The container plays a crucial role in maintaining the integrity of the aerosol system.
The container houses both the formulation and the propellant under pressure.
The choice of container material depends on the nature of the product, the propellant, and the intended use.
Types of Container Materials
Metal Containers:
Examples: Aluminum, Tin-plated steel, Stainless steel.
Advantages: Lightweight, durable, resistant to internal pressure.
Glass Containers:
Advantages: Chemically inert.
Limitations: Fragile and less suitable for pressurized systems.
Plastic Containers:
Examples: Polyethylene, Polypropylene.
Limitations: Risk of deformation and interaction with the formulation.
Manufacturing Process:
Containers are usually manufactured with precision to ensure uniform wall thickness and a consistent capacity. Surface treatments may be applied to enhance compatibility and stability.
Considerations:
Pressure resistance.
Compatibility with the formulation.
Prevention of leakage or contamination.
