Quaternary salts of fatty acid ester with triethanolamine and their use as fabric softeners.

摘要

The invention relates to biodegradable softening compounds of formula (I): [(R) {sub, 4-m} -N (sup +}) - [CH {sub, 2}) {sub, n} -Y {sup, 1}] {sub, m}] X {sup, -} with a lower acid value or equal to 6.5. a process is also provided for making the compounds. The softener may be incorporated in softening compositions to form solid and liquid compositions, including liquid dispersion and clear compositions.
