Bemotrizinol (Full-Spectrum Triazine Sunscreen Agent)-CAS 187393-00-6
Bemotrizinol (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) is a top-tier high-photostability full-spectrum organic sunscreen raw material in the cosmetic industry. Relying on unique triazine molecular conjugated structure, it has ultra-strong ultraviolet trapping and shielding capabilities, covering the full UVA and UVB wavelength range, making up for the insufficient deep anti-photoaging protection of traditional single sunscreen agents.
Different from ordinary organic sunscreens that are easy to photolyze and fail under strong light, Bemotrizinol has excellent molecular stability, which can maintain long-term and efficient protection under continuous ultraviolet irradiation without efficacy attenuation.
It features low dosage and high efficiency, which can effectively reduce the total addition of sunscreen agents in the formula, optimize product texture, and avoid the heaviness and greasiness of traditional high-dose sunscreen formulas.
In addition, it has outstanding waterproof and sweat resistance and formula synergistic performance, can significantly improve the SPF and PA values of compound sunscreen systems, and is the core upgraded raw material for outdoor high-power, long-lasting and high-stability sunscreen products.
Key Benefits
• Full-Spectrum UV Blocking, Comprehensive Skin Protection: Covers full-band UVA long-wave and UVB medium-wave ultraviolet rays, solves the pain points of incomplete protection of single sunscreen agents. It effectively resists UVB-induced sunburn, redness and peeling, and blocks UVA penetration to improve skin tanning, sagging and photoaging, realizing all-round sunlight damage defense.
• Ultra-High Photostability, Anti-Photolysis & Long-Lasting Efficacy: Unique triazine stable molecular structure, not easy to decompose and fail under long-term strong light irradiation. It avoids the rapid decline of sunscreen efficacy of ordinary organic sunscreens after light exposure, maintains stable high-efficiency protection throughout the day, and greatly improves sunscreen durability.
• Low Dosage & High Efficiency, Optimize Formula Texture: Far higher shielding efficiency than traditional sunscreen raw materials, achieving high SPF/PA multiples with low addition. It reduces the total amount of sunscreen agents in the formula, avoids heavy, sticky and whitening problems of finished products, and creates a light, thin and docile sunscreen texture.
• Excellent Waterproof & Sweat Resistance, Adapt to Outdoor Scenes: It can form a dense and uniform protective film on the skin surface, which is not easy to be washed away by sweat and rainwater. It maintains stable sunscreen effect in high-temperature and high-sweat outdoor environments, solving the problem of easy failure of daily sunscreen products in outdoor scenarios.
• Non-Penetrating & Ultra-Low Irritation, Safe for Sensitive Skin: High-molecular structure, no transdermal penetration, no accumulation in the skin. High-purity refined formula, no harmful impurities, ultra-low irritation, non-sensitizing and mild and safe, suitable for sensitive skin and facial delicate skincare sunscreen formulas.
• Strong Formula Synergy, Improve Comprehensive Performance: Perfectly compatible with physical and chemical sunscreen agents, can synergistically broaden the protection spectrum and exponentially improve sunscreen multiples. It optimizes formula stability, avoids precipitation and delamination, and improves the overall grade and efficacy of sunscreen products.
Applications
• Outdoor High-Power Sunscreen Series: Core high-efficiency raw material for outdoor SPF50+ high-multiplier sunscreen cream, beach waterproof sunscreen, sports sweat-proof sunscreen products. It provides stable and long-lasting full-band UV protection and adapts to harsh outdoor light environments.
• Facial Mild Sunscreen Series: Special low-irritation sunscreen raw material for daily facial sunscreen lotion, isolation sunscreen, sensitive skin mild sun protection products. It balances high protection efficacy and mild skin-friendly performance, no burden on delicate facial skin.
• Long-Lasting Waterproof Sunscreen Products: Key functional raw material for all-day long-acting sunscreen, waterproof and sweat-resistant body sunscreen, summer high-temperature sun protection formulas, which effectively solves the problem of easy failure of sunscreen in sweating and water contact scenarios.
• Anti-Photoaging Skincare Series: Professional UVA deep protection raw material for anti-photoaging essence, anti-aging sunscreen cream, daily anti-light damage skincare products. It blocks long-wave UVA penetration, improves skin sagging and dullness, and delays skin aging.
• Compound High-Multiplier Sunscreen System: Efficacy synergist for compound physical and chemical sunscreen formulas, assisting in broadening protection spectrum, filling protection blind areas, exponentially improving SPF/PA values, and optimizing formula texture stability.
• High-End Daily Sun Protection Products: Widely used in sunscreen primer, makeup base with sunscreen efficacy, body full-body sunscreen lotion and other high-grade daily sun protection products, achieving light texture and high-efficiency dual advantages.
