EMPIGEN ® CBET is a 30% aqueous solution of coco-betaine. It's an amphoteric surfactant compatible with anionic, non-ionic, cationic and other amphoteric surfactants. It is stable over a wide pH range, thus providing the formulator with a flexible ingredient for use in many applications. Its use can give formulation and performance benefits in terms of abundant stable foam, superior foaming and cleansing in the presence of soap and hard water and ease of viscosity adjustment. Coco-betaine may be advantageous compared to many other amphoteric surfactants when formulating colourless or low colour products. Coco-betaine is often used in conjunction with primary surfactants, such as sodium laureth sulfate, where it helps to improve the mildness as well as boosting the viscosity and foam characteristics of the formulation. A ratio of 3:1 anionic: betaine is typically used, although levels up to 1:1 increase the performance. It may also be used to provide a mild conditioning effect.
