Parabens, like Methyl Paraben(C8H8O3) and Propyl Paraben (C10H12O3) are neutral esters, which inhibit the growth of bacteria and molds in many types of products with a very small dosage. They are effective in slightly alkaline as well as neutral or acidic media, in the range of pH 3 - 8. This proves very useful in many processes where the use of acidic preservatives or alkaline salts shows little inhibitory effects. Numerous studies have shown that parabens are safe for use as a preservative in the food, pharmaceutical, cosmetic, and toiletries industries.
