Bemotrizinol, or bis-ethylhexyloxyphenol methoxyphenyl triazine, is an organic UV filter found in over-the-counter sunscreen products. It primarily absorbs UV-A rays. Compared to older broad-spectrum chemical agents, bemotrizinol is more more fat soluble (oil soluble in cosmetic oils) to aid in efficacy and broad-spectrum activity. It is claimed to be photostable, which increases its onset of action and its efficiency in providing protection against UV-rays upon topical application. Bemotrizinol is commonly marketed as Tinosorb S and Escalol S.

Bemotrizinol is an active sunscreen agent used in Europe and Australia and will often be paired with less photostable UV blockers such as avobenzone, as the combination creates a much more stable sunscreen that will not degrade and lose its efficacy when exposed to sunlight. In Australia, we need to wear sunscreen every day due to our high rates of skin cancer, and the fact that bemotrizinol can absorb both UVA and UVB rays, providing protection from skin diseases while also not losing effectiveness is an important consideration to make when purchasing sunscreen. Software's Daily Sun Defence SPF50+ protects against both UVA and UVB rays, helping to prevent photoageing, sun spots, and some skin cancers. The lightweight formulation blends seamlessly into the skin, sitting nicely under makeup without leaving a white cast.
