Overview
Ethylhexanediol, also known as 1,3-Ethylhexanediol, is a diol compound with a wide range of industrial applications. It is primarily used as a humectant in cosmetics and personal care products, where it helps retain moisture. The compound is also utilized as a solvent in various industrial processes and as an active ingredient in insect repellents. Its chemical stability and low volatility make it a preferred choice in formulations requiring prolonged shelf life. Ethylhexanediol is synthesized through the catalytic hydrogenation of ethyl acetoacetate, a process that ensures high purity and consistent quality.
Physical and Chemical Properties
Ethylhexanediol is a colorless to pale yellow liquid with a mild odor. It has a molecular weight of 146.23 g/mol and a density of 0.942 g/cm³. The compound is soluble in water and most organic solvents, making it versatile for various formulations. Its melting point is -40°C, and it boils at 243°C, indicating stability under a wide range of temperatures. The low volatility of ethylhexanediol contributes to its effectiveness in applications requiring long-term performance, such as cosmetics and industrial coatings.
Main Applications
In the cosmetics industry, ethylhexanediol is valued for its humectant properties, which help maintain skin hydration in lotions and creams. It is also used as a solvent in nail polish removers and other personal care products. Industrially, ethylhexanediol serves as a solvent for resins, dyes, and inks. Its ability to dissolve a wide range of substances makes it useful in manufacturing processes. Additionally, it is an effective ingredient in insect repellents, where it enhances the efficacy of active compounds.
Safety and Storage
Ethylhexanediol should be handled with care to avoid skin and eye contact. Protective equipment such as gloves and goggles is recommended during use. In case of contact, rinse immediately with plenty of water. Storage conditions should include a cool, dry, and well-ventilated area, away from heat sources and open flames. Properly sealed containers are essential to prevent contamination and degradation. The compound is stable under normal conditions but should be kept away from strong oxidizers.
B2B Procurement Guide
When procuring ethylhexanediol, buyers should prioritize suppliers with certifications such as ISO or GMP to ensure product quality. Purity specifications should be clearly stated in purchase agreements, typically ranging from 98% to 99.5%. Bulk purchasing can reduce costs, with prices commonly ranging from $5 to $10 per kilogram. Buyers should also consider logistics, as the compound is classified as a hazardous material in some regions, requiring special transportation handling.
