Abstract (en)
[origin: WO0058427A1] The invention relates to new formulations comprising esterquats and amides, and their use in detergent, fabric softening, dryer sheets, personal care applications and cleaners having improved hydrolytic stability and concentratibility. The invention also relates to an improved process for making these formulations where unreacted fatty acid used in the esterification step is reacted with an amine to form the amide in situ. This improved process offers the advantages of reducing total reaction time, providing an amide that stabilizes the formulation and eliminating free fatty acid that can hurt the stability of the formulation.
