Ethylhexyl Methoxycinnamate (OMC)-CAS 5466-77-3
Ethylhexyl Methoxycinnamate (OMC) is the most widely used mainstream UVB sunscreen filter in the global cosmetic industry. It can efficiently absorb ultraviolet rays in the 280-320nm UVB band, effectively block ultraviolet radiation that causes skin sunburn, tanning and aging. With stable chemical properties, no peculiar smell and good skin affinity, it is easy to formulate and process with other cosmetic raw materials. As a core cosmetic functional ingredient, it has passed global safety certification and is suitable for mass production of various daily chemical and skin care products, solving the technical demand for efficient and safe sun protection in cosmetic formulas.
Key Benefits
• Efficient UVB Absorption: Precisely absorbs 280-320nm UVB ultraviolet rays, effectively prevents skin sunburn and photoaging, and significantly improves the SPF value of sunscreen products.
• Excellent Formula Compatibility: Good solubility in oil-phase raw materials, compatible with most cosmetic solvents and functional ingredients, no delamination or precipitation in compound formulas.
• Stable Chemical Properties: Low volatility, not easy to decompose under conventional storage and use conditions, long-term stable efficacy, suitable for long-term shelf-life products.
• High Purity & Low Impurity: Industrial high-purity grade (≥99.0%), low harmful residual impurities, meets commercial cosmetic grade production requirements.
• Good Processing Performance: Colorless and odorless, does not affect the color, fragrance and texture of finished products, convenient for industrial batch production.
