Non-phosphate detergent-softening compositions
First Claim
1. A clear, stable liquid detergent composition free of phosphate and possessing detergent anti-static and softening properties consisting essentially of (a) about 10-40% by weight of a synthetic organic detergent selected from the group consisting of (1) a C16 -C22 alkyl-di C1 -C3 alkyl amine oxide and (2) water soluble non-ionic surface-active compounds derived from the condensation of a C8-C50 hydrophobic compound with from 5 to 200 moles of ethylene oxide and (3) mixtures of (1) and (2);
- and about (b) 3-15% by weight of a mixture of (1) a quaternary ammonium fabric softener selected from the group consisting of di-long chain and di- short chain quaternary ammonium compounds and mono or di- long chain alkyl imidazolinium compounds of the formulae;
##EQU4## wherein R1 and R2 are C8 -C22 alkyl radicals;
R3 and R4 are C1 -C4 alkyl;
R5 is C1 -C4 alkyl or hydroxyalkyl, or C8 -C22 alkyl radical, and X is a water-soluble salt forming anion; and
(2);
a polyethoxylated quaternary ammonium compound containing from 10 to 60 moles of ethylene oxide of the formula;
##EQU5## wherein R1 is C8 to C22 radical, R6 is C8 to C22 radical, or -(CH2 CH2 O)n H, X is an anion as above defined and n is a number from 10 to 60 in an aqueous solvent medium, the ratio of (a) to (b) ranging from 1;
1 to 5;
1 and the ratio of (b)1 to (b)2 ranging from 6;
1 to 1;

Abstract
A non-phosphate liquid softergent composition possessing antistatic properties comprising 10-40% of a non-ionic surfactant and/or amine oxide surfactant, and about 3-15% of a mixture of a quaternary ammonium softener and a poly-ethoxylated alkyl or dialkyl methyl ammonium halide in an aqueous solvent medium. The detergent compositions are single phase, clear, stable liquids but may be made opaque, creamy or opalescent, if desired. Also described is a method for simultaneously washing and softening laundry without imparting water repellancy to fabrics treated therewith.
