The cosmetic industry thrives on innovation, constantly seeking ingredients that offer enhanced performance, safety, and consumer appeal. Within the vast array of cosmetic components, UV filters are indispensable, protecting skin from sun damage and preserving product integrity. 2-Hydroxy-4-Methoxybenzophenone-5-Sulfonic Acid, widely known as Sulisobenzone or Benzophenone-4 (CAS 4065-45-6), is a prime example of such a crucial ingredient. NINGBO INNO PHARMCHEM CO.,LTD. is a supplier of this versatile cosmetic chemical.

Sulisobenzone's primary contribution to cosmetic formulations is its function as a broad-spectrum UV absorber. It effectively screens both UVA and UVB radiation, providing essential protection against sunburn, photoaging, and other sun-induced skin concerns. Its water-solubility is a key advantage for cosmetic chemists, allowing for its seamless integration into a wide variety of water-based products. This includes everything from everyday moisturizers and foundations with SPF to specialized sunscreens, lotions, and even hair care products that require UV protection to prevent color fading and damage.

The stability of Sulisobenzone is another significant benefit for cosmetic formulators. It exhibits good light and heat stability, meaning it remains effective even when exposed to sunlight or elevated temperatures during product storage or use. This characteristic is vital for ensuring that the product continues to offer reliable UV protection throughout its intended lifespan. Products fortified with Sulisobenzone can maintain their efficacy, offering consumers consistent protection against UV exposure.

From a formulation perspective, Sulisobenzone is appreciated for its compatibility with other cosmetic ingredients. It can be used in conjunction with other UV filters to create synergistic effects, achieving higher sun protection factors or broader spectral coverage. Its role as a photostabilizer is also invaluable; it helps to protect other light-sensitive ingredients within the formulation from degradation, thereby enhancing the overall stability and performance of the cosmetic product. This dual action—UV absorption and photostabilization—makes it a highly desirable ingredient.

Regulatory compliance is a critical consideration for cosmetic ingredients, and Sulisobenzone scores well in this regard. It is approved for use in cosmetics and sunscreens in many major markets, including the United States by the FDA, and is also permitted in Europe, Japan, and China, typically at concentrations up to 10%. This broad acceptance is a testament to its safety profile and efficacy, providing manufacturers with confidence in its use.

In conclusion, 2-Hydroxy-4-Methoxybenzophenone-5-Sulfonic Acid is more than just a chemical; it's a vital component that enhances the protective and stabilizing capabilities of modern cosmetic formulations. Its broad-spectrum UV absorption, water solubility, stability, and regulatory approval make it a cornerstone ingredient for brands committed to delivering high-quality, safe, and effective personal care products. NINGBO INNO PHARMCHEM CO.,LTD. ensures the availability of this essential cosmetic chemical for the industry's innovative needs.
