Methylparaben is also known as methylparaben. Parabens were first used as food preservatives. After a series of explorations and studies, they were introduced into cosmetics as preservatives. Methylparaben has a strong antibacterial effect, and its most prominent antibacterial ability is against molds and yeasts, but it has a poor effect on some bacteria (Gram-negative bacteria, lactic acid bacteria), so it is often used in combination with other preservatives in cosmetics.
