Aerosol Performance

Aerosol cold weather performance, aerosol products from deodorants and paints to automotive lubricants and food whipping creams, are ubiquitous in modern life due to their convenience and precise application. However, while they perform impeccably at room temperature, their functionality—which relies on a delicate balance of propellants, active ingredients, and internal pressure—is profoundly disrupted in cold environments. Common complaints when temperatures drop include weak spray, sputtering, inconsistent particle size, or complete failure. The Science: Why Aerosols Fail in Cold Weather Understanding the physical and chemical challenges aerosols face is crucial for ensuring reliable performance in winter conditions. Pressure Drop and the Ideal Gas Law The pressure inside an aerosol can is […]
