NINGBO INNO PHARMCHEM CO.,LTD. understands the critical need for effective sun protection in today's world. The sun emits ultraviolet (UV) radiation, comprising UVA and UVB rays, both of which can cause significant damage to the skin and other materials. UVA rays penetrate deeper, contributing to premature aging and wrinkles, while UVB rays are primarily responsible for sunburn and skin cancer. Therefore, incorporating broad-spectrum UV protection into personal care products is not just beneficial, but essential.

One of the most vital components in achieving broad-spectrum UV protection is the inclusion of effective UV absorbers. These chemical compounds work by absorbing UV radiation and dissipating it as heat, thereby preventing it from reaching and damaging the skin. Among these, Benzophenone-4, also known chemically as 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid (CAS No. 4065-45-6), stands out for its remarkable properties.

This water-soluble UV absorber offers a unique advantage: it provides comprehensive protection across the UVA and UVB spectrum. This means it can effectively shield the skin from the aging effects of UVA rays as well as the burning effects of UVB rays. The broad-spectrum UV filter capabilities of Benzophenone-4 make it a preferred choice for formulators aiming to create high-SPF sunscreens and daily-use cosmetic products that offer maximum protection.

Beyond its broad-spectrum coverage, 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid is highly valued for its excellent light and heat stability. This characteristic ensures that the UV protection offered by a formulation remains consistent and effective, even when exposed to sunlight and varying temperatures. This stability is crucial for the longevity and performance of sunscreens, lotions, and hair care products, where consistent UV shielding is paramount.

The approval of Benzophenone-4 by regulatory bodies such as the FDA, along with its acceptance in European and Japanese markets, underscores its safety and efficacy. As an FDA approved sunscreen ingredient, it provides formulators with a trusted component that meets stringent safety standards. Its low toxicity profile, with a reported oral LD50 in mice of 3530 mg/kg, further reinforces its suitability for widespread use in personal care applications.

The water-soluble UV absorber nature of 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid is another significant advantage. This property allows for easy incorporation into a variety of formulations, particularly those with a water base, such as styling gels, shampoos, and lotions. This ease of formulation contributes to its popularity among cosmetic chemists seeking to develop innovative and effective personal care products.

For businesses looking to enhance their product lines with superior sun protection, partnering with a reliable supplier for high-quality ingredients is key. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing these essential components, ensuring that formulators have access to the best materials to create safe and effective products. Investing in ingredients like 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid is an investment in consumer well-being and product performance, making it a smart choice for brands aiming to lead in the personal care market.
