Benzophenone

Benzophenone (CAS 119-61-9 ), also known by its FEMA 2134 designation in flavor applications, is an aromatic ketone used across coatings, polymer, and printing industries as a photoinitiator and UV stabilizer.

It initiates photopolymerization reactions when exposed to UV light, enabling rapid curing in surface coatings, inks, and adhesives. In UV-curable printing inks and packaging coatings, it acts as a Type II photoinitiator.

The compound absorbs UV radiation to trigger cross-linking and deliver fast, durable surface finishes. Polymer formulators incorporate it as a UV stabilizer in plastics to slow photodegradation and extend service life.

This is particularly effective for automotive and outdoor components. In adhesives and sealants, it supports UV-cure systems where thermal curing is impractical, reducing processing time on production lines.

The compound also functions as a fragrance fixative in select industrial and consumer formulations. In these specific applications, its regulatory status governs the permitted use levels for manufacturers.

Benzophenone is supplied as white crystalline flakes or powder. Technical and industrial grades are the most common commercial forms, with purity levels typically at 99% or above for standard industrial use.

Food-grade and flavor-compliant material is available for applications governed by specific guidelines. Our material meets rigorous quality benchmarks to ensure consistent performance across all chemical processing applications.
