trialkanolamides

Trialkanolamides are a class of nonionic surfactants derived from the reaction of fatty acids with alkanolamines. The most common are derived from coconut oil or palm kernel oil, which are rich in fatty acids, and diethanolamine or triethanolamine. These compounds have a dual nature, possessing both hydrophilic (water-loving) and lipophilic (oil-loving) properties, making them effective emulsifiers, foaming agents, and viscosity builders in various formulations.

In cosmetic and personal care products, trialkanolamides are widely used as foam boosters and stabilizers in shampoos, body washes, and liquid soaps. They contribute to a richer lather and a more luxurious feel. Their ability to thicken formulations also makes them useful in creams and lotions. They can also act as emulsifiers, helping to blend oil and water components in products.

Industrially, trialkanolamides find applications in metalworking fluids as corrosion inhibitors and lubricants. They are also used in textile processing and in the formulation of agricultural chemicals. The specific properties of a trialkanolamide depend on the length and type of fatty acid and the alkanolamine used in its synthesis. While generally considered safe for use in consumer products at approved concentrations, potential concerns regarding nitrosamine formation have led to regulatory scrutiny and the development of alternative ingredients in some applications.
