Ultraviolet (UV) radiation from sunlight poses a significant threat to the stability and longevity of many commercial products, ranging from personal care items to industrial coatings. Understanding the science behind UV protection and the role of specific ingredients like Benzophenone-9 (BP-9) is crucial for formulators aiming to deliver high-performance and durable goods.

Benzophenone-9, chemically known as Disodium 2,2'-dihydroxy-4,4'-dimethoxybenzophenone-5,5'-disulfonate and identified by CAS number 76656-36-5, is a highly effective UV absorber. Its molecular structure, characterized by conjugated double bonds and aromatic rings, allows it to absorb UV radiation, particularly within the UV-B spectrum (280-320 nm). Upon absorbing a UV photon, the molecule enters an excited state, then dissipates this energy as heat, returning to its ground state without undergoing significant degradation itself. This photophysical process effectively shields the surrounding material from UV damage.

A key characteristic that sets BP-9 apart is its exceptional water solubility. This property makes it an ideal additive for water-based formulations, including many cosmetics, water-soluble inks, and paints. Unlike oil-soluble UV filters that require complex emulsification systems for aqueous bases, BP-9 integrates seamlessly, simplifying the formulation process and ensuring uniform distribution of UV protection. When you buy UV Absorber BP-9 manufacturer in China, you are accessing a product designed for optimal performance in aqueous environments, contributing to a better water-soluble UV absorber price.

The efficacy of BP-9 in protecting products from UV-induced color fading, degradation of active ingredients, and material breakdown is well-documented. For instance, in cosmetics, it safeguards formulations from changes in color and scent, especially when stored in transparent packaging. Inks and coatings benefit from its ability to maintain vibrant colors and structural integrity under light exposure. The technical data, such as a K-value (a measure of UV absorbance) of ≥16.0 or higher, indicates its potent UV filtering capabilities. Identifying reputable sources for BP-9 CAS 76656-36-5 for inks is crucial for formulators.
