Overview
Arkolane Isodiol, chemically known as 2-Methyl-2,4-pentanediol, is a branched-chain diol produced by Arkema with versatile applications across multiple industries. This organic compound serves as an effective solvent and viscosity modifier due to its unique molecular structure that combines two hydroxyl groups with a branched hydrocarbon chain. The material is particularly valued in industrial formulations where a balance between water solubility and organic compatibility is required. Its production follows strict quality control measures to ensure consistency in performance characteristics, making it a reliable component in professional formulations.
Physical and Chemical Properties
Arkolane Isodiol presents as a colorless, slightly viscous liquid with a mild characteristic odor. Its molecular structure featuring both primary and tertiary hydroxyl groups contributes to its distinctive solvent properties and chemical reactivity. The compound demonstrates excellent thermal stability with a flash point of 93°C (closed cup). In terms of chemical behavior, it shows amphiphilic characteristics, dissolving readily in both polar and non-polar media. This property makes it particularly useful as a coupling agent in systems containing both aqueous and organic components. The material's evaporation rate is approximately 0.01 (butyl acetate = 1), providing formulators with controlled drying characteristics.
Main Applications
The primary use of Arkolane Isodiol is in the coatings industry, where it serves as an active solvent for resins including alkyds, epoxies, and acrylics. Its ability to reduce viscosity without compromising film formation makes it valuable in high-performance coating systems. In printing inks, it helps maintain proper flow characteristics and pigment dispersion. Beyond coatings, the chemical finds application in household and industrial cleaning products due to its solvency power and mild odor profile. The cosmetic industry utilizes it in personal care formulations as a humectant and viscosity modifier. Recent developments have explored its potential in agricultural formulations and as a component in hydraulic fluids.
Safety and Storage
While Arkolane Isodiol is classified as low toxicity, proper handling procedures should be followed. The material may cause mild eye and skin irritation upon prolonged contact. Adequate ventilation should be maintained when handling in enclosed spaces, and personal protective equipment including gloves and safety glasses is recommended. Storage should be in approved containers (typically stainless steel or polyethylene) kept tightly closed in a cool, well-ventilated area away from heat sources and oxidizing agents. Bulk storage tanks should be equipped with proper grounding and bonding to prevent static electricity accumulation. The product is stable under normal storage conditions with no significant risk of decomposition.
B2B Procurement Guide
When procuring Arkolane Isodiol, buyers should clearly specify the required grade (technical or cosmetic) and purity level. Typical industrial grades have a minimum purity of 99%, while specialty grades for sensitive applications may require additional purification. Packaging options range from 200kg drums to bulk isotanks for large-volume users. Quality verification should include checks for water content (typically <0.2%) and acid value specifications. Lead times may vary seasonally, so forward planning is advised. Many suppliers offer just-in-time delivery programs for regular customers. For international shipments, ensure compliance with all relevant transportation regulations for glycol ethers.
