Key points
- Developed an integrated chemical-technological framework for aerosol gas mixtures, combining raw material quality control and multi-parameter product testing.
- APL showed extreme flammability (0.600 propellant fraction, 45.87 kJ/g, 2.1 g/s release, 600–900 mm ignition), ASC showed flammability (0.340 propellant fraction, 26.08 kJ/g, 1.3 g/s release, 150–300 mm ignition), and AHF was not flammable.
- Moisture was identified as a primary cross-cutting risk, leading to corrosion, valve contamination, pressure drop, and instability in aerosol products.
- The framework connects raw material control, filled product analysis, corrosion analysis, and reclaimed solvent verification for comprehensive quality and safety assurance.

Abstract
This study develops an integrated chemical-technological framework for aerosol gas mixtures through combined control of propellant quality, solvent moisture, corrosion risk, and regenerated-solvent suitability. The methodology couples input quality control of gas propellants and organic solvents with multi-parameter testing of filled products (formulation, heat of combustion, vapor pressure at 20 and 50 °C, leak tightness, release rate, ignition distance, and foam ignition). Three products were examined: aerosol penetrating lubricant (APL), aerosol surface cleaner (ASC), and aerosol hair foam (AHF), representing hydrocarbon-rich, solvent–water, and water-dominant systems. Product behavior depended on the balance of propellant fraction, liquid-phase composition, and moisture-sensitive components. APL (highest fraction 0.600; 45.87 kJ/g; 2.1 g/s) ignited at 600–900 mm and was classified as extremely flammable. ASC (0.340; 26.08 kJ/g; 1.3 g/s) ignited only at 150–300 mm, corresponding to a flammable aerosol. AHF was not found to be flammable under the conditions stated above. The pressure, reserve and no leakage were observed in all products. The primary set of cross-cutting risks were moisture, which led to corrosion, contaminating valves, pressure drop, and instability. The method presents a methodology that connects raw material control, filled product analysis, corrosion analysis, and reclaimed solvent verification, and provides a comprehensive pathway to ensure that the aerosol user obtains the desired quality and a safe product.
