Coco Amide DEA (CAD) is a chemical compound derived from coconut oil and diethanolamine that is commonly used as a foaming agent and thickener in personal care and household products. It helps to create a rich and creamy lather in products such as shampoos, body washes, and facial cleansers while also providing moisturizing and emulsifying properties. While there has been some controversy surrounding its safety, CAD has been approved for use in cosmetics by regulatory agencies.
