Benzophenone-9

Benzophenone-9 (CAS 76656-36-5) is a water-soluble UV absorber that protects formulations and substrates from UV-induced degradation. Its water solubility distinguishes it from most benzophenone-class absorbers.

This unique property makes it suitable for aqueous systems where oil-soluble alternatives cannot be used. In personal care and cosmetics, it functions as a UV filter in water-based sunscreens, lotions, and hair care products.

It is particularly effective where broad-spectrum UVA protection is required. Coatings and ink formulators incorporate it into aqueous coating systems and printing inks to prevent photodegradation of colorants and binders.

This is especially useful in packaging applications where light exposure is a concern. Water-based adhesives and sealants benefit from its stabilizing effect, extending the service life of bonded substrates.

These materials are often exposed to outdoor or fluorescent light during use. It is also used in textile treatment formulations to protect dyed fabrics from UV fading and maintain color integrity over time.

The product is supplied as a powder or as a concentrated aqueous solution, depending on the supplier and application requirements. It is available in cosmetic-grade specifications for personal care.

These grades meet regulatory requirements for use across major global markets. Technical-grade material is sourced for industrial coating, ink, and adhesive applications requiring high performance and stability.
