ChEBI: Methylparaben is a 4-hydroxybenzoate ester resulting from the form al condensation of the carboxy group of 4-hydroxybenzoic acid with metha nol. It is the most frequently used antimicrobial preservative in cosmetics. It occurs naturally in several fruits, particularly in blueberries. It has a role as a plant metabolite, an antimicrobial food preservative, a neuroprotective agent and an antifungal agent.

2.What is it used for?

Methylparaben is the ester of methyl alcohol and p-hydroxybenzoic acid, It is a bacteriostatic agent and preservative that was added to local anesthetic agents without vasoconstrictors before 1984 to prevent bacterial growth. Allergic reactions developed from repeated exposures to parabens led to the removal of this agent from dental anesthetic solutions. Similar products produced by similar production methods, like ethyl p-hydroxybenzoate (paraben B) and propyl p-hydroxybenzoate (Nepalese c), are also disinfectant preservatives. The products are irritating to the skin.

Methyl 4-hydroxybenzoate is used as an anti-fungal agent. It is also used as a preservative in foods, beverages and cosmetics. It acts as an inhibitor of growth of molds and to lesser extent bacteria and as a vehicle for ophthalmic solution.

Methylparaben and propylparaben are the most common of these. parabens is one of the most commonly used group of preservatives in the cosmetic, pharmaceutical, and food industries. Parabens provide bacteriostatic and fungistatic activity against a diverse number of organisms, and are considered safe for use in cosmetics, particularly in light of their low sensitizing potential. An evaluation of preservatives for use in leave-on cosmetic preparations lists parabens among the least sensitizing. The range of concentrations used in cosmetics varies between 0.03 and 0.30 percent, depending on the conditions for use and the product to which the paraben is added.
