), (b) and (c), and (e) 0-10 wt.% of a monomer acting as a crosslinking agent and having at least ethylenically unsaturated nonconjugated double bonds, and (ii) partially or wholly quaternizing or protonating the resultant polymer.

    Abstract: New oligomeric 4,4-diarylbutadiene carboxylic acid ester or amide sunscreen compounds. Oligomeric 4,4-diarylbutadiene carboxylic acid esters or amides of formula (I) are new. R1, R2 = H; aliphatic-, cycloaliphatic-, aromatic- or araliphatic- group; or carboxylate, sulfonate or ammonium; R3 = aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic group; carbonyl, sulfonyl, phosphonyl, carboxylic acid ester or CN; Y = O or N(R4); R4 = H or aliphatic-, cycloaliphatic-, aromatic-,araliphatic or heterocyclic group; m = 2-10; n = 1-3 X = the residue of a polyol with 2-10 OH groups (corresponding to m). Am Independent claim is included for preparation of (I).

    Abstract: Described are cosmetic preparations containing light-screening agents designed to protect the human epidermis against UV light in the region from 280 to 400 nm. The light-screening agents are contained in a carrier compound suitable for cosmetic purposes together with compounds of the formula (I): (see formula I) where R1 and R2 are identical or different straight-chain or branched aliphatic or cycloaliphatic radicals which are in the para and/or ortho position and have 1 to 18 carbon atoms, R1 may additionally be a hydrogen atom, and n is 1 or 2, and with compounds which absorb in the UV-B region. The above mentioned compounds of the formula I are in amounts which make them active as photostable UV-A filters.
