Chemistry, Properties & Perfumer Guide
The Chemistry
C11-15-Isoalkanes are branched-chain alkanes with 11 to 15 carbon atoms. They are synthesized through the oligomerization of shorter-chain hydrocarbons or by fractionation of petroleum distillates. These compounds are prized for their chemical inertness and lack of odor, making them valuable in fragrance applications where neutrality is required.
