About
A lightweight branched-chain hydrocarbon that acts as an emollient, creating a smooth, non-greasy skin feel while forming a subtle occlusive barrier.
Pentyldodecane is a branched aliphatic hydrocarbon conforming to the general formula C17H36. It is produced through petrochemical synthesis and finds use in cosmetic formulations as an emollient and skin conditioning agent. Its branched structure gives it a lower viscosity than straight-chain alkanes, providing a light, smooth feel without greasiness. Like other hydrocarbons of similar chain length, it is not absorbed into skin, remains on the surface, and is considered inert.
Skin benefits
- Occlusive barrier formation
- Smooth emollient feel
- Non-comedogenic (non-pore-clogging)
Known concerns
- Essentially inert on skin; no significant concerns reported
