Abstract (en)

[origin: WO2004108863A1] The invention relates to the use of alkoxylated cross-linked polyglycerols having multifunctional electrophilic compounds. Said polyglycerols have a molecular weight of between 1000 - 100.000 units and have between 5 - 100 glycerol units which are alkoxylated by C2-C4-alkylen oxide groups or a mixture of said type of alkylen oxide groups such that the cross-linked, alkoxylated polyglycerol has an alkoxylation degree of between 1 - 100 alkylen oxide units per free OH group. The invention also relates to the use of said polyglycerols for the demulsification of oil/water emulsions in amounts ranging from 0.0001 5 wt.- %, in relation to the oil content of the emulsion which is to be demulsified.
