“…This observation is consistent with previous findings that monoester components of PS80 were hydrolyzed favorably. 13,17,18 The pattern of enzyme-mediated PS hydrolysis, however, was reported to be dependent on the type of enzyme, the order of esters (mono-, di-, or triester), the identity of hydrophilic head group, and the fatty acid ester tail. 27 Enzymatic hydrolysis has been identified as a primary degradation pathway in high protein concentration drug products.…”

“…15,16 However, the oxidized PS80 was found to not only maintain its CMC properties and protective effect against mAb aggregation, but also show an increase in its surface activity. 17 Therefore, the impact of polysorbate degradation via auto-oxidation may be protein specific or buffer dependent and needs to be examined carefully.…”

“…As an example, the moiety started to degrade after the elimination step of its physically adsorbed water, but it was not fully degraded, therefore it continued to decompose again in the second step until the complete degradation process had occurred [ 17 ]. Figure 4 C is the thermogram for T80 surfactant, showing two thermal events—a thermal loss at 121 and 406 °C with a value of 2.4 and 94.8%—which correspond to the attached water removal and polyoxyethylene (POE) chains, respectively [ 18 ].…”

“…In [28], two pathways of the degradation inside the body are discussed: enzymatic hydrolysis and oxidation, which are exemplified by nonionic surfactant polysorbate 80 bearing ester groups. It was reported that enzymatic hydrolysis of polysorbate 80 can be achieved by esterases and lipases at ng/mL concentrations and phospholipase B at 200 ppm.…”
