1-Dodecanol

1-Dodecanol, also known as lauryl alcohol, is a fatty alcohol with the chemical formula C₁₂H₂₆O. It is a colorless, water-insoluble solid with a floral odor. 1-Dodecanol is used in the manufacture of surfactants, lubricants, and emollients.

Structure and Properties

1-Dodecanol is a linear saturated fatty alcohol with a 12-carbon chain. Its molecular weight is 186.34 g/mol. It has a melting point of 24 °C and a boiling point of 259 °C. The compound is insoluble in water but soluble in organic solvents such as ethanol and diethyl ether.

Production

1-Dodecanol is typically produced by the hydrogenation of lauric acid, which is derived from coconut oil or palm kernel oil. The process involves the reduction of the carboxylic acid group to an alcohol group.

Applications

1-Dodecanol is widely used in the production of detergents and cosmetics. It acts as a surfactant and emulsifier, helping to stabilize mixtures of oil and water. In cosmetic formulations, it is used as an emollient to soften and smooth the skin.

In the industrial sector, 1-Dodecanol is used as a lubricant and as an intermediate in the synthesis of other chemicals. It is also used in the production of plasticizers and pharmaceuticals.

Safety and Environmental Impact

1-Dodecanol is considered to be of low toxicity. It can cause mild skin and eye irritation upon contact. In the environment, it is biodegradable and does not persist in the ecosystem.
