Abstract
Abstract New stable stain removing compositions are provided which contain 15 to 35 percent by weight of an anionic surfactant, optionally 3 to 25 percent by weight of a water-insoluble alcohol containing 8 to 18 carbon atoms, 3 to 25 percent by weight of pine oil, of a reaction product of a fatty acid containing 8 to 18 carbon atoms and sorbitol, and/or of at least one alkylene oxide adduct of the formula RO(CH 2 CHR 1 O) n H or of an ester of the formula Z'COOR 2 , wherein R is an aliphatic hydrocarbon radical of 12 to 18 carbon atoms, R' is an aliphatic hydrocarbon radical of 7 to 17 carbon atoms, R 1 is hydrogen or methyl, R 2 is ##STR1## or --CH 2 CHOHCH 2 OH, and n is an interger from 1 to 12, the amount of components (2) and (3) together being at least 12 percent by weight, and 30 to 73 percent by weight of water. These agents provide excellent cleaning and dispersing power and are particularly adapted to use in cleaning or combined cleaning (washing) and dyeing processes.
