In the cosmetics industry, Fumaric Acid is used primarily as a buffering agent. Its function is to maintain the desired pH level in a product, ensuring that the product remains stable, effective, and safe for use on the skin.

It is typically found in concentrations ranging from 0.1% to 1%, depending on the formulation and intended use of the cosmetic product.
