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.

Octyl Methoxycinnamate Extra Pure

Primary Uses

Ultraviolet-B (UV-B) Filter in Sunscreen Formulations
- Serves as a primary organic UV filter to absorb harmful UV-B radiation (290-320 nm), thereby preventing sunburn and protecting skin from DNA damage. It is a foundational ingredient in most commercial sunscreens, lotions, and daily wear cosmetics with SPF.
Photostabilizer in Multi-Filter Sun Care Products
- Used to enhance the photostability of other, less stable UV filters (particularly avobenzone, a UV-A filter) in broad-spectrum formulations. By absorbing excess energy, it helps prevent the rapid degradation of other actives, maintaining the product’s Sun Protection Factor (SPF) over time.
UV Absorber in Cosmetic and Personal Care Products
- Incorporated into a wide range of cosmetic products beyond sunscreens, including foundations, BB creams, lip balms, and moisturizers, to provide daily protection against UV-induced skin aging and pigmentation.
Key Ingredient in After-Sun and Skincare Products
- Used in after-sun lotions and moisturizing creams designed for sun-exposed skin, where its protective function is combined with soothing and hydrating agents to aid skin recovery.

Secondary Uses

UV Stabilizer in Polymer and Coating Industries
- Added to plastics, varnishes, paints, and packaging materials (e.g., for cosmetics or food) to prevent UV-induced degradation. It protects polymers from yellowing, embrittlement, and loss of mechanical properties caused by prolonged sunlight exposure.
Reference Standard in Analytical Chemistry
- Used as a high-purity standard in Quality Control (QC) laboratories for the quantitative analysis of sunscreen products via techniques like High-Performance Liquid Chromatography (HPLC) to verify concentration, purity, and stability.
Research Compound in Photochemistry and Dermatology
- Studied in in vitroand ex vivo research to understand its interaction with UV light, its penetration kinetics into the skin, and its overall efficacy and safety profile as a topically applied chemical.
Additive in Industrial Adhesives and Sealants
- Incorporated into light-sensitive adhesives and sealants to prevent curing or degradation during storage and application, ensuring product performance and longevity when used in outdoor or well-lit environments.
