Shelf Life Prediction & Accelerated Testing Protocol
Design accelerated shelf life tests and predict product stability scientifically
What You Can Do
You can design and execute accelerated shelf life testing (ASLT) protocols that scientifically predict how long your products remain safe and effective. Claude helps you select optimal testing conditions, analyze degradation kinetics using the Arrhenius equation, interpret microbiological and physicochemical data, and document findings in formats required by FDA, EFSA, and other regulatory bodies. This ensures your shelf life claims are defensible, compliant, and grounded in real data rather than conservative estimates.
Features
Select temperature, humidity, and light conditions; create sampling timelines; determine testing intervals for zero-order and first-order kinetics
Calculate activation energy and extrapolate real-time stability from accelerated data with confidence intervals
Distinguish chemical, microbiological, and physical degradation; identify critical quality attributes and acceptance criteria
Format stability reports for FDA, EFSA, ICH, and national authority submission requirements
Apply statistical models to stability datasets; assess degradation trends and shelf life endpoints with sensitivity analysis
Evaluate barrier properties, migration potential, and storage condition impacts on shelf life
Identify high-risk degradation pathways and adjust testing strategy to capture worst-case scenarios

You can submit marketing copy, label claims, or advertising language and receive a structured compliance assessment that maps claims against FDA/FTC guidance, state regulations, and case law. The skill identifies claim type (health claim, structure-function claim, comparative claim, etc.), flags regulatory risks across jurisdictions, assesses substantiation strength, and recommends revisions to reduce enforcement exposure. This accelerates claim review workflows and prevents costly post-launch violations.
