Exploring the Versatile Applications of Tinosorb M in UV Protection and Photonics

Tinosorb M—formally known by its chemical designation 2,2'-Methylenebis(6-(benzotriazol-2-yl)-4-tert-octylphenol)—is a multifunctional compound with growing relevance across multiple industries. With the CAS number 103597-45-1 and also marketed under the product name Ultraviolet Absorbent UV-360, Tinosorb M is primarily recognized for its exceptional performance as a UV stabilizer and filter.

A Reliable UV Filter in Sunscreens

In the personal care industry, Tinosorb M is frequently used in the formulation of sunscreens. It functions by absorbing and scattering both UVA and UVB radiation, offering broad-spectrum protection that enhances product safety and efficacy. Its relatively low toxicity profile and low irritation potential make it an ideal ingredient for sensitive skin formulations.

Functional Role in Polymers and Resins

Beyond cosmetics, Tinosorb M is a trusted light stabilizer in polymers and resins. It protects synthetic materials from UV-induced degradation, thereby extending product lifespan and maintaining physical integrity in outdoor applications. Its granular crystalline form, ranging from white to light yellow, allows for easy dispersion in manufacturing processes.

Applications in Organic Electronics

An emerging and promising application of Tinosorb M is in photo-luminescent dyes used in organic electronics. These materials benefit from UV-stable environments to prevent performance loss over time. Tinosorb M supports this by safeguarding delicate components from photodegradation.

With a molecular formula of C41H50N6O2 and molecular weight of 658.87 g/mol, Tinosorb M’s structure enables it to absorb high-energy UV rays, stabilize materials, and support product durability. Its multifunctional nature positions it as a valuable compound in industries spanning cosmetics, manufacturing, and electronics.
