Alkanes, C13-16-iso- (CAS 68551-20-2) — Citrus Carrier Note Fragrance Ingredient
Alkanes, C13-16-iso-
CAS 68551-20-2
What Is Alkanes, C13-16-iso-?
Alkanes C13-16-iso- are synthetic hydrocarbon mixtures used as solvents and carriers in industrial applications. They’re found in some cleaning products and coatings. These odorless hydrocarbons serve as invisible workhorses, helping other fragrance ingredients spread evenly without contributing their own scent.
Safety Profile
USE WITH AWARENESSWhat Does Alkanes, C13-16-iso- Smell Like?
Alkanes C13-16-iso- are essentially odorless hydrocarbon mixtures. They serve as neutral carriers in fragrance formulations, providing no discernible top, heart, or base notes. Their complete lack of olfactory character makes them ideal for diluting or carrying other aromatic compounds without altering the intended scent profile.
Chemistry, Properties & Perfumer Guide
The Chemistry
Alkanes C13-16-iso- are branched-chain hydrocarbon mixtures synthesized through oligomerization processes. These synthetic alkanes consist of C13 to C16 carbon chains with random branching patterns. They’re produced via catalytic processes from petroleum feedstocks, with the branching improving solubility and lowering viscosity compared to straight-chain alkanes. The mixture lacks functional groups, making it chemically inert.
