Overview of Octabenzone

Octabenzone is a widely used UV absorber and light stabiliser applied in plastics, coatings, adhesives, and polymer manufacturing industries. It is particularly effective in protecting materials from ultraviolet (UV) radiation, helping to prevent discolouration, degradation, and loss of mechanical strength caused by prolonged sunlight exposure.

Chemically known as 2,2'-Dihydroxy-4-methoxybenzophenone, Octabenzone belongs to the benzophenone UV absorber family. Its molecular formula is C₁₄H₁₂O₄, and it typically appears as a light yellow crystalline powder with strong UV absorption properties.


Octabenzone is commonly incorporated into plastic products, industrial coatings, synthetic resins, and polymer systems to improve long-term durability and weather resistance. It plays an essential role in stabilising materials exposed to sunlight and harsh environmental conditions.

As a trusted chemical supplier and reliable distributor, ChemicalBull ensures a consistent supply for polymer and coating manufacturers. You may also like Benzophenone, Titanium Dioxide, Zinc Oxide, and Butylated Hydroxytoluene (BHT) for related UV stabilisation and polymer protection applications available on our website.
