Methylparaben is a methyl ester of p-hydroxybenzoic acid, a widely used broad-spectrum preservative used in personal care products, pharmaceuticals, and some foods. It is colorless and odorless, compatible with a wide range of cosmetic ingredients.
Methylparaben and other members of the parabens family are superior to all other organic acid-based preservatives thanks to stable efficiency in a wide pH range and other conditions. Another remarkable property of parabens is that their antimicrobial activity covers practically all the microorganisms responsible for spoiling cosmetic and pharmaceutical products.
Methylparaben is a standard preservative for cosmetics and pharmaceuticals, in general, a slightly acidic to a neutral reaction and whose pH cannot generally be subsequently altered. Because its effect is independent of the acidity of the product to be protected, it is particularly reliable in cases where, owing to an error, the pH of the substance is not adjusted to the correct level.
If used in recommended concentrations, Methylparaben has a low order of toxicity and ecotoxicity. It exhibits a broad and balanced spectrum of antimicrobial activity against germs, retaining efficacy across a pH range of 4 to 8. In combination with other parabens, Methylparaben potentiates their action and exhibits increased activity, allowing formulators to decrease concentrations (lower minimum inhibition concentration).Ingredient products
Methylparaben is a preservative of medium strength and generally adequate solubility in water. It is indispensable for the preservation of many cosmetics and pharmaceuticals. A combination of Methylparaben and Propylparaben is often the best solution.
