Dodecane
What is Dodecane?
Dodecane is a straight-chain saturated hydrocarbon alkane with 12 carbon atoms (C12H26), sourced from petroleum distillation or synthetic processes. In cosmetics, it functions mainly as a fragrance ingredient, helping to shape the product's scent by masking undesirable base odors and delivering a clean sensory profile. Its low viscosity and high volatility enable quick evaporation on skin, avoiding greasiness while aiding solubility of other fragrance compounds. Occasionally used as an emollient or solvent, it smooths textures and disperses actives evenly in lightweight formulas like perfumes, sprays, and serums. Chemically inert and non-polar, dodecane integrates well into oil-based or anhydrous systems, maintaining stability without reacting under typical storage conditions. Regulatory bodies like the EU CosIng database list it for perfuming and solvent roles in rinse-off and leave-on products.
