COMPOSITE FOR PROTECTION AGAINST UV-RADIATION (VARIANTS), METHOD FOR PROTECTION AGAINST UVRADIATION (VARIANTS) |
摘要 |
FIELD: organic chemistry. SUBSTANCE: invention relates to sun-protective composites comprising derivative of dibenzoylmethane (UV-A-filter) such as 4-(1,1-dimethylethyl)-4'-methoxybenzoylmethane and stabilizing agent for derivative of dibenzoylmethane of the formula (I) or (II) or their mixture where R1 are similar or different and each means alkyl group with 1-22 carbon atoms or diol of the formula HO-R2-OH, or polyglycol of the formula HO--OH and where R2 and R3 are similar or different and each means alkylene group with direct of branched chain with 1-6 carbon atoms; each of m and n = 1-100 or their mixture. These diesters or polyesters of the formula (I) or (II) are rather effective agents for stabilization of UV-A-filter based on derivative of dibenzoylmethane providing the enhanced effectiveness for prolonged time. Invention proposes also method for protection against UV-radiation using the proposed composition. EFFECT: improved method for protection, valuable properties of composite. 20 cl, 9 dwg, 3 tbl |
