Discover premium-grade chemical ingredients engineered for stability, performance, and dermatological safety across multiple commercial and industrial applications.
Cocamidopropyl Betaine (CAB-35), registered under CAS No. 61789-40-0, represents one of the most commercially significant amphoteric surfactants in modern industrial chemistry. Characterized by its unique zwitterionic structure, CAB-35 exhibits dual charge properties depending upon the pH of the system in which it is formulated. Under acidic environments, it acts as a cationic surfactant; under alkaline environments, it behaves as an anionic surfactant; and it maintains an isoelectric range where it functions neutrally.
For formulation engineers, this zwitterionic profile yields exceptional multi-functional advantages. CAB-35 is not merely a secondary surfactant or a simple foam booster. It acts as an irritation mitigation agent, significantly reducing the harshness associated with primary anionic surfactants such as Sodium Laureth Sulfate (SLES) or Sodium Lauryl Sulfate (SLS). It operates at the micellar level, inserting itself into the anionic micelles to increase their size and reduce their overall charge density, which dramatically minimizes their capability to penetrate and disrupt the stratum corneum of the human skin.
"By utilizing Yuantairun's high-purity Cocamidopropyl Betaine 35%, formulators can create products that achieve high foam volumes while preserving the skin's lipid barrier, striking a balance between cleansing efficacy and dermatological safety."
Beyond dermatological safety, CAB-35 provides excellent conditioning properties for hair and skin. The molecular presence of the fatty alkyl chains provides mild emolliency, leaving a smooth, non-stripping sensation after rinsing. Furthermore, CAB-35 exhibits robust hard water tolerance and shows excellent compatibility with anionic, cationic, and other non-ionic surfactants, establishing it as a foundational component in modern chemical blending.
The global market for amphoteric surfactants is experiencing a steady increase, driven by a consumer shift toward mild, bio-based, and sulfate-free formulations. In markets such as Europe and North America, regulatory scrutiny over primary anionic surfactants and their impurities—such as residual 1,4-Dioxane—has forced product developers to redesign formulations. CAB-35 has emerged as a key ingredient in these redesigned systems, acting as a primary co-surfactant to maintain high foam volume and viscosity while meeting strict environmental standards.
Concurrently, industrial sectors in rapidly expanding economies within the Asia-Pacific region and Latin America are modernizing their consumer product manufacturing processes. The demand for daily chemical raw materials has shifted from raw volume to performance consistency. Major consumer goods giants and regional private labels alike require raw material partners that can guarantee not only technical compliance—such as low amine values and minimum salt generation—but also long-term supply chain reliability.

The dynamics of industrial sourcing are also changing due to green certification requirements. Companies seeking certifications such as EU Ecolabel, Nordic Swan, or USDA BioPreferred are auditing their supply chains for raw materials derived from RSPO-certified palm oil or sustainably sourced coconut oil. Meeting these requirements demands an advanced level of supply chain transparency and regulatory documentation from chemical manufacturers.
Sourcing Cocamidopropyl Betaine 35% from Chinese chemical manufacturers like Suzhou Yuantairun Chemical Co., Ltd. offers significant strategic advantages. These advantages go beyond simple labor cost differences, encompassing advanced production technology, integrated supply chains, and superior logistics infrastructure.
China's chemical manufacturing industry has undergone massive structural reforms, focusing on environmental sustainability and high technology. Modern plants utilize automated, continuous reaction technologies that minimize batch-to-batch variation. By utilizing closed-loop DCS (Distributed Control System) automation, Yuantairun regulates reaction kinetics, temperature, and feeding rates. This control ensures the complete conversion of monochloroacetic acid (MCA) and dimethylaminopropylamine (DMAPA), resulting in exceptionally low levels of toxic residuals and high-purity final products.
Additionally, the geographic clustering of raw material suppliers in China's industrial parks offers unique logistical advantages. The direct pipelines and short-haul transport routes for raw materials such as coconut fatty acids and ethylene oxide significantly reduce processing lead times. This allows Yuantairun to maintain a reliable supply chain even during periods of global logistics volatility.
