In the competitive landscape of the personal care industry, the development of effective and aesthetically pleasing sunscreens is paramount. One ingredient that has consistently proven its value is 2-Phenylbenzimidazole-5-sulfonic Acid (CAS 27503-81-7), often referred to by its INCI name, Ensulizole. As a leading manufacturer and supplier of specialty chemicals, we understand the critical role this compound plays in modern cosmetic formulations. If you are looking to buy high-quality sunscreen active ingredients, understanding the benefits of this compound is key.

Understanding the UV Spectrum and Protection Needs

The sun emits ultraviolet (UV) radiation, broadly categorized into UVA and UVB rays. While both are harmful, UVB rays are primarily responsible for sunburn, whereas UVA rays penetrate deeper, contributing to premature skin aging and increasing the risk of skin cancer. Effective sunscreens need to provide broad-spectrum protection, shielding the skin from both types of radiation. 2-Phenylbenzimidazole-5-sulfonic acid excels in this regard, particularly in its strong absorption of UVB radiation and a portion of the UVA spectrum.

Why Choose 2-Phenylbenzimidazole-5-sulfonic Acid?

As a manufacturer, we recognize the unique advantages that 2-Phenylbenzimidazole-5-sulfonic acid offers to formulators:

  • Water Solubility: Unlike many oil-soluble UV filters, this compound is water-soluble. This characteristic allows for the creation of lighter, non-greasy formulations, which are highly desirable for consumers, especially those with oily or combination skin types. It integrates seamlessly into the water phase of emulsions, enhancing the overall sensory experience of the product.
  • Photostability: A critical factor in sunscreen efficacy is photostability – the ability of the UV filter to maintain its protective properties upon exposure to UV light. 2-Phenylbenzimidazole-5-sulfonic acid demonstrates excellent photostability, meaning it effectively protects the skin over extended periods and can even help stabilize other UV filters in the formulation, preventing their degradation. This directly impacts the longevity and reliability of the SPF claims.
  • Formulation Versatility: Its water solubility and compatibility with other cosmetic ingredients make it a versatile component. It can be used in a wide array of products, from daily moisturizers with SPF to dedicated sunscreens, lotions, gels, and creams. For those seeking a reliable supplier for cosmetic grade ingredients, our product meets stringent purity standards.
  • SPF Boosting Capabilities: When combined with other UV filters, 2-Phenylbenzimidazole-5-sulfonic acid has been shown to synergistically boost the overall Sun Protection Factor (SPF) of sunscreen formulations. This allows formulators to achieve higher protection levels more efficiently.
