Product Description
What Is Lauryl Diethanolamide?
Lauryl Diethanolamide (LDEA) is a surfactant and emulsifying agent derived from lauric acid (a fatty acid found in coconut and palm kernel oil). Hair shampoos, body washes, and cleansers frequently contain it due to its exceptional foaming and mild cleaning properties.
Preparation Method:
LDEA is synthesized by reacting lauric acid with diethanolamine (DEA) in the presence of heat and an alkaline catalyst. The reaction produces lauryl diethanolamide and water as a by-product. The mixture is then neutralized, purified, and concentrated to obtain the final product.
LDEA is widely used in formulations where mildness is required, such as baby care products, skin cleansers, and shampoos. It enhances foam stability, improves the skin feel, and helps emulsify oils in water-based products.
