long chain di (acyloxy) dialkylsilane, di (acyloxy) diarylsilane, di (acyloxy) dialkoxysilane and tetra (acyloxy) silanes, process for their manufacture and their use for the production of vesicles, they produced vesicles (siosomen) and their use as carriers of active substances.

摘要

The invention relates to novel long chain di(acyloxy)dialkylsilanes, di(acyloxy)diarylsilanes, di(acyloxy)dialkoxysilanes and tetra(acyloxy)silanes of the general formula I IMAGE in which the radicals R1 and R2 represent long chain radicals and the radicals R3 and R4 represent comparatively short chain radicals according to the definition in the description. These compounds are suitable for the preparation of vesicles which are related to the liposomes and are designated as siosomes. These vesicles (siosomes) are suitable as carriers of various active substances. IMAGE
