Tinosorb S
What is Tinosorb S?
Tinosorb S, chemically known as bis-ethylhexyloxyphenol methoxyphenyl triazine, is a synthetic organic compound belonging to the triazine class of UV absorbers. Developed for cosmetic formulations, it serves mainly in sun protection products, daily moisturizers, and hair care items. This lipophilic ingredient functions by strongly absorbing ultraviolet radiation across a wide range from UVA to UVB wavelengths, then dissipating the energy harmlessly as heat without degrading. Its exceptional photostability prevents breakdown under sunlight, allowing it to maintain efficacy and even stabilize other UV filters in formulations. Additionally, its emollient nature contributes to skin and hair conditioning by forming a protective film that reduces friction, enhances smoothness, and improves product texture without greasiness. Commonly incorporated at effective levels in leave-on products, it supports high SPF ratings with minimal whitening effect.
