Diethylamino Hydroxybenzoyl Hexyl Benzoate-CAS 302776-68-7
Cosmetic-grade Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a high-end oil-soluble organic long-wave UVA filter, known as the "gold standard" of high-stability UVA protection in the sunscreen industry. Different from conventional UVA absorbers with poor stability and easy photolysis, DHHB adopts a highly stable conjugated molecular structure, which focuses on efficiently absorbing long-wave UVA (320-400nm), especially solving the protection gap of deep UVA (340-380nm) that causes skin tanning, sagging and photoaging.
It has ultra-high molar extinction coefficient, with strong and concentrated UVA absorption capacity, which can efficiently block deep ultraviolet rays that penetrate the dermis, fundamentally improve the PA protection index of formulas, and achieve true full-band UVA defense.
The product has leading photostability, no molecular decomposition or efficacy attenuation under long-term continuous sunlight irradiation, no phototoxicity and no sensitization, perfectly solving the failure problem of traditional UVA sunscreen agents after sun exposure.
With mild and non-irritating properties, excellent thermal stability, and no discoloration or deterioration under high temperature environment, it can be perfectly compounded with various UVB filters to form a complete UVA/UVB broad-spectrum sunscreen system. It is the core preferred raw material for developing high-PA, long-acting, anti-photoaging high-end professional sunscreen products.
Key Benefits
• Super Long-Wave UVA Full-Band Interception: Targeted absorption of 320-400nm full UVA band, make up for deep UVA protection gap, effectively improve PA value, inhibit skin tanning and photoaging, and realize comprehensive dermal UV protection.
• Top-Level Photostability & Zero Photolysis: Ultra-stable molecular structure, resistant to ultraviolet photodegradation, no efficacy attenuation after long-term sun exposure, lasting stable UVA protection, no sunscreen failure.
• High Efficiency & Low Dosage: Ultra-high molar extinction coefficient, strong absorption efficiency, small addition amount can significantly improve full-spectrum protection performance, reduce total sunscreen dosage and formula burden.
• Mild Non-Sensitizing & High Safety: No phototoxicity, no irritation, low sensitization, safe for sensitive skin and long-term daily use, compliant with global cosmetic sunscreen regulations.
• Excellent Compatibility & Broad-Spectrum Synergy: Perfectly compatible with all mainstream UVB filters, oil-phase solvents and emulsifier systems, synergistically build UVA/UVB full-band broad-spectrum sunscreen, stable formula system.
• High Thermal Stability & Easy Storage: Resistant to high temperature discoloration and oxidation, stable performance in high-temperature production and summer storage, not easy to deteriorate, suitable for mass commercial production.
