In the ever-evolving world of cosmetics and personal care, ensuring product efficacy and consumer safety is paramount. One of the most critical aspects of skincare formulation is protection against harmful ultraviolet (UV) radiation. While many UV filters are available, the demand for water-soluble options has surged, driven by the need for elegant formulations that are both highly effective and pleasant to use. This is where compounds like 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid, commonly known as Benzophenone-4 or Sulisobenzone (CAS 4065-45-6), play a vital role.

As a leading manufacturer and supplier, we understand the stringent requirements of the cosmetic industry. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid is a standout ingredient because of its unique water-solubility, a feature that simplifies formulation processes significantly. Unlike oil-soluble UV filters, this compound can be seamlessly integrated into aqueous-based systems such as lotions, serums, and even water-based sunscreens without requiring emulsification. This not only leads to lighter, less greasy textures but also allows for a more uniform distribution of the UV-blocking agent throughout the product.

The broad-spectrum protection offered by Benzophenone-4 is another key advantage. It effectively absorbs both UVA and UVB rays, which are responsible for premature aging, sunburn, and long-term skin damage. Its ability to absorb across this wide range makes it an indispensable component for achieving high SPF (Sun Protection Factor) ratings and robust UVA protection. For formulators looking to buy high-purity UV absorbers, partnering with a reliable supplier like us ensures that you receive a product with consistent efficacy and minimal impurities.

Furthermore, the regulatory landscape for cosmetic ingredients is rigorous. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid has a strong safety profile and is approved by major regulatory bodies, including the FDA in the United States, and is permitted for use in Europe, Japan, and China. This widespread acceptance provides manufacturers with confidence when sourcing this ingredient. For businesses seeking to purchase this essential UV filter, understanding its CAS number (4065-45-6) is crucial for accurate sourcing and quality assurance.

The stability of a UV filter is also critical for its performance over time. Benzophenone-4 exhibits excellent light and thermal stability, meaning it can withstand exposure to sunlight and varying temperatures without significant degradation. This ensures that the product maintains its protective capabilities throughout its shelf life. When considering your options to buy this chemical intermediate, remember that a stable ingredient is key to a stable and effective end-product.

In summary, the demand for water-soluble UV absorbers in cosmetics is driven by their formulation ease, broad-spectrum protection, safety, and stability. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid, available from reputable manufacturers and suppliers, stands as a prime example of an ingredient that meets these demands. If your company is looking to enhance its sunscreen and skincare lines, consider the benefits of incorporating this high-quality UV absorber.
