FABRIC SOFTENER ACTIVE COMPOSITION AND METHOD FOR MAKING IT
摘要
Reacting at least one tris-(2-hydroxyethyl)-amine fatty acid ester with dimethylsulfate at a molar ratio of dimethylsulfate to amine nitrogen of from 0.79 to 0.94 until the reaction mixture has a total amine number of from 7 to 20 mg KOH/g provides novel fabric softener active compositions with a low content of methanol, comprising from 65 to 98% by weight of tris-(2-hydroxyethyl)-methylammonium methylsulfate fatty acid esters and from 1 to 1500 ppm methanol.
