Step-by-Step Guide to Resolving Oil-Based Aerosol Instability

Why Are Stability Issues Common in Oil-Based Aerosols?

Oil-based aerosol formulations are prone to separation, viscosity changes, and ingredient degradation due to the nature of oil-based compounds and their interaction with other ingredients and propellants.

Steps to Resolve Stability Issues

Step 1: Adjust Emulsifiers

Incorporate emulsifiers with appropriate hydrophilic-lipophilic balance (HLB) to stabilize oil-water interactions.

Step 2: Optimize Mixing Techniques

Use high-shear mixers or homogenizers during the aerosol production process to achieve uniform blending.

Step 3: Conduct Stability Testing

Test formulations under varying temperature and pressure conditions to identify potential separation or viscosity changes.

Step 4: Improve Packaging

Select aerosol packaging solutions that minimize air ingress and protect against external contaminants.

Conclusion

By optimizing formulations, improving mixing techniques, and conducting rigorous testing, manufacturers can resolve stability issues in oil-based aerosol products and ensure consistent quality.
