ISO 11930 Preservative Effectiveness Test (PET) – No Suitability

Overview
ISO 11930 preservative effectiveness testing (PET), also known as a preservative challenge test, evaluates the ability of a cosmetic or personal care product to resist microbial contamination over time. This method is widely used to support product safety, stability, and regulatory compliance.

Test Method – ISO 11930
Samples are intentionally inoculated with a panel of challenge microorganisms (typically including bacteria, yeast, and mold). The product is then monitored over a defined time period to assess the reduction and control of microbial populations in accordance with ISO 11930 acceptance criteria.

No Suitability (What This Means)
This service does not include suitability (neutralization) testing, which verifies that the product matrix does not interfere with microbial recovery. It is generally appropriate for:

  • Products with previously validated formulations
  • Low-risk or anhydrous systems
  • Screening or comparative testing

For preserved or complex formulations, suitability testing is typically recommended to ensure accurate and defensible results.

Applications

  • Cosmetic and personal care products
  • Skincare, haircare, and topical formulations
  • Product development and screening
  • Internal quality and stability programs

Key Benefits

  • Evaluation of preservative system performance
  • Supports product safety and microbial stability
  • Alignment with internationally recognized ISO 11930 standard
  • Useful for formulation development and benchmarking
