Ethyl 2-(4-Diethylamino-2-Hydroxybenzoyl)Benzoate (Long-Wave UVA Special Sunscreen)-CAS 5809-23-4
Ethyl Diethylamino Hydroxybenzoyl Benzoate is a professional long-wave UVA dominant organic sunscreen raw material in the cosmetic industry.
Different from conventional sunscreen agents that focus on UVB protection and have insufficient long-wave UVA shielding, this product has exclusive strong absorption performance for UVA 320–400nm deep band, which is the key raw material to improve the PA value of sunscreen products.
Relying on stable benzoyl molecular conjugated structure, it has excellent photostability, effectively avoiding the problem of efficacy attenuation and secondary light damage caused by photolysis of ordinary organic sunscreens under strong light.
It has low skin irritation and excellent oil solubility, which can be freely compounded with various physical and chemical sunscreen agents to broaden the protection spectrum, fill the deep UVA protection blind area, build a complete full-band UV defense system, and provide long-term and stable deep anti-photoaging protection for the skin.
Key Benefits
• Exclusive Long-Wave UVA Shielding, Fill Protection Blind Area: Targeted absorption of UVA320-400nm long-wave ultraviolet rays that are difficult to block by conventional sunscreens, solve the core pain point of insufficient deep anti-tanning and anti-aging protection of ordinary sunscreen formulas, and greatly improve PA rating.
• Ultra-High Photostability, Long-Lasting Anti-Photolysis: Stable molecular structure, no decomposition and no efficacy attenuation under long-term strong ultraviolet irradiation. It avoids the rapid failure of traditional organic sunscreens, ensures all-day continuous and stable UV protection, and improves outdoor sun protection durability.
• Low Dosage & High Efficiency, Upgrade Full-Spectrum Protection: High molar absorption efficiency, significant UVA shielding effect at low addition. It can compound with UVB sunscreen agents to realize UVA/UVB full-band coverage, easily create high SPF and high PA full-spectrum sunscreen products, and optimize formula cost.
• Mild Low-Irritation, Safe for Sensitive Skin: High-purity refined formula, no harmful residues and sensitizing components. Ultra-low skin irritation, non-transdermal irritation, mild and skin-friendly, suitable for sensitive skin, facial delicate skin and high-safety daily sun protection formulas.
• Excellent Oil-Solubility & Formula Compatibility: Perfectly soluble in various cosmetic oil phases, uniform dissolution without precipitation. Highly compatible with triazine sunscreens, cinnamate sunscreens and physical sunscreen powders, which can significantly improve formula uniformity and system stability.
• Focus on Anti-Photoaging, Improve Skin Resistance: Effectively block deep UVA penetration, inhibit skin collagen damage and oxidative aging, improve skin sagging, dullness and fine lines caused by light damage, and delay skin aging.
Applications
• High PA Full-Spectrum Sunscreen Series: Core UVA boosting raw material for high-PA++++ full-spectrum sunscreen cream and lotion. It makes up for long-wave UVA protection defects, comprehensively improves product sun protection level, and creates professional full-band UV shielding products.
• Anti-Photoaging Skincare & Sunscreen Products: Special deep anti-light-damage raw material for anti-aging sunscreen, daily anti-photoaging skincare lotion and essence. It focuses on solving long-term UVA irradiation skin aging problems and improving skin light resistance.
• Outdoor Long-Lasting Sunscreen Series: Key functional raw material for outdoor high-resistance sunscreen, sports waterproof and sweat-proof sunscreen, and all-day long-acting sun protection formulas. It maintains stable protection under strong light for a long time.
• Mild Sensitive Skin Sunscreen Series: Low-irritation UVA protective agent for facial mild sunscreen, pregnant women’s sunscreen and sensitive skin exclusive sun protection products, balancing high protection and mild safety.
• Compound High-Efficiency Sunscreen System: Professional UVA synergist for physical and chemical compound sunscreen formulas, cooperating with UVB filters to broaden the protection spectrum, fill protection blind areas and exponentially improve sunscreen efficacy.
• High-End Daily Light Protection Products: Widely used in sunscreen primer, isolation cream, body sunscreen lotion and other daily light protection products, realizing light texture, mild formula and high-efficiency anti-tanning and anti-aging effects.
