Cocodiethanolamide (CDEA) is a coconut oil-derived compound used as a foaming agent, emulsifier, and thickener in personal care products. It enhances the texture and stability of shampoos, body washes, and liquid soaps, creating a rich, creamy lather. Known for its ability to improve the viscosity of formulations, CDEA also helps in effectively mixing oil and water components. It is a versatile and widely used ingredient in cosmetic and cleaning products.
