摘要： A fabric conditioning active composition comprising an esterquat mixture of quaternized mono-, di-, and tri-esters of alkanolamine in which the tri-esterquat content of the quaternized esterquat mixture is greater than 25% by weight of the esterquat mixture, and the combined di-esterquat and tri-esterquat content in the esterquat mixture is greater than 78% by weight of the esterquat mixture. Additionally, the free fatty acid content of the composition is greater than 1% by weight based on the weight of the esterquat mixture. The fabric conditioning active composition provides high viscosity when dispersed into water at low concentrations of 0.5% to 12%, without the need for additional polymeric thickeners or other thickening additives.

摘要： Provided are methods for decreasing the reaction time between an alkanolamine such as triethanolamine and a fatty acid alkyl ester such as, a triglyceride, a vegetable oil, a methyl ester, an ethyl ester, etc., a fatty acid, or a mixture thereof. The methods utilize a divalent zinc catalyst to facilitate and accelerate an esterification or transesterification reaction between the alkanolamine and the fatty acid, or fatty acid alkyl ester.
