Octyl Methoxycinnamate Extra Pure is a high-purity organic compound widely used as a UV-B filter in sunscreen formulations and personal care products. Known chemically as Ethylhexyl Methoxycinnamate, it functions by absorbing ultraviolet light in the 280–320 nm range, thereby protecting skin from sunburn and photoaging.
In its Extra Pure form, OMC offers exceptional quality for cosmetic-grade applications, pharmaceutical formulations, and research requiring stringent purity levels. It is typically a clear, oily liquid with good solubility in oils and alcohols, making it ideal for incorporation into emulsions, creams, and lotions. Aside from its cosmetic uses, it is occasionally used in plastic and polymer stabilization where UV protection is needed. It should be stored in cool, dark conditions to maintain its stability and efficacy.
