Abstract
The present invention relates to softening compounds; stable, homogeneous, preferably concentrated, aqueous liquid and solid textile treatment compositions; and intermediate compositions and/or processes for making said compositions. The compositions of the present invention contain diester quaternary ammonium compounds wherein the fatty acyl groups have an Iodine Value of from greater than about 5 to less than about 100, a cis/trans isomer weight ratio of greater than about 30/70 when the Iodine Value is less than about 25, the level of unsaturation being less than about 65% by weight, wherein said compounds are capable of forming concentrated aqueous compositions with concentrations greater than about 13% by weight at an Iodine Value of greater than about 10 without viscosity modifiers other than normal polar organic solvents present in the raw material of the compound or added electrolyte.
