phenylbenzimidazole sulfonic acid (2-phenyl-5-benzimidazolesulfonic acid; 2-phenylbenzimidazole-5-sulfonic acid, ensulizole) is one of 21 FDA-approved sunscreen chemicals for uVB absorption. It has an approved usage level of up to 4 percent in the united States and up to 8 percent in the european union. When combined with a proper base, it becomes a water-soluble sunscreen. It exhibits a very effective use level versus SPF relationship when compared to other sunscreen chemicals. In addition, when combined with other uVB absorbers, it seems to significantly boost SPF. It can also help protect a product from deterioration when exposed to uV light. Also considered excellent for use in clear sunscreen gels.

Uses

Phenylbenzimidazole sulfonic acid or ensulizole is a water-soluble UVB absorber that can be utilized in the water phase of emulsion systems, in contrast to most oil-soluble sunscreen ingredients, allowing for a less greasy, more aesthetically pleasing formulation such as a daily use moisturizer containing sunscreen. Phenylbenzimidazole sulfonic acid boosts the SPF of organic and inorganic sunscreens. It can also be used in clear gels owing to its water solubility.
