A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Oxybenzone (benzophenone-3, CAS 131-57-7) is an aromatic ketone that functions as an ultraviolet-light absorber and stabilizer. Established uses include UV stabilization of plastics and synthetic resins and service as a UV-absorber/UV-filter ingredient in personal-care formulations. Supplied in bulk to manufacturers.
Frequently Asked Questions
Is benzophenone-3 the same as oxybenzone?
Yes. Benzophenone-3 and oxybenzone are two names for the same compound, CAS 131-57-7, an aromatic ketone (C14H12O3). INCI listings use 'Benzophenone-3'; the common chemical name is oxybenzone.
What is benzophenone-3 used for?
It functions as an ultraviolet-light absorber and stabilizer. Established uses include UV stabilization of plastics and synthetic resins, photostabilization in coatings, and service as a UV-filter/UV-absorber ingredient in personal-care formulations.
What is the difference between benzophenone-3 and benzophenone-4?
Both are benzophenone-class UV absorbers but distinct compounds with different CAS numbers and solubility profiles: benzophenone-3 (oxybenzone, CAS 131-57-7) is oil-soluble, while benzophenone-4 (sulisobenzone) is sulfonated and water-soluble. Specify which grade you require on your RFQ.
What CAS and HS code apply to benzophenone-3 for import documentation?
CAS 131-57-7, molecular formula C14H12O3, HS classification 291450. Request the CoA and SDS with each lot to confirm assay, identity, and GHS handling data for your records.
How is bulk benzophenone-3 packaged and priced?
It is supplied in bulk to manufacturers; packaging (bags, drums) and pricing depend on grade and volume, so we quote per order. Submit a bulk RFQ with your target volume and we will return a quote along with current CoA and SDS.
