The Characterization of Polysorbate

Current Protocols, 2022
AbstractPolysorbates (PSs), including PS20 and PS80, are non‐ionic surfactants widely used in the pharmaceutical industry to enhance drug solubility and stability. Despite their wide application, PSs are prone to degradation by either hydrolysis or oxidation in drug formulations during storage; therefore, a PS characterization method assessing protein ...

Autoxidation of Polysorbates

Journal of Pharmaceutical Sciences, 1978
Aqueous solutions of polysorbate 20 undergo autoxidation on storage, with the peroxide number increasing and subsequently decreasing again, the acidity increasing continuously, the pH and surface tension falling and tending to level off, and the cloud point dropping sharply until turbidity begins at room temperature.

CMC of Polysorbates

Journal of Pharmaceutical Sciences, 1974
The CMC of a series of polysorbates was determined using a surface tension method. The CMC values obtained did not vary to any appreciable extent from those determined by other techniques, indicating that the procedure adopted was reliable, simple, and fast. The application of the usual correction factors was not necessary in the calculation of the CMC

The Composition of NF-Defined Emulsifiers: Sorbitan Monolaurate, Monopalmitate, Monostearate, Monooleate, Polysorbate 20, Polysorbate 40, Polysorbate 60, and Polysorbate 80

Drug Development and Industrial Pharmacy, 1998
Using the analytical constants for sorbitan monolaurate, monopalmitate, monostearate, and monooleate given in the National Formulary (NF), calculations were carried out that indicated that these emulsifiers are esters of sorbitol mono- and dianhydrides. Contrary to the NF description, no significant amount of sorbitol ester was calculated to be present,
