Polysorbate 20, chemically known as polyoxyethylene (20) sorbitan monolaurate, is a structurally complex non-ionic surfactant. Its molecular composition comprises a hydrophilic head consisting of polyoxyethylene chains (averaging 20 recurring units of ethylene oxide) combined with a lipophilic tail derived from lauric acid (a 12-carbon saturated fatty acid). This unique composition yields a Hydrophilic-Lipophilic Balance (HLB) value of 16.7. This high HLB value categorizes Polysorbate 20 as an exceptional oil-in-water (O/W) emulsifier and solubilizer. It functions by forming robust micelles that encapsulate hydrophobic materials, including essential oils, lipophilic vitamins (A, D, E, K), and fragrances, rendering them soluble in aqueous solutions.
The Critical Micelle Concentration (CMC) of Polysorbate 20 is approximately 60 mg/L (or 0.05 mM at 25°C). Above this concentration, individual surfactant monomers spontaneously organize into spherical micelles. This low CMC value allows the material to retain its solubilizing capacity even under significant dilution, a critical performance metric for personal care, cosmetic, and pharmaceutical systems.
In the global industrial arena, Polysorbate 20 is a foundational ingredient across multiple major sectors:
Established in 2010, Suzhou Yuantairun Chemical Co., Ltd. has developed into a premium developer, manufacturer, and exporter of daily chemical raw materials and specialized surfactants. We supply critical components that drive innovation, manufacturing stability, and environmental sustainability in the global cosmetics, home care, and industrial processing industries.
Our core mission is to support our clients through advanced R&D, rigorous chemical synthesis, and customized supply chain optimization. By bridging chemical raw materials with high-performance downstream formulations, we help brands and manufacturers achieve consistent product quality, clear solution dynamics, and regulatory compliance.
Evaluating clean manufacturing pathways, trace impurity control, and bio-based sourcing.
Our raw material feedstock relies on sustainably harvested, RSPO-certified palm and coconut fatty acids, preventing ecological displacement and reducing raw material carbon footprint.
We use narrow-range alkoxylation catalysts to secure precise target EO distributions, minimizing standard deviations in hydrophilic polyoxyethylene chain lengths.
Advanced vacuum stripping and post-reaction purging processes decrease free ethylene oxide and 1,4-dioxane impurities to below 1 ppm, exceeding global cosmetic and pharmaceutical regulatory standards.
We are advancing our manufacturing roadmap to source bio-derived ethylene glycol to synthesize a 100% bio-based Polysorbate 20, eliminating dependency on fossil fuel feedstocks.
