Sunscreen Actives

Sunscreen agent that protects primarily against the sun’s UVB rays, providing only minimal UVA protection. Ensulizole protects the skin from wavelengths of UV light in the range 290 to 340 nanometers, whereas the UVA range is 320 to 400 nanometers. [1] For complete protection, this ingredient (as well as many other UVB-protecting sunscreen ingredients) must be paired with the UVA-protecting ingredients avobenzone, titanium dioxide, zinc oxide, or Mexoryl SX (ecamsule); outside the United States, it can also be paired with Tinosorb. [1,2]

Because ensulizole is water-soluble, it has the unique characteristic of feeling relatively light on skin; thus, it is often used in sunscreen lotions or moisturizers whose aesthetic goal is a non-greasy finish.
