Preservative Efficacy Testing (PET) is a critical process in the development and quality control of pharmaceutical, cosmetic, and food products. It involves evaluating the effectiveness of preservatives in preventing microbial growth and contamination.

1. Ensure Product Safety: Verify that the preservative system is effective against a range of microorganisms.
2. Meet Regulatory Requirements: Comply with regulatory standards and guidelines for preservative efficacy.

1. Microbial Challenge Testing: Inoculating the product with a known quantity of microorganisms.
2. Preservative Effectiveness Evaluation: Measuring the reduction in microbial growth over time.
3. Criteria for Acceptance: Establishing criteria for preservative efficacy, such as log reduction in microbial counts.

1. Product Stability: Ensuring the product remains safe and effective throughout its shelf life.
2. Regulatory Compliance: Meeting regulatory requirements for preservative efficacy.
3. Consumer Safety: Protecting consumers from potential microbial contamination.

1. Pharmaceuticals: Ensuring the safety and efficacy of pharmaceutical products.
2. Cosmetics: Verifying the preservative effectiveness in cosmetic products.
3. Food: Evaluating the efficacy of preservatives in food products.
