Sorbitan trioleate

Sorbitan trioleate is an orally active nonionic surfactant with low toxicity (LD≥200 mg/kg). Sorbitan trioleate can be used as an excipient, such as surfactant, emulsifier, lubricant, wetting agent, dispersant, thickener, defoamer. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs[1][2].
