Paraben methyl ester, also known as hydroxyphenylate, Paraben lipids were initially used as food preservatives, and after a series of exploration studies, they were introduced into cosmetics as preservatives. Hydroxyphenylate has a strong antibacterial effect, among which the most prominent Chemicalbook is the antibacterial ability of mold and yeast, but for some bacteria (gram-negative bacteria, lactic acid bacteria) the effect is poor, so it is often used with other preservatives in cosmetics.
Methyl paraben is mainly used as a bactericidal preservative in organic synthesis, food, cosmetics, medicine, and also used as a feed preservative.
