ABSTRACT:
Surfactant-modified, 1,1,2-trichloro-1,2,2-trifluoroethane solvent compositions are provided which contain small but effective amounts, i.e., about 0.2 to about 0.5 weight percent of solvent soluble/water insoluble surfactant and/or surfactant demulsifiers and adjust to accommodate. Of particular significance are the compositions containing N-acylated sarcosine surfactants and demulsifiers of the group acetylenic diols, aliphatic primary alcohols of 6 to 12 carbon atoms, and alkyl phosphate triesters of 3 to 12 carbon atoms. The demulsifier containing compositions have the properties of effectively and essentially completely displacing water or aqueous solutions from many substrates and, even under conditions of severe agitation, separating them for removal by decantation from the solvent layer without the drawback of forming stable emulsions that prevent said decantation and interfere with sufficient processing of the solvent drying compositions through the drying apparatus.
