Abstract

See full text

Esteramine compositions and their derivatives are disclosed. The esteramines comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a tertiary alkanolamine. Derivatives made by quaternizing, sulfonating, alkoxylating, sulfating, and/or sulfating the esteramines are also disclosed. In one aspect, the ester derivative of the C10-C17 monounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The esteramines and derivatives are valuable for a wide variety of end uses, including cleaners, fabric treatment, hair conditioning, personal care (liquid cleansing products, conditioning bars, oral care products), antimicrobial compositions, agricultural uses, and oil field applications.
