Synthesis and characterisation of terminal carbohydrate modified poly(dimethylsiloxane)s

Abstract

In the 1990's, carbohydrate modified silicones were developed as a novel c]ass of hydrophilic modified silicones which are now ready for marketing and industrially available, mainly as ingredients of cosmetic formulations. This report focuses on the synthesis of α,ω-carbohydrate modified linear poly(dimethylsiloxane)s by hydrosilylation thesised and reacted with a hydrodimethylsilyl-terminated poly(dimethylsiloxane) applying Speier's catalyst. The resulting oils were characterised by MALDI TOF MS and NMR spectroscopy. Deprotection gave a series of novel amphiphilic modified silicones, which were more viscous than their protected analogues, due to hydrogen bonding.
