alkanolamides

Alkanolamides are a class of nonionic surfactants derived from fatty acids and alkanolamines. They are characterized by the presence of both an amide group and a hydroxyl group within their molecular structure. These compounds are typically synthesized through the reaction of a fatty acid ester with an alkanolamine, such as monoethanolamine or diethanolamine.

The primary function of alkanolamides in various applications is to modify the properties of a formulation, particularly its foaming and thickening characteristics. They are widely utilized in personal care products, including shampoos, body washes, and liquid soaps, where they act as foam boosters, stabilizers, and viscosity builders. This enhances the lathering and texture of these products, contributing to a more desirable user experience.

Beyond personal care, alkanolamides find application in industrial and household cleaning products, such as dishwashing liquids and detergents. In these contexts, they contribute to improved detergency, emulsification of oils and greases, and foam control. Their mildness and compatibility with other ingredients make them versatile components in a range of surfactant systems. The specific properties and performance of an alkanolamide are influenced by the length of the fatty acid chain and the type of alkanolamine used in its synthesis.
