Products Usage
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.
