Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine-CAS 187393-00-6
Cosmetic-grade Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (BEMT) is a high-performance triazine-based full-spectrum organic sunscreen agent, known as the "all-round UV protective shield" in the high-end sunscreen industry. Different from traditional single-band sunscreen filters, BEMT features a unique rigid triazine ring conjugated structure, achieving synchronous and efficient coverage of full UVB (280-320nm) and long-wave UVA (320-380nm) bands, perfectly covering sunburn and photoaging ultraviolet gaps.
With dual absorption peaks at 310nm and 341nm, it delivers balanced and powerful shielding capability for both epidermal sunburn and dermal photoaging damage. The optimized steric hindrance molecular structure endows BEMT with industry-leading ultra-high photostability, requiring no additional photostabilizers.
It maintains stable and consistent UV filtering performance under long-term intense solar radiation without photolysis, attenuation or failure, completely solving the durability pain points of conventional sunscreen products. In addition, the raw material has extremely low molecular migration, excellent thermal stability and high-temperature resistance, no discoloration or efficacy loss during production and storage.
It is mild, non-sensitizing and highly compatible with all mainstream oil-soluble sunscreen agents. BEMT can simultaneously boost SPF and PA values, simplify formula design, and is the core preferred multifunctional raw material for developing high-stability, long-acting, high-power broad-spectrum sunscreen.
Key Benefits
• Dual-Peak Full-Band Absorption: Dual absorption peaks at 310nm and 341nm, synchronously covers complete UVA/UVB spectrum, integrates anti-sunburn and anti-photoaging functions, realizes one-stop full-spectrum protection.
• Ultra-High Intrinsic Photostability: Rigid triazine molecular structure with super anti-photolysis performance, zero efficacy attenuation under long-term sun exposure, no stabilizer compounding required, lasting stable protection.
• Low Migration & High Safety: Optimized macromolecular steric hindrance design, extremely low molecular migration, non-irritating, non-sensitizing, no phototoxicity, compliant with global cosmetic safety standards.
• High Efficiency & Formula Simplification: High molar extinction coefficient with low dosage and high efficiency, simultaneously improves SPF and PA values, reduces total sunscreen dosage and simplifies broad-spectrum formula design.
• Excellent Thermal & Storage Stability: Outstanding high-temperature resistance, no discoloration or deterioration during hot processing and long-term storage, stable performance for mass standardized production.
• Super Formula Compatibility: Perfectly compatible with triazine series, DHHB, DTS and other high-end sunscreen filters, synergistically enhances system stability and outdoor long-lasting waterproof protection.
Applications
