Alkyl3-oxoalkanoates

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.

Benzimidazole/benzofuryl-benzazole silicon compounds and UV-photoprotective compositions comprised thereof

This invention includes an alkyl 3-oxoalkanoate, and processes for its preparation and use for the synthesis of fatty hydroxylated amino acids, fatty amino alcohols and ceramides.

Alkyl 3-oxoalkanoate and process for the preparation thereof

The present invention relates to compounds corresponding to the formula: ##STR1## the compounds being in the form of mixtures of isomers at least on the amino alcohol part of the said formula (I). The invention also relates to a process for their preparation and their use, in particular for the treatment and care of the skin, the hair, the nails and the eyelashes in cosmetics or in dermatology.

Ceramide compounds, process for their preparation and use

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.
