Abstract

A composition useful as a parting agent for concrete formwork is provided. The composition comprises water; a completely or predominantly unsaturated fatty alcohol containing 6 to 22 carbon atoms and with an iodine value of 40 to 200; and an alkyl or alkenyl oligoglycoside having an alkyl or alkenyl group containing 4 to 22 carbon atoms, a sugar unit containing 5 or 6 carbon atoms and a degree of oligomerization of 1 to 10. The parting agent is particularly storage-stable at low temperatures.
