Abstract

Disclosed is a cleaning agent and method for the cleaning of apparatus used for the fabrication of reactive, multiple-component mixtures containing isocyanate. The cleaning agent consists of 50 to 75 weight-percent of a plasticizer from the group of short to medium chain length phthalic acid esters or alkylsulfonic acid esters of phenols, and 50 to 25 weight-percent of a mineral oil fraction of an aliphatic, naphthenic and/or aromatic hydrocarbon, or mixtures thereof, in the range of from 8 to 17 carbon atoms.
