At NINGBO INNO PHARMCHEM CO.,LTD., we are constantly exploring innovative ingredients that enhance product efficacy and user experience. One such compound that has garnered significant attention in the personal care industry is 2-Phenylbenzimidazole-5-Sulfonic Acid, often referred to by its INCI name, Ensulizole. This water-soluble organic compound is a highly effective UV filter, primarily recognized for its potent UVB absorption capabilities, with a lesser but still significant contribution to UVA protection.

The demand for high-performance sunscreens that offer reliable protection without compromising on texture and feel is ever-increasing. 2-Phenylbenzimidazole-5-Sulfonic Acid fits this requirement perfectly. Its water solubility allows it to be incorporated into the aqueous phase of emulsion systems, a departure from many oil-soluble UV filters. This characteristic results in formulations that feel lighter and less greasy on the skin, making it an ideal choice for daily-use moisturizers, serums, and lightweight sunscreens. The ability to achieve desired SPF values with this ingredient is also noteworthy; it exhibits a favorable use level versus SPF relationship and can significantly boost the overall SPF when combined with other UV absorbers.

Beyond its primary role in sun protection, the versatility of 2-Phenylbenzimidazole-5-Sulfonic Acid extends to its application as a photostabilizer. It helps protect the cosmetic formulation itself from deterioration when exposed to UV light, thereby extending the shelf life and maintaining the integrity of the product. This dual functionality underscores its value as a sophisticated cosmetic raw material.

The safety and efficacy of cosmetic ingredients are paramount. Regulatory bodies in various regions have approved its use in sunscreens, with permitted concentrations typically ranging from 4% in the United States to 8% in the European Union. Extensive research has been conducted on its safety profile, indicating low irritation and sensitization potential when used within recommended levels. As part of our commitment to providing high-quality ingredients, NINGBO INNO PHARMCHEM CO.,LTD. ensures that the 2-Phenylbenzimidazole-5-Sulfonic Acid we supply meets stringent quality standards, enabling formulators to create safe and effective products.

For brands looking to develop advanced sun care products, understanding the benefits of ingredients like 2-Phenylbenzimidazole-5-Sulfonic Acid is crucial. Its contribution to both protection and aesthetics makes it a valuable asset in the formulation chemist's toolkit.
