Zwitterionic surfactants, commonly classified as amphoteric, represent a sophisticated class of surface-active agents containing both positive and negative charges within the same molecular structure. Because their ionic state shifts in response to the pH of the system, they present a zero net charge at their isoelectric point. This chemical duality grants them unique features, such as exceptional compatibility with anionic, cationic, and nonionic compounds, along with superior skin compatibility and structural foam stability.
Modern personal care and industrial formulation designs increasingly demand mild, non-toxic, and high-foaming components. By combining zwitterionics with anionics, formulators create mixed micellar structures. This reduces the concentration of free surfactant monomers in solution, lowering skin irritation index values (assessed via Zein and HET-CAM testing) and maintaining deep cleansing capabilities.
As a leading supplier in the daily chemical raw materials industry, Suzhou Yuantairun Chemical Co., Ltd. is dedicated to delivering high-quality products and comprehensive one-stop services to support our customers in R&D, production, and supply chain optimization. Our mission is to drive innovation and efficiency in the global daily chemical industry by providing cutting-edge solutions tailored to our clients' needs.
Home Care & Cleaners
Uses SLES and AOS as core surfactants for superior cleaning and rich foam. Combined with CMEA thickener for optimal viscosity and improved temperature stability.
Personal Care & Clean Beauty
Features Sodium Cocoyl Glutamate (YG02-95) and Sodium Lauroyl Sarcosinate (LS-100N) for mild cleansing, ideal for sensitive skin. Formulated to meet clean beauty standards.
Premium Cosmetics
Combines amphoteric CAB-35 and non-ionic APG1214 for a rich, low-residue lather. Sulfate-free design reduces skin dryness, making it suitable for sensitive skin.
Industrial & Engineering Cleaning
Powered by LAS (Linear Alkylbenzene Sulfonate) and solvent EGDS for rapid breakdown of grease. Formulated with Alkaline Lipase for improved biodegradability.
Textile Care & Conditioners
Utilizes cationic surfactant 1631-70 (Cetrimonium Chloride) for improved softness and anti-static performance. Concentrated structure lowers shipping and packaging footprint.
The global surfactant industry is transitioning toward bio-based feedstocks and carbon-neutral processing. At Yuantairun, our R&D is focused on next-generation zwitterionic surfactants synthesized from renewable palm kernel oil, coconut fatty acids, and bio-based amines.
Transitioning from petrochemical monochloroacetic acid (MCA) reagents to sustainable intermediates, reducing trace dichloroacetic acid and monochloroacetic acid impurities down to <5 ppm.
Developing Sultaine systems with high thermal stability and compatibility in high-salinity brines, designed for Enhanced Oil Recovery (EOR) in challenging geological formations.
Coupling protein hydrolysates with fatty acid chlorides to produce mild, highly biodegradable surfactants that match sulfate-free performance profiles.
Operating from industrial hubs in Jiangsu province, Suzhou Yuantairun Chemical Co., Ltd. provides global supply stability through raw material vertical integration, automated reactors, and advanced quality assurance.
We maintain strategic reserves of critical feedstocks, protecting clients from pricing volatility and ensuring consistent production schedules.
Located near major shipping ports, our logistics network provides just-in-time delivery for raw materials and finished products directly to your production line.
Our testing facilities offer OEM and ODM customization, matching target viscosity, active matter density, and pH profiles for individual formulas.
In highly regulated markets like Europe (subject to REACH) and North America (subject to TSCA), consumer demand shifts toward sulfate-free, clean beauty products. Zwitterionic surfactants like Cocamidopropyl Hydroxysultaine (CSB) and Cocamidopropyl Betaine (CAB-35) serve as core foam stabilizers and viscosity modifiers in mild baby shampoos, facial washes, and body washes.
In oil fields with high temperatures and salinity, standard anionic surfactants can precipitate. Amphoteric molecules, especially sulfobetaines, perform effectively under extreme salinity and high thermal conditions, lowering interfacial tension and enhancing oil recovery rates.
Urban density in Asia-Pacific markets drives demand for concentrated household and industrial detergents. The low critical micelle concentration of our zwitterionics allows formulators to create space-saving, high-efficiency products that remain stable during temperature changes.
Whether you require bulk delivery, custom active concentration profiles, or localized regulatory documentation, Suzhou Yuantairun is here to help.
