Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S) is a chemical sunscreen agent that works by absorbing ultraviolet light. It has two peak absorption wavelengths at about 310 nm and 340 nm, which can effectively absorb UVA and UVB rays in the wavelength range of 280 - 400 nm, converting the absorbed light energy into other forms of energy, thereby protecting the skin from ultraviolet-induced damage.
It is the gold-standard UV filter for high-performance sunscreens. As a photostable, broad-spectrum absorber, Tinosorb S delivers unmatched UVA/UVB protection while maintaining exceptional formulation stability—making it ideal for daily wear sunscreens, anti-aging skincare, and luxury sun care products.
Effectively blocks ultraviolet rays from reaching the skin and reducing damage such as sunburn, tanning, and photoaging.
Excellent photostability ensures it hardly deteriorates in the presence of UV light during exposure.
Works well with both mineral and chemical filters. Improves the photostability of less-stable agents like avobenzone.
There is no strict fixed dosage. Usually, it is adjusted according to the formula design and the desired protection level of the product. In some sunscreen products, the dosage typically ranges from 2% to 3.5%.
Skincare Products: Moisturizers and hand creams for daily UV protection during work or activities.
Sunscreen Products: Sun lotions and sprays to achieve high SPF and PA values.
Multifunctional Cosmetics: BB creams, CC creams, and makeup primers providing both coverage and protection.
