摘要:
Novel liposoluble and photostable N-substituted benzimidazole/benzofuryl-benzazole silicon-containing compounds are conspicuously excellent UV-absorbers and are conveniently formulated, e.g., into topically applicable sunscreen/cosmetic compositions well suited for the UV-photoprotection of human skin and/or hair.
摘要:
Stable, topically applicable cosmetic/dermatological sunscreen compositions, well suited for the UV-photoprotection of human skin/keratinous materials, contain a thus effective amount of at least one novel amine, amide, sulphonamide or carbamate substituted benzalmalonic salt compound.
摘要:
The subject of the invention is a process for the preparation of 2-aminoalkane-1,3,4-triols, in a single stage, preferably a single reduction state, from alkyl 2-hydroxyimino-3-oxo-4-acyloxyalkanoates. The invention makes possible a significant reduction in the number of stages and a marked improvement in the synthesis yields.
