How is Shelf Life Determined by Stability Testing?

How is Shelf Life Determined by Stability Testing? is a key question in cosmetic and product development. It involves evaluating how long a product maintains its physical, chemical, microbiological, and functional properties under defined conditions.

Types of Stability Testing

• Real-time stability testing (25°C / 60% RH)
• Accelerated stability testing (40°C / 75% RH)
• Stress testing (thermal shock, light exposure)

Parameters Evaluated

• Physical (appearance, viscosity)
• Chemical (pH, active content)
• Microbiological (total count, preservation)

Regulatory Framework

• ISO 22716
• EU Cosmetic Regulation (EC) No 1223/2009
• ICH Q1A(R2)

Conclusion

How is Shelf Life Determined by Stability Testing?
It is determined through scientifically validated stability data, ensuring product safety, performance, and compliance.
