Volatile Organic Compound Regulation Accelerating Propellant Conversion
Volatile organic compound regulation continues tightening across major manufacturing jurisdictions, restricting the hydrocarbon propellants that have dominated aerosol filling for decades and pushing manufacturers toward compressed gas, dimethyl ether, and other lower-emission alternatives that require meaningfully different filling equipment specifications. Manufacturers facing these restrictions cannot simply reformulate products without also converting or replacing filling equipment calibrated for a specific propellant chemistry's pressure and flow characteristics. Equipment makers report compressed gas conversion orders now outpacing traditional hydrocarbon equipment orders across nearly every major personal care and household account they serve today. The liquid capsule filling machines market is already worth USD 0.7 billion in 2025, and MMA expects a 6.6% CAGR from here to 2036.
Market Impact: Drives roughly 14% of demand
