The development of effective sunscreen formulations is a cornerstone of skin protection, and the choice of UV absorbers plays a critical role in achieving desired performance and consumer appeal. Water-based sunscreens have gained popularity due to their lightweight feel and ease of application, making ingredients like 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid (CAS No. 4065-45-6), commonly known as Benzophenone-4 or BP-4, highly sought after. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of this essential ingredient, facilitating innovation in water-based personal care products.

Benzophenone-4 is a unique water-soluble UV absorber, a property that makes it exceptionally well-suited for water-based sunscreen formulations. Traditional oil-soluble UV filters can be challenging to incorporate into entirely aqueous systems, often requiring emulsifiers or co-solvents. Benzophenone-4, however, dissolves readily in water, simplifying the formulation process and allowing for the creation of elegant, non-greasy textures that consumers prefer.

As a broad-spectrum UV filter, Benzophenone-4 effectively absorbs both UVA and UVB radiation. This dual action provides comprehensive protection against the full range of damaging UV rays, from those causing sunburn (UVB) to those contributing to skin aging (UVA). The efficacy of Benzophenone-4 ensures that water-based sunscreens can offer robust protection without compromising on feel or aesthetic appeal.

Furthermore, Benzophenone-4 is valued for its good light and heat stability. This characteristic is crucial for sunscreens, which are frequently exposed to sunlight and varying environmental temperatures. The stability of Benzophenone-4 ensures that the sunscreen maintains its protective efficacy over time, providing reliable defense for the skin.

The safety profile of Benzophenone-4 is another significant advantage. As an FDA approved sunscreen ingredient, it has undergone rigorous testing and meets stringent regulatory standards for cosmetic use. This approval, along with its acceptance in other major global markets, provides formulators with confidence in its safety for topical application. Its use in a wide array of personal care products, from lotions and gels to hairsprays and styling gels, further highlights its versatility and safety.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-quality Benzophenone-4 to support the growing demand for advanced sun protection products. By providing this crucial ingredient, we empower cosmetic manufacturers to develop innovative water-based formulations that offer superior UV defense, enhanced sensory appeal, and a strong safety record. The incorporation of Benzophenone-4 is a key strategy for brands aiming to excel in the competitive personal care market.

In conclusion, Benzophenone-4 is an indispensable ingredient for creating modern, water-based sunscreen formulations. Its unique water solubility, broad-spectrum UV absorption, excellent stability, and proven safety make it an ideal choice for manufacturers seeking to deliver effective and desirable sun protection products.
