Use

The antimicrobial activity of propylparaben is reduced considerably in the presence of nonionic surfactants as a result of micellization. Absorption of propylparaben by plastics has been reported, with the amount absorbed dependent upon the type of plastic and the vehicle. Magnesium aluminum silicate, magnesium trisilicate, yellow iron oxide, and ultramarine blue have also been reported to absorb propylparaben, thereby reducing preservative efficacy. Propylparaben is discolored in the presence of iron and is subject to hydrolysis by weak alkalis and strong acids.
