High Purity Dipropylene Glycol DPG 99.5% CAS 25265-71-8 for Cosmetic Fragrance & Industrial Solvent

Dipropylene Glycol (abbreviation DPG, CAS:25265-71-8, molecular formula C₆H₁₄O₃) is colorless transparent viscous aliphatic dihydric alcohol synthesized via propylene oxide hydration and precise continuous rectification separation. Our products are divided into cosmetic grade and industrial grade according to purification standard, featuring low volatility, excellent hygroscopicity, outstanding mutual solubility with water, alcohol, ether and most organic solvents, moderate surface activity and stable chemical property under normal temperature. Cosmetic grade DPG goes through deep deodorization and impurity removal to control ultralow aldehyde, moisture and heavy metal content, complying with USP, FCC and international cosmetic raw material standard; industrial grade is cost-effective with stable indexes for coating, resin and industrial cleaning formulation. With dual hydroxyl functional groups on molecular chain, DPG works as multi-functional solvent, humectant, antifreeze and reaction intermediate, widely used in daily cosmetics, essence spices, paint coating, fine chemical synthesis and tobacco industry globally.

Applications
**Cosmetic & Personal Care Industry (Core High-end Application)**:
Premium humectant and solubilizer for shampoo, body wash, facial lotion, essence, cream and makeup products. It efficiently dissolve essential oil and lipophilic essence components, avoid raw material layering in cosmetic formula; meanwhile replenish skin moisture to improve product moisturizing effect and reduce dry skin irritation. Approved for skincare and oral care raw material by international cosmetic safety specification.
**Fragrance & Flavor Processing Industry**:
Universal solubilizer and carrier solvent for synthetic essence, fruit flavor and spice oil. It helps insoluble aromatic ingredients disperse evenly in water-based beverage and daily fragrance system, stabilize aroma volatilization speed and extend fragrance retention time, widely applied in food essence, perfume and air freshener production.
**Coating, Ink & Water-based Adhesive Field**:
High-boiling coalescing agent and slow-dry solvent for water-borne paint, printing ink and environmental composite adhesive. It reduces film-forming temperature of latex paint, promote complete resin film formation without cracking or pinhole, adjust construction fluidity of ink and improve finished product gloss and adhesion performance.
**Fine Chemical & Chemical Intermediate Synthesis**:
Important starting raw material for production of polyester resin, plasticizer, surfactant and polyurethane auxiliary; used as reaction solvent in organic synthesis to control reaction rate and improve finished intermediate yield.
**Tobacco, Antifreeze & Industrial Cleaning**:
Tobacco humectant to retain cut tobacco moisture, prevent dry broken cigarette and stabilize smoke taste; formulated into low-temperature antifreeze liquid for air-conditioning and industrial equipment; also serve as solvent for heavy-duty industrial detergent and metal cleaning agent.

Product Advantages
✅ Two optional grades: cosmetic grade with ultra-low impurity meets EU cosmetic import requirement; industrial grade realizes cost advantage for large-batch coating raw material procurement.
✅ Low odor and stable boiling range, not easy to volatilize during high-temperature processing, effectively avoid finished product peculiar smell.
✅ Excellent compatibility with water and various polar/nonpolar raw materials, wide matching range for different downstream formulas.
✅ Strict batch laboratory inspection before delivery, COA, MSDS and relevant qualification certificates supplied for global customs clearance.
✅ Sufficient factory spot stock, support small drum trial order and IBC tank / flexitank bulk long-term delivery.

Packaging & Storage
Standard packing: 210kg sealed HDPE iron drum; 1000kg IBC tank and flexitank available for bulk shipment. Store inside cool, dry, shaded and ventilated ordinary chemical warehouse, keep containers tightly sealed, stay away from open flame, high temperature heat source, strong oxidants and strong acid to prevent chemical reaction and raw material deterioration. Avoid long-term direct sunlight exposure. Valid shelf life: 24 months under standard sealed storage.

Safety Information
Low-toxicity alcohol chemical, non-dangerous goods for sea, land and air conventional transportation. Long-time repeated skin contact may cause slight dryness; wear rubber gloves and goggles during filling and sampling. Once liquid splashes into eyes, flush continuously with plenty of running clean water. Complete MSDS including leakage disposal and first-aid guidance is attached with every shipment cargo.
