ndodecanol

n-Dodecanol, also known as 1-dodecanol or lauryl alcohol, is a straight-chain fatty alcohol with the formula C12H26O. It is a colorless to white waxy solid or a high-boiling liquid at room temperature, depending on grade and impurities. It consists of a twelve-carbon aliphatic chain terminated by a primary hydroxyl group, giving both lipophilic and hydrophilic character.

Production and origin: It is produced mainly by hydrogenation of fatty acid derivatives derived from natural fats and oils (notably lauric acid from coconut and palm kernel oils) or by chemical synthesis from linear alkenes via hydroformylation followed by hydrogenation.

Properties: It is sparingly soluble in water and soluble in many organic solvents such as hexane, diethyl ether, and alcohols. It has a relatively high boiling point and is relatively stable under normal storage conditions.

Applications: In industry, n-dodecanol serves as a fatty alcohol feedstock for the manufacture of surfactants, including detergents and emulsifiers, and as a precursor to esters used in fragrances and flavors. It is also used as an intermediate in the synthesis of lubricants, plasticizers, and specialty coatings. In cosmetics, it is used as an emollient and thickener in some formulations.

Safety: n-Dodecanol is flammable and can cause skin and eye irritation on contact. It should be handled with appropriate personal protective equipment and used in well-ventilated areas. It is typically evaluated under applicable chemical safety regulations to determine any occupational exposure limits or labeling requirements.
