Dipropylene glycol mono-n-butyl ether 99%+ CAS NO.29911-28-2 Industrial & Cosmetic Grade

Product Features

The product is manufactured via advanced propylene oxide and n-butanol continuous catalytic etherification process, combined with precision distillation and impurity removal technology, with a purity of 99%+ and extremely low content of free alcohol, water and other impurities, ensuring stable and reliable application performance in various formulations; - It has ultra-low volatility and a high boiling point, which greatly reduces solvent volatilization during production and construction, lowers environmental emissions and occupational exposure risks, and is a preferred raw material for green low-VOC chemical formulations; - It exhibits perfect miscibility with water, alcohols, ethers, esters, ketones and hydrocarbons in any proportion, with strong solvency for various resins, polymers, waxes and organic compounds, and wide applicability in both water-based and oil-based systems; - It has an excellent hydrophilic-lipophilic balance, acting as a high-efficiency coupling agent and solubilizer, effectively solving the phase separation problem of multi-component formulations and improving the long-term uniformity and stability of products; - The product features mild chemical properties, low irritation, good thermal and chemical stability, no easy decomposition under normal processing and storage conditions, and meets the safety and environmental standards of industrial and cosmetic grade applications; - Strict full-process quality control is adopted in production, with advanced analytical instruments such as GC (Gas Chromatography) and HPLC for real-time component detection and full analysis, ensuring consistent product quality and compliance with industrial and cosmetic grade application standards. 

Packaging and Transportation

✦  The product is packaged in sealed food-grade HDPE plastic drums or anti-corrosion iron drums with inner coating, with standard packaging specifications of 20kg/barrel, 200kg/barrel and 1000kg/IBC ton barrel to meet the procurement needs of small and large batches; - Customized packaging specifications and materials can be provided according to customer requirements (including cosmetic grade food-grade packaging); - During transportation, the product should be loaded and unloaded gently to prevent package damage and liquid leakage, and transported in accordance with the transportation regulations of general chemical products, avoiding mixing with sharp objects, strong oxidants, strong acids and corrosive goods. 

Safety and Storage

✦The product should be stored in a cool, dry and well-ventilated closed warehouse, away from fire sources, heat sources and direct sunlight, with the recommended storage temperature controlled at 5-35℃; - It should be stored separately from strong oxidants, strong acids, strong alkalis and flammable materials, and mixed storage and transportation are strictly prohibited to avoid chemical reactions and potential safety hazards; - The warehouse should be equipped with corresponding varieties and quantities of fire-fighting equipment (dry powder fire extinguishers, carbon dioxide fire extinguishers, etc.) and complete fire prevention and explosion-proof facilities; - The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials (absorbent cotton, sand, neutralizing agents, etc.), and the leaked liquid should be prevented from flowing into sewers, water sources and other environmental areas; - The product package should be kept sealed during storage to prevent moisture absorption and volatilization, and the shelf life is 18 months under the recommended storage conditions. If the package is opened, it should be used up as soon as possible and resealed tightly to avoid contamination.
