Phenylbenzimidazole Sulfonic Acid

Explained

This ingredient is more commonly known as Ensulizole, a chemical sunscreen ingredient.

Ensulizole mainly protects UV-B (290-340 nm) but offers a little UV-A (320-400 nm) protection. It is often paired with less photo-stable sunscreen ingredients due to its photo-stability.

Due to it being water-soluble, Ensulizole helps give sunscreens a light and non-oily texture.

Ensulizole is approved worldwide:

  • 4% in the US, Australia, New Zealand, and South Korea
  • 8% in the EU
  • 3% in Japan
