Cerium Dioxide

thoughtful mini-steps: Cerium Dioxide (CAS 1306-38-3 ), also known as ceria, is a rare earth oxide sourced for its UV-absorbing and surface-modifying properties across industrial and cosmetic applications. It functions primarily as a polishing agent, UV filter, and catalytic additive in manufacturing processes. In personal care and cosmetics, ceria is incorporated into sunscreen and UV-protective formulations. It absorbs ultraviolet radiation, offering an inorganic alternative to organic UV filters. Printing and packaging manufacturers use it as a polishing compound for optical glass and precision-coated surfaces. This improves surface finish on print rollers and optical components. As a pigment additive, it contributes to color stability and surface uniformity in specialty coatings and ink systems. Its biocidal and antimicrobial properties are also being leveraged in functional packaging materials. These materials are designed to extend shelf life or inhibit surface microbial growth. Cerium Dioxide is supplied as a fine white powder in varying particle sizes, including nanoscale grades suited to cosmetic and high-performance coating applications. Standard technical and high-purity grades are available, with purity levels typically ranging from 99% to 99.99% depending on end-use requirements. Buyers should confirm particle size distribution and purity certification when sourcing for UV filter or polishing applications, as these parameters directly affect performance.
