Safety Information
1-Dodecanol Usage And Synthesis
  • DescriptionLauryl alcohol has a characteristic fatty odor. It is unpleasant at high concentrations but delicate and floral on dilution. It has a fatty, waxy flavor. It may be prepared by hydrogenation of lauric acid; normally employed as a replacement for the corresponding aldehyde.
  • Chemical PropertiesLauryl alcohol has a characteristic fatty odor; unpleasant at high concentrations, but delicate and floral on dilution. It has a fatty, waxy flavor.
  • Chemical Propertieswhite low melting crystalline solid
  • OccurrenceReported found in the oil of Mexican lime and in the oil from flowers of Furcraea gigantean. Also reported found in apple, banana, sour cherry, citrus peel oils, melon, pineapple, potato, thymus, cheeses, butter, milk powder, chicken and beef fat, cooked pork, beer, whiskies, white wine, peanuts, beans, mushrooms, mango, coriander seed and leaf, rice, Bourbon vanilla, endive, crab, clam, Cape gooseberry, pawpaw and maté.
  • UsesUsed as esterification agent.
  • Uses1-Dodecanol is used in chemical formulations for a variety of purposes, including as an emulsion stabilizer, a skin-conditioning emollient, and a viscosity-increasing agent.
  • DefinitionChEBI: A fatty alcohol that is dodecane in which a hydrogen from one of the methyl groups is replaced by a hydroxy group. It is registered for use in apple and pear orchards as a Lepidopteran pheromone/sex attractant, used to disrupt the mating behaviour of certa n moths whose larvae destroy crops.
  • PreparationCommercially prepared by hydrogenation of lauric acid; normally employed as a replacement for the corresponding aldehyde.
  • Aroma threshold valuesDetection: 73 to 820 ppb
  • General DescriptionColorless thick liquid with a sweet odor. Floats on water. Freezing point is 75°F.
  • Reactivity ProfileDodecyl alcohol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
  • Health HazardLiquid will cause burning of the eyes and may irritate skin.
  • Chemical ReactivityReactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
  • Safety ProfileModerately toxic by intraperitoneal route. Mildly toxic by ingestion. A severe human skin irritant. Questionable carcinogen with experimental tumorigenic data. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use dry chemical, CO2. When heated to decomposition it emits acrid smoke and irritating fumes
  • Purification MethodsCrystallise dodecanol from aqueous EtOH, and distil it through a spinning-band column under vacuum. [Ford & Marvel Org Synth 10 62 1930, Beilstein 1 IV 1844.]
