Common Name(s): Propane,propane,hydrocarbon aerosol propellant,spray dispensing gas
CAS Number: N/a
DESCRIPTION
What It Does: Generates the vapour pressure required for aerosol dispensing — the propellant expands on valve opening providing the driving force that atomises the formulation into fine spray droplets for even, controlled application.
Why It's Used: Propellant selection determines aerosol performance characteristics: spray pattern, droplet size, particle distribution, and environmental profile. the propellant balance sets container pressure throughout the product's use life for consistent spray from full to near-empty.
How It Works: Propellant liquefies under pressure inside the container — vapour pressure (~4-10 bar) provides the driving force for spray dispensing. hydrocarbon propellants: vapour pressure from van der waals attraction in liquid phase; hfcs: vapour pressure from f-atom electronic effects on boiling point; co₂/n₂: dissolved compressed gas providing pressure from henry's law equilibrium.
