How to Determine Expiry Dates of Cosmetic Products

Know how long your cosmetic product can remain safe, stable, and fit for use—and how to support that decision with evidence.

Introducing How to Determine Expiry Dates of Cosmetic Products: A Scientific and Regulatory Guide, a practical professional e-book developed by Norio-Olegario Consultants, Inc. (Sunem Consultancy) for those responsible for cosmetic product quality, stability, compliance, and commercialization.

This guide takes you beyond simply assigning an arbitrary “2-year” or “3-year” expiry date. It explains the scientific and regulatory principles behind shelf-life determination, stability testing, Period After Opening (PAO), microbiological stability, packaging compatibility, batch traceability, and cosmetic labeling.

Inside, you’ll find practical guidance on real-time and accelerated stability testing, freeze-thaw and stress studies, preservative efficacy testing, stability specifications and acceptance criteria, shelf-life calculations and worked examples, PAO assessment, product-specific stability considerations, ASEAN/Philippine, EU and U.S. regulatory frameworks, documentation for the Cosmetic Product Information File (PIF), and professionally prepared templates, diagrams, sample problems, computations, and case studies.

Designed for pharmacists, cosmetic science professionals, formulators, QA and regulatory personnel, and cosmetic product brand owners who want to make more scientifically defensible product decisions.

Fully cited with regulatory and technical references.
