Cocodiethanolamide (CDE)
Cocodiethanolamide (CDE), also known as Coconut Diethanolamide or Cocamide DEA,
is a non-ionic surfactant derived from the reaction of diethanolamine with
fatty acids from coconut oil. It appears as a pale yellow to amber viscous
liquid and is used primarily as a foam booster, emulsifier, thickener, and
stabilizer in personal care and cleaning products. Common applications include
shampoos, body washes, liquid soaps, dishwashing liquids, and other detergents.
CDE enhances the viscosity and stability of formulations while providing a rich
and stable lather, making it a valuable ingredient in mild and effective
cleansing systems.
