生物活性
Cremophor EL, a polyoxyethylene castor oil derivative, is a nonionic surfactant. Cremophor EL is widely employed to improve dissolution and delivery of drugs.
性状
Viscous liquid
体外研究(In Vitro)
Cremophor EL is a widely used excipient. In the first 10 h, Cremophor EL at 5 mg/mL increases the impedance, then decreases it, and after 20 h of treatment, epithelial cell death is detected. Cremophor EL decreases cell viability and increases cell toxicity more than RH40. Both epithelial viability and monolayer integrity are seriously impaired at 10 to 50 mg/mL concentrations of Cremophor EL at 24-h treatment. Cremophor EL also enhances cell detachment. has not independently confirmed the accuracy of these methods. They are for reference only.
