TEREPHTHALYLIDENE DICAMPHOR SULFONIC ACID

Description

Terephthalylidene dicamphor sulfonic acid, also known as Mexoryl SX, is a potent photostable UVA filter widely used in advanced sunscreen formulations. This water-soluble compound offers broad-spectrum protection against harmful ultraviolet radiation, with particular efficacy in the UVA range. Its unique molecular structure allows it to absorb UV rays and convert them into harmless heat energy, effectively shielding the skin from photodamage.

Mexoryl SX demonstrates excellent photostability, maintaining its protective properties even after prolonged sun exposure. This characteristic makes it an invaluable ingredient in sunscreens designed for extended outdoor use. The compound's water-solubility enhances its compatibility with various cosmetic formulations, allowing for lightweight, non-greasy textures.

Clinical studies have shown that terephthalylidene dicamphor sulfonic acid significantly reduces UV-induced skin damage, including premature aging and hyperpigmentation. Its low potential for skin irritation makes it suitable for sensitive skin types. When combined with other UV filters, Mexoryl SX contributes to achieving high SPF ratings while providing comprehensive UVA protection. Regulatory bodies in numerous countries have approved its use in sunscreen products, recognizing its efficacy and safety profile.
