Abstract

Abstract A detergent composition for dry cleaning comprising from 10 to 30 percent by weight of an alkanolamine salt of a linear alkylbenzenesulfonic acid having 10 to 14 carbon atoms in the alkyl group, from 30 to 50 percent by weight of a dialkyl ester of sulfosuccinic acid having 8 to 9 carbon atoms in the alkyl group, from 2 to 20 percent by weight of an adduct of 1 to 7 moles of an alkylene oxide to a higher fatty acid alkanolamide, and the balance is essentially an organic solvent effective for dry cleaning.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 150 words
A dry cleaning detergent composition consisting essentially of (A) from 10 to 30 percent by weight of an alkanolamine salt of a linear alkylbenzenesulfonic acid having 10 to 14 carbon atoms in the alkyl group and wherein said alkanolamine is a monoalkanolamine, dialkanolamine or trialkanolamine having 2 or 3 carbon atoms in the alkanol group, (B) from 30 to 50 percent by weight of a dialkyl ester of sulfosuccinic acid having 8 or 9 carbon atoms in the alkyl group, (C) from 2 to 20 percent by weight of an adduct of 1 to 7 moles of an alkylene oxide having 2 or 3 carbon atoms to a higher fatty acid alkanolamide prepared from a fatty acid having from 10 to 18 carbon atoms and a monoalkanolamine or dialkanolamine having 2 or 3 carbon atoms in the alkanol group, and (D) the balance is essentially an organic dry cleaning solvent.
Claim 2
Dependent Claim 150 words
A dry cleaning detergent composition consisting essentially of (A) from 10 to 30 percent by weight of an alkanolamine salt of a linear alkylbenzenesulfonic acid having 10 to 14 carbon atoms in the alkyl group and wherein said alkanolamine is a monoalkanolamine, dialkanolamine or trialkanolamine having 2 or 3 carbon atoms in the alkanol group, (B) from 30 to 50 percent by weight of a dialkyl ester of sulfosuccinic acid having 8 or 9 carbon atoms in the alkyl group, (C) from 2 to 20 percent by weight of an adduct of 1 to 7 moles of an alkylene oxide having 2 or 3 carbon atoms to a higher fatty acid alkanolamide prepared from a fatty acid having from 10 to 18 carbon atoms and a monoalkanolamine or dialkanolamine having 2 or 3 carbon atoms in the alkanol group, and (D) the balance is essentially an organic dry cleaning solvent.
Claim 3
Dependent Claim 28 words
A dry cleaning detergent composition according to claim 1 wherein the amount of free sulfuric acid in the linear alkylbenzenesulfonic acid is less than 0.5 percent by weight.
Claim 4
Dependent Claim 23 words
