Polysorbate 80(HX2)™ is produced from 99% or higher oleic acid, developed and commercially manufactured using our proprietary technology. By employing advanced ethylene oxide addition methods and sophisticated purification processes, we achieve significant reduction of by-products and thorough removal of impurities. As a result, Polysorbate 80(HX2)™ contains exceptionally low levels of aldehydes, peroxides, and impurities such as highly unsaturated fatty acids that are easily oxidized and fatty acids with different carbon numbers. Polysorbate 80(HX2)™ is widely adopted by pharmaceutical companies around the world and is used as a stabilizer in various vaccines and antibody therapeutics.
Safety Profile
These characteristics contribute to its outstanding quality and safety profile. In preclinical studies, Polysorbate 80(HX2)™ triggered less histamine release from rat mast cells compared to conventional Polysorbate 80 formulations. An in vivo dog study further confirmed reduced histamine release, suggesting a lower incidence of allergic responses associated with our product. Due to these advantages, Polysorbate 80(HX2)™ has attracted significant attention worldwide.
Oxidative Stability and Formulation Benefits
Polysorbate 80(HX2)™ also exhibits remarkably high oxidative stability. Not only does it have low initial impurity levels, but it also minimizes the formation of impurities during storage and use. According to published literature on the impact of peroxides in Polysorbate 80 on protein formulations*, model protein formulations (such as IL-2 mutein) are less likely to denature when using Polysorbate 80 with low peroxide values, whereas significant denaturation occurs when using Polysorbate 80 with high peroxide values. Given that many pharmaceuticals are sensitive to peroxides, utilizing Polysorbate 80(HX2)™ ensures the necessary stability and quality of formulations, earning high praise from numerous pharmaceutical companies.
