Methyl Paraben is an extra fine white powder with faint odor that is non-hygroscopic and generally recognized as safe (GRAS) for use as a preservative in foods. For over 50 years this neutral ester of para-hydroxybenzoic acid has functioned as an excellent bacteriostatic and fungistatic agent at low concentration against a wide range of organisms. It is stable and active from pH 3 to 8, and is often used in conjunction with other additives (e.g., EDTA or its salts, Quaternium-15, Diazolidinyl Urea, Propylparaben) for synergistic effects. In personal care products, Methylparaben and Propylparaben have typically been used in combination (0.2% Methylparaben and 0.1% Propylparaben, with levels adjusted to specific circumstances). Methyl Paraben has limited solubility in water, so presolubilization can reduce dissolution time and therefore batching time. The preference for parabens continues due to their 50-year history of safety and reliability.
Methyl Paraben complies with the following regulations based on the ICH harmonization: USP/NF, FCC, BP, EP, and JP.
