Tinosorb S (BEMT)

Tinosorb S (BEMT) — Broad-Spectrum UV Filter for Sunscreen Formulations

Tinosorb S, chemically known as BEMT (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine), is one of the most advanced and photostable broad-spectrum UV filters available for cosmetic sunscreen formulations. It provides exceptional protection against both UVA and UVB radiation, making it a preferred choice for professional formulators developing high-performance sun care products.

Unlike older UV filters that degrade under sunlight, Tinosorb S is highly photostable and also acts as a photostabilizer for other UV filters in the formula, improving the overall SPF performance of your sunscreen.
