METHYL ACETYLAMINOBENZOATE

Description

Methyl Acetylaminobenzoate, also known as Meradimate, is a potent UV filter primarily used in sunscreen formulations and other skincare products designed to protect against sun damage. This organic compound belongs to the family of para-aminobenzoic acid (PABA) derivatives and functions as a UVB absorber, effectively shielding the skin from harmful ultraviolet radiation.

The ingredient's molecular structure allows it to absorb UV light in the 280-320 nm range, which corresponds to the UVB spectrum. This absorption helps prevent UV-induced DNA damage, premature aging, and skin cancer risks. Methyl Acetylaminobenzoate is particularly valued for its photostability, maintaining its protective properties even after prolonged sun exposure.

In formulations, Methyl Acetylaminobenzoate is often combined with other UV filters to achieve broad-spectrum protection. It is oil-soluble, making it compatible with various cosmetic bases and enhancing the water resistance of sunscreen products. The typical concentration used in skincare formulations ranges from 3% to 5%, depending on the desired SPF level and regulatory guidelines in different regions.
