Tutorial: Correcting Propellant-Pressure Issues in Aerosols

What Is Propellant-Pressure Balance?

The propellant-pressure balance ensures that the internal pressure of the aerosol canister remains consistent for effective spray performance. Errors in this balance can lead to spray inefficiencies or product failure.

Common Causes of Errors

• Overfilling: Excessive aerosol propellants increase internal pressure beyond safe levels.
• Underfilling: Insufficient propellant results in weak sprays.
• Valve Issues: Faulty aerosol valve technology disrupts pressure regulation.

Steps to Fix Pressure Imbalances

Follow these steps to address pressure issues:

• Recalibrate aerosol filling machines to ensure accurate measurements.
• Inspect valves and seals for wear and tear.
• Test the pressure levels in every batch during aerosol
