Vitamin E TPGS (Tocofersolan) Suppliers and Factory in China - High-Quality Surfactant with Excellent Water Solubility
As a natural emulsifier, vitamin E TPGS can significantly improve the bioavailability of fat-soluble nutrients (such as coenzyme Q10, carotenoids, fish oil, etc.). Its micelle-forming ability helps these ingredients to be stably dispersed in the intestine and promotes absorption in the small intestine, which is especially suitable for people with weak digestive function (such as the elderly or postoperative patients). Studies have shown that TPGS can increase the absorption rate of certain fat-soluble ingredients by 2–5 times.
TPGS retains the strong antioxidant properties of vitamin E, can effectively remove free radicals, protect cell membranes from oxidative damage, and synergistically enhance immunity. Its water-soluble characteristics break through the traditional vitamin E absorption limitations, can directly reach the cellular aqueous environment, and achieve more efficient antioxidant defense, which is suitable for anti-aging, cardiovascular health and sports nutrition formulas.
TPGS is widely used in oral nutritional supplements (ONS) and medical foods to improve the delivery efficiency of fat-soluble vitamins (A, D, E, K), while improving product stability and avoiding stratification or degradation.
As an FDA-approved pharmaceutical excipient (GRAS certification), TPGS can improve the solubility and bioavailability of poorly soluble drugs, such as antifungal drugs (itraconazole) and anti-tumor drugs (paclitaxel). Its micelle encapsulation technology can reduce drug dosage and reduce liver and kidney toxicity.
In anti-tumor nanoformulations, TPGS as a carrier material can prolong drug circulation time, enhance tumor tissue permeability, and reverse multidrug resistance by inhibiting the function of P-glycoprotein efflux pump. Studies have shown that TPGS-modified nanoparticles can improve the efficacy of chemotherapy drugs by more than 50%, while reducing side effects such as hair loss and nausea.
TPGS performs well in oral solid dispersions, self-microemulsification preparations and transdermal drug delivery systems, helping the development of sustained-release, enteric-coated or topical drug delivery products and expanding the possibility of innovative drugs.
Vitamin E TPGS (D-α-tocopherol polyethylene glycol 1000 succinate) is a water-soluble derivative of natural vitamin E formed by esterifying α-tocopherol with polyethylene glycol (PEG) via a succinate bond. Unlike conventional fat-soluble vitamin E, TPGS is amphiphilic — it dissolves in both water and lipid environments — enabling superior bioavailability, emulsification, and broader formulation compatibility in both nutritional and pharmaceutical applications.
TPGS acts as a natural emulsifier by forming micelles in the gastrointestinal tract. These micelles encapsulate fat-soluble nutrients such as coenzyme Q10, carotenoids, and fish oil, allowing them to disperse stably in the aqueous intestinal environment and significantly enhancing their absorption in the small intestine. Research indicates that TPGS can increase the absorption rate of certain fat-soluble ingredients by 2–5 times compared to unformulated forms.
Yes. Vitamin E TPGS holds FDA GRAS (Generally Recognized As Safe) certification and is approved as a pharmaceutical excipient. It has been extensively studied and used in oral solid dispersions, nanoformulations, medical foods, and oral nutritional supplements. Its safety profile is well established in both human nutrition and drug delivery applications.
In anti-tumor nanoformulations, TPGS serves as a carrier material that prolongs drug circulation time in the bloodstream, enhances permeability into tumor tissue, and reverses multidrug resistance by inhibiting P-glycoprotein efflux pumps. TPGS-modified nanoparticles have been shown to improve chemotherapy drug efficacy by more than 50% while significantly reducing side effects such as hair loss and nausea.
Yes. TPGS demonstrates excellent performance in a variety of advanced drug delivery platforms including oral solid dispersions, self-microemulsifying drug delivery systems (SMEDDS), and transdermal drug delivery systems. This versatility supports the formulation of sustained-release, enteric-coated, and topical drug products, broadening the scope of innovative pharmaceutical development.
Vitamin E TPGS is particularly beneficial for individuals with compromised digestive function, such as the elderly, postoperative patients, or those with malabsorption conditions, since its emulsification properties dramatically improve fat-soluble nutrient uptake. It is also highly valuable for people seeking antioxidant support, cardiovascular health, immune enhancement, anti-aging benefits, or sports nutrition — as well as patients undergoing drug therapies that require improved bioavailability or targeted delivery.
