In the rapidly evolving global cosmetic and personal care landscape, sun protection technology has shifted decisively toward broad-spectrum protection, long-term photostability, and stringent toxicological safety. Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB, CAS 302776-68-7) stands as a cornerstone organochemical UV filter, specifically engineered to provide maximum defense against Long-wave Ultraviolet A (UVA-I and UVA-II, range 320–400 nm).
Historically, formulation chemical engineers relied heavily on legacy UVA absorbers such as Avobenzone (Butyl Methoxydibenzoylmethane). However, Avobenzone suffers from severe photo-degradation upon exposure to sunlight, losing up to 50–70% of its protective efficacy within an hour unless paired with costly photo-stabilizers. DHHB overcomes this fundamental limitation through an intrinsic intramolecular hydrogen bond structure, enabling it to absorb UV energy and harmlessly dissipate it as thermal vibration without breaking down.
DHHB exhibits outstanding light resistance. Exposure to intense solar radiation triggers zero meaningful chemical degradation, ensuring consistent UVA & PA rating performance over extended periods.
Readily soluble in synthetic esters like Isopropyl Myristate (IPM), C12-15 Alkyl Benzoate, and polar oils. Easily incorporated into the oil phase of O/W or W/O emulsions without recrystallization risks.
Compliant with EU Cosmetics Regulation (EC) No 1223/2009 up to 10% concentration. Free from eco-toxic concerns associated with legacy halogenated or coral-bleaching filters.
As a leading China manufacturer, JIMPOCHEM maintains rigorous batch-to-batch quality metrics verified through High-Performance Liquid Chromatography (HPLC) and Gas Chromatography-Mass Spectrometry (GC-MS).

The global market demand for high-performance UV absorbers is experiencing exponential growth, driven by heightened consumer awareness regarding photo-aging, skin hyperpigmentation, and skin oncology. Procurement directors across North America, Europe, Asia-Pacific, and South America are actively restructuring their raw material supply chains to transition from older UV filters to modern photostable molecules.
Regulatory bodies worldwide—including the European Chemicals Agency (ECHA) and ASEAN Cosmetics Committee—are tightening restrictions on chemical filters linked to endocrine disruption or marine toxicity (such as Benzophenone-3/Oxybenzone and Octinoxate). DHHB represents an environmentally benign, highly tolerated alternative that meets the strict "Ocean-Safe" and "Reef-Safe" criteria adopted by premium global beauty brands.
Modern cosmetic consumers expect sunscreens to deliver light texture, zero white cast, and seamless compatibility with active anti-aging ingredients (such as Ascorbyl Glucoside and Azelaic Acid). DHHB's superior oil solubility facilitates non-greasy, elegant cosmetic formulations suitable for daily wear under makeup.
Beyond personal care, industrial procurement managers utilize DHHB in high-end clear coatings, automotive polishes, optical films, and specialty plastics. Its high molar extinction coefficient at 354 nm effectively shields sensitive polymeric matrices against UV-induced yellowing, embrittlement, and mechanical degradation under outdoor exposure.
China's fine chemical manufacturing sector has undergone a profound transformation toward continuous automated processing, intelligent supply chain digital integration, and stringent zero-emission environmental compliance.
At JIMPOCHEM CO., LTD, our 500+ acre industrial chemical production complex in Jinan City, Shandong Province utilizes Distributed Control Systems (DCS) to govern every chemical transformation stage. From catalyst metering and temperature feedback loops during the esterification and condensation reactions to continuous crystallization and vacuum drying, human error is minimized, ensuring exceptional purity profiles.
Achieving high Sun Protection Factor (SPF) and high Protection Grade of UVA (PA++++ ratings) requires precise formulation synergy. DHHB operates primarily in the UVA band peak (354 nm), making it the ideal formulation partner for broad-spectrum UVB absorbers.
Combined with oil-soluble emollient esters such as Isopropyl Myristate (IPM), DHHB yields featherlight skin-feel fluids. Adding hydrating agents like Sodium L-Pyroglutamate locks in skin moisture during solar exposure.
Formulated in water-in-oil (W/O) emulsions, DHHB exhibits outstanding wash-off resistance when combined with structural film-formers and specialized emulsifiers like Dioctyl Sulfosuccinate Sodium Salt.
Protects transparent polycarbonate, polyurethane automotive clear coats, and optical lenses from yellowing. Often paired with fluorinated solvents such as Ethyl Nonafluorobutyl Ether (HFE-7200) for specialty liquid coating preparations.
To achieve high SPF (SPF 50+) and broad-spectrum protection (UVA Critical Wavelength > 370 nm), chemical engineers pair DHHB with supplementary UV filters:

While both chemicals absorb UVA radiation, Avobenzone is highly photo-unstable and degrades under sunlight unless paired with chemical stabilizers. DHHB (Diethylamino Hydroxybenzoyl Hexyl Benzoate) features an intrinsic intramolecular structure that makes it inherently photostable. It does not degrade under prolonged sunlight exposure, eliminating the need for photostabilizers and ensuring consistent long-term UVA protection.
Under European Union Cosmetics Regulation (EC) No 1223/2009 (Annex VI), DHHB is approved as a safe UV filter at concentrations up to 10.0% in ready-for-use cosmetic preparations. Similar regulatory limits (up to 10%) are accepted across China (NMPA), Japan (MHLW), South Korea (MFDS), and ASEAN jurisdictions.
DHHB is oil-soluble and should be dissolved in the oil phase during the heating stage (typically at 60°C–70°C). High-efficiency solvents for DHHB include C12-15 Alkyl Benzoate, Dibutyl Adipate, Isopropyl Myristate (IPM), and Dicaprylyl Carbonate. Pre-dissolving DHHB in ester oils ensures a uniform crystalline-free emulsion.
Yes. JIMPOCHEM’s DHHB is fully REACH-registered for the European Union market. Furthermore, DHHB exhibits no bio-accumulation hazards in aquatic environments and is free from oxybenzone/octinoxate, rendering it compliant with "Hawaii Reef-Safe" and global clean beauty standard protocols.
JIMPOCHEM supplies DHHB in standard 25 kg fiber drums lined with double PE anti-static bags, or customized 500 kg bulk super-sacks. The material should be stored in cool, dry, well-ventilated conditions away from direct sunlight and oxidizers. Under sealed storage conditions, DHHB retains a guaranteed shelf life of 24 months.
Absolutely. Our R&D team provides complete application support—including SPF/PA in-silico simulation, solubility mapping, viscosity tuning, and pilot stability testing—to assist our global B2B clients in accelerating product time-to-market.
