Product Description
Amines, N-tallow alkyltrimethylenedi-, oleates is a versatile chemical compound with a wide range of industrial and cosmetic applications. It is a salt formed from the reaction of tallow-derived diamines and oleic acid, resulting in a mixture with variable composition based on the fatty acid profile of tallow. Amines, N-tallow alkyltrimethylenedi-, oleates functions as a surfactant, corrosion inhibitor, and emulsifier in industrial applications such as metalworking fluids, coatings, and lubricants. In the cosmetic industry, it serves as a conditioning and emulsifying salt, derived from animal fat and vegetable oil, making hair and skin feel soft, smooth, and manageable. It is also used as a pigment dispersant and wetting agent. Known by various synonyms including N-tallow-1,3-diaminopropane dioleate and Duomeen TDO, Amines, N-tallow alkyltrimethylenedi-, oleates is a key ingredient in many formulations due to its multifunctional properties.
