In the ever-evolving landscape of skincare and sun protection, understanding the active ingredients is paramount. Among the essential components that guard our skin against the damaging effects of ultraviolet (UV) radiation is 2-Phenylbenzimidazole-5-Sulfonic Acid. This article, brought to you by NINGBO INNO PHARMCHEM CO.,LTD., aims to shed light on this crucial UV filter, exploring its properties, applications, and why it's a valuable ingredient in your sun care formulations.

What is 2-Phenylbenzimidazole-5-Sulfonic Acid?

Also known by its INCI name, Ensulizole, 2-Phenylbenzimidazole-5-Sulfonic Acid is a synthetic organic compound classified as a UV filter. Its primary role is to absorb UV radiation, thereby preventing it from penetrating the skin and causing damage. Unlike many traditional sunscreen agents that are oil-soluble, this compound boasts remarkable water solubility. This unique characteristic makes it an excellent choice for formulators looking to create lightweight, aesthetically pleasing sunscreens that feel comfortable on the skin, particularly for those with combination to oily skin types.

Key Benefits and Properties

The efficacy of 2-Phenylbenzimidazole-5-Sulfonic Acid as a sunscreen agent is rooted in its specific properties:

  • UVB Protection: Its peak protection lies within the UVB range (280-320 nm). UVB rays are primarily responsible for sunburn and can also contribute to skin aging and cancer.
  • Photostability: It is considered relatively photostable, meaning it maintains its effectiveness when exposed to sunlight over time. This stability is crucial for ensuring long-lasting protection.
  • Synergistic Effects: While primarily a UVB absorber, it can also help to photostabilize other UV filters, enhancing the overall performance of a broad-spectrum sunscreen. This is why you'll often find it paired with UVA-absorbing ingredients.
  • Formulation Versatility: Its water solubility simplifies the formulation process, allowing for the creation of fluid emulsions and serums with a non-greasy finish. This makes it a popular choice for modern sun care products.

Applications in Personal Care

The versatility of 2-Phenylbenzimidazole-5-Sulfonic Acid means it finds its way into a wide array of personal care products. From daily facial moisturizers with SPF to dedicated sunscreens and after-sun care, its inclusion ensures that consumers receive reliable UV protection. The demand for effective and comfortable sun protection continues to grow, making ingredients like this highly sought after by cosmetic manufacturers.

Regulatory Status and Safety

Regulatory bodies worldwide have assessed the safety and efficacy of 2-Phenylbenzimidazole-5-Sulfonic Acid. In the United States, its use is approved up to 4% concentration in over-the-counter sunscreen products. In the European Union, the maximum permitted concentration is 8%. These approvals are based on extensive safety evaluations, demonstrating its low potential for irritation and sensitization.
