Tocofersolan (INN) or tocophersolan, also referred to as TPGS (for tocopherol polyethylene glycol succinate), is a synthetic water-soluble version of vitamin E. Natural forms of vitamin E are fat soluble, but not water-soluble. Tocofersolan is polyethylene glycol derivative of α-tocopherol that enables water solubility.

Tocofersolan is used as a vitamin E supplement or to treat vitamin E deficiency in individuals who cannot absorb fats due to disease.[3] On 24 July 2009 the European Medicines Agency approved tocofersolan under the trade name Vedrop 50 mg/ml oral solution for the treatment of vitamin E deficiency due to digestive malabsorption in paediatric patients with congenital or hereditary chronic cholestasis, from birth (in term newborns) to 16 or 18 years of age (depending on the region).[4]

Tocofersolan is also used in cosmetics and pharmaceuticals as an antioxidant.[5]
