Drometrizole Trisiloxane
What is Drometrizole Trisiloxane?
Drometrizole Trisiloxane is a synthetic organic compound belonging to the benzotriazole family, modified with a trisiloxane chain for enhanced solubility in oils. Developed specifically for cosmetic formulations, it serves as an ultraviolet absorber primarily in sun protection products like lotions, creams, and sprays. In formulations, it functions by selectively absorbing damaging UVA rays in the 320-400 nm range, converting the absorbed energy into harmless heat that dissipates without harming the skin. This lipophilic nature allows it to integrate seamlessly into water-resistant and emollient-based products, contributing to even coverage and stability. Known for its photostability, it maintains efficacy under prolonged sun exposure without breaking down into reactive byproducts. Regulatory bodies in regions like the EU have evaluated it for use in sunscreens, often paired with other filters for comprehensive protection.
