Overview
2-Tetradecanol, also known as tetradecan-2-ol, is a secondary fatty alcohol with a 14-carbon chain. It is widely used in industrial and cosmetic applications due to its emulsifying and moisturizing properties. The compound is typically derived from natural sources like coconut or palm oil, though synthetic production is also common. In the chemical industry, 2-tetradecanol serves as an intermediate for surfactants, lubricants, and other specialty chemicals. Its biocompatibility and mildness make it a popular ingredient in personal care products such as lotions, creams, and hair conditioners.
Physical and Chemical Properties
2-Tetradecanol is a white to off-white solid or waxy flakes at room temperature. It has a melting point of 38-42°C and a boiling point of approximately 290°C. The compound is insoluble in water but readily dissolves in organic solvents like ethanol, ether, and chloroform. Its molecular structure includes a hydroxyl group at the second carbon, which contributes to its surfactant properties. The density of 2-tetradecanol is around 0.82 g/cm³ at 20°C, and it exhibits low volatility under standard conditions.
Main Applications
2-Tetradecanol is primarily used in the production of surfactants, which are essential in detergents, emulsifiers, and wetting agents. Its ability to reduce surface tension makes it valuable in industrial lubricants and metalworking fluids. In the cosmetics industry, 2-tetradecanol acts as an emollient and thickener in skincare products. It is also used in pharmaceuticals as a solubilizing agent for poorly water-soluble drugs. Additionally, it serves as a precursor for esters and other derivatives in specialty chemical synthesis.
Safety and Storage
While 2-tetradecanol is generally considered low in toxicity, proper handling precautions are necessary. Avoid inhalation of dust or vapors and minimize skin contact by wearing gloves and protective clothing. In case of contact, rinse thoroughly with water. Store the compound in a cool, dry, well-ventilated area away from heat sources and open flames. Keep containers tightly sealed to prevent contamination and moisture absorption. Dispose of waste material in accordance with local regulations.
B2B Procurement Guide
When procuring 2-tetradecanol, verify the CAS number (1653-30-1) and purity specifications to ensure product quality. Reputable suppliers should provide certificates of analysis (CoA) and material safety data sheets (MSDS). Consider purchasing in bulk for cost savings, as prices typically range from $50 to $100 per kg. Evaluate supplier reliability, lead times, and logistical support. For cosmetic or pharmaceutical use, ensure the product meets relevant regulatory standards such as USP or FCC grades.
