| Uses | ensulizole is one of the chemical names for phenylbenzimidazole sulfonic acid. used as a sunscreen ingredient and also to protect a product from deterioration caused by uV light. |
| Uses | 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. |
| Definition | ChEBI: Ensulizole is a member of benzimidazoles. |
| General Description | 2-Phenyl-5-benzimidazolesulfonic acid has been reported as a UV filter and its removal from aerobically treated gray water by ozonation and adsorption onto activated carbon has been reported. It is a xenobiotic compound detected in gray water from houses and effluents of the biological treatment systems (aerobic, anaerobic, and combined anaerobic+aerobic). |
| Flammability and Explosibility | Non flammable |
