Abstract
Abstract Emulsifier-solvent scour compositions which are stable at elevated temperatures when incorporated into aqueous caustic media for treatment of textile materials. The scour compositions comprise an inert organic solvent media containing: A. 5 to 35% of at least one phosphate ester of an ethoxylated and/or propoxylated C 8 -C 24 aliphatic or aromatic alcohol; B. 1 to 10% of at least one C 8 -C 24 carboxylic acid of salt thereof; and C. 4 to 20% of either I. at least one member from the group of sulfonated fatty acids or salts thereof, ethoxylated and/or propoxylated C 8 -C 24 carboxylic acid or glyceride, sulfonated alkyl diphenyl oxide or salts thereof, or substituted imidazoline; or Ii. at least one of an ethoxylated and/or propoxylated C 8 -C 24 aliphatic or aromatic alcohol, amine or mercaptan; a sulfonated alkyl benzene, condensation products or salts thereof; or a fatty diethanol amide obtained from reacting diethanolamine with a C 8 -C 24 fatty acid or ester.
