Containers

Definition of Container:

• The containers play a crucial role in maintaining the integrity of the aerosol system.
• The container house 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 Containers Materials

1. Metal Container:

   • Examples: Aluminum, Tin-plated steel, Stainless steel.
   • Advantages: Lightweight, durable, resistant to internal pressure.

2. Glass Container:

   • Advantages: Chemically inert.
   • Limitations: Fragile and less suitable for pressurized systems.

3. Plastic Container:

   • Examples: Polyethylene, Polypropylene.
   • Limitations: Risk of deformation and interaction with the formulation.

Manufacturing Process of Containers:

• Container is 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.
