Abstract
Abstract The invention relates to new polyethylene glycol derivatives. These compounds correspond to the general formula: <IMAGE> (I) <IMAGE> in which R denotes an alkyl and/or alkoxymethyl and/or alkenyloxymethyl radical or a mixture of these radicals, &upbar& n denotes an average number of units from 20 to 500 and preferably from 30 to 200, and &upbar& x and &upbar& y denote average numbers of units from 0 to 8, it being possible for ( &upbar& x+ &upbar& y) to vary from 1 to 8. They can be used in cosmetic or pharmaceutical compositions, in particular as thickeners.
