Abstract
Esterquat compositions are disclosed that comprise, based on the weight of the composition, 0% to about 70% by weight of a solvent, and about 30% to 100% by weight of a mixture comprising about 50% to about 80% by weight, based on the weight of the mixture, of esterquats and about 20% to about 50% by weight, based on the weight of the mixture, of mono- and diglycerides. The esterquat compositions can be prepared by the direct esterification of a natural oil with an alkanolamine, followed by quaternization in the presence of the solvent. The esterquat compositions can be formulated into hair care compositions that provide improved wet and dry combing properties.
