(Also known as: dodecyl alcohol; lauryl alcohol; duodecyl alcohol; alcohol C12; Codling moth pheromone component) |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

1-dodecanol does not exhibit isomerism in its pure form. However, dodecanol as a broader category can include positional isomers like 2-dodecanol or 3-dodecanol, where the hydroxyl group is attached to different carbon atoms along the chain, but these are not isomers of 1-dodecanol itself. |

1-dodecanol can be obtained from palm oil or coconut oil fatty acids and methyl esters by hydrogenation. It may also be produced synthetically via the Ziegler process |
|
There is no publicly available GHG emissions data specifically for the production of 1-dodecanol. However, based on similar long-chain fatty alcohols and petrochemical intermediates, estimated emissions would be in the range 5–15 kg CO₂e per kg of 1-dodecanol |
