While in the “stress-fill” method, the concentrate is placed inside the container, and possibly the propellant is compelled under pressure with the valve orifice after the valve is sealed, or even the propellant is permitted to movement underneath the valve cap then the valve assembly is sealed (“below-the-cap” filling).
Substances in remedies, on the other hand, tend to be more susceptible to chemical instability in comparison to the good condition and dose for dose, generally have to have additional bulk and excess weight in packaging relative to strong dosage types.
