Abstract:
Fabric softening compounds having the formula:[RC(O)OC2H4]nN+(R1)mXâˆ’wherein each R in a compound is a C6-C22 hydrocarbyl group having a cis:trans isomer ratio above 3:1 and below about 20:1 based upon the equivalent fatty acid, n is a number from 1 to three on the weight average in any mixture of compounds, each R1 in a compound is a C1-3 alkyl or hydroxy alkyl group, the total of n and the number of R1 groups that are hydroxyethyl groups equaling 3, n+m equaling 4, and X is a softener compatible anion, the compound having (a) a Hunter L transmission of at least about 85; (b) only very low, non-detectable levels, at the conditions of use, of odorous compounds selected from the group consisting of: isopropyl acetate; 2,2â€²-ethylidenebis(oxy)bispropane; 1,3,5-trioxane; and/or short chain fatty acid esters having 4-12 carbon atoms; or (c) both.
