Cocamidopropyl betaine (CAB-35) is a mild amphoteric surfactant widely used in personal care, household, and industrial applications. As a pale yellow, transparent, viscous liquid, it is a non-hazardous chemical and a bulk raw material in the daily chemical industry. Produced by companies such as Zhaoqing Liangpeng Biotechnology Co., Ltd., CAB-35 combines excellent foaming performance with low irritation, making it a preferred choice for formulators seeking both efficacy and safety.
One of the most notable properties of CAB-35 is its strong foaming ability. It produces fine, stable foam that enhances the sensory experience of cleansing products. Unlike some surfactants that collapse quickly, CAB-35 maintains foam volume over time, making it ideal for shampoos, body washes, and facial cleansers. Its foam is not only abundant but also delicate, providing a gentle yet effective cleaning action.

CAB-35 is renowned for its skin-friendly profile. It is significantly less irritating than many anionic surfactants, such as sodium lauryl sulfate. This makes it suitable for sensitive skin formulations, baby products, and daily-use personal care items. Its amphoteric nature allows it to reduce the irritation potential of other surfactants when used in combination, improving the overall safety of the final product.
A key advantage of CAB-35 is its compatibility with anionic, cationic, and nonionic surfactants. This versatility enables formulators to blend it into a wide range of systems without phase separation or loss of performance. Beyond compatibility, CAB-35 also acts as a thickener and antistatic agent. These secondary benefits reduce the need for additional additives, simplifying formulations and improving cost efficiency.
CAB-35 serves multiple sectors. In daily chemical cleansing, it is a core ingredient in shampoos, shower gels, and hand washes. In the textile industry, it functions as a softening agent. In oilfields, it is used as a foam flooding agent for enhanced oil recovery. Additionally, it finds use in household detergent formulations, where its mildness and foaming power improve cleaning performance. As a bulk raw material, CAB-35 continues to be a reliable and multifunctional solution for diverse industrial needs.
