Description
The salt form of the water-soluble chemical sunscreen, Ensulizole. What we wrote there (UVB filter with a peak protection at 306 nm), applies here as well.
In fact, the pure acid form (aka Phenylbenzimidazole Sulfonic Acid) can be incorporated into a sunscreen formula only if it is neutralized with a base (otherwise it is not water-soluble), so even if the acid form in on the ingredient list, what you have in the formula is a salt form, just like this one.
