Use
The antimicrobial activity of methylparaben and other parabens is considerably reduced in the presence of nonionic surfactants, such as polysorbate 80, as a result of micellization.However, propylene glycol (10%) has been shown to potentiate the antimicrobial activity of the parabens in the presence of nonionic surfactants and prevents the interaction between methylparaben and polysorbate 80. Incompatibilities with other substances, such as bentonite, magnesium trisilicate,talc,tragacanth,sodium alginate, essential oils,sorbitol,and atropine,have been reported. It also reacts with various sugars and related sugar alcohols. Absorption of methylparaben by plastics has also been reported; the amount absorbed is dependent upon the type of plastic and the vehicle. It has been claimed that low-density and high-density polyethylene bottles do not absorb methylparaben. Methylparaben is discolored in the presence of iron and is subject to hydrolysis by weak alkalis and strong acids.
