In the dynamic world of cosmetics and personal care, product stability and efficacy are paramount. Consumers increasingly seek formulations that not only perform but also offer superior protection from environmental aggressors, especially ultraviolet (UV) radiation. This is where advanced UV absorbers play a critical role. NINGBO INNO PHARMCHEM CO., LTD. specializes in providing high-quality chemical ingredients, including essential UV filters like 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid (CAS 4065-45-6), also known as Benzophenone-4 or BP-4.

The Challenge of UV Degradation

UV radiation from the sun can degrade the active ingredients in cosmetic products, leading to loss of efficacy, color changes, and altered textures. Furthermore, it poses a direct threat to skin health. Therefore, incorporating effective UV absorbers into formulations is not just a functional requirement but a safety imperative. The challenge for formulators often lies in finding ingredients that are compatible with water-based systems, stable under light and heat, and compliant with global regulations.

Introducing 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid (BP-4)

Our 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid stands out as a superior choice for cosmetic applications. Its key advantage is its excellent water solubility, which simplifies the formulation process for water-based products such as lotions, serums, shampoos, and styling gels. Unlike many oil-soluble UV filters, BP-4 integrates seamlessly into aqueous phases, eliminating the need for complex emulsification systems and ensuring uniform distribution within the product.

Broad-Spectrum Protection and Stability

This compound offers broad-spectrum UV protection, effectively absorbing both UV-A and UV-B rays. This dual action is crucial for comprehensive sun protection and for preventing the degradation of other ingredients within the formulation. Furthermore, BP-4 exhibits remarkable light and thermal stability. This means that the UV protection it provides remains effective over time, even when exposed to light and elevated temperatures, which is a significant advantage for product shelf-life and performance in diverse climates. As a premier UV absorber for cosmetics, its reliability is unmatched.

Regulatory Approval and Safety Profile

Safety and regulatory compliance are at the forefront of cosmetic ingredient selection. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid is approved by the FDA and is widely permitted for use in major global markets, including Europe, Japan, and China. Its low toxicity profile, with an LD50 of 3530 mg/kg in mice, further solidifies its position as a safe and dependable ingredient. For businesses looking to buy 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid manufacturer, NINGBO INNO PHARMCHEM offers a reliable source backed by quality assurance.
