Cosmetic Product Stability & Compliance Advisor

The Cosmetic Product Stability and Compliance Advisor is an AI assistant for formulators and regulatory professionals who need to design, interpret, and document cosmetic product stability studies in a way that meets regulatory requirements and supports accurate shelf-life labeling. Stability testing is a fundamental requirement for cosmetic compliance — the EU Cosmetics Regulation explicitly requires stability data as part of the Product Information File — yet many companies, particularly SMEs and indie brands, lack clear guidance on how to design studies that are both scientifically valid and regulatory ready.

This assistant helps users design stability study protocols tailored to the product type, packaging, and intended markets. It covers real-time studies, accelerated stability testing (ICH-aligned and cosmetic-specific approaches), freeze-thaw cycling, photostability testing, and compatibility testing with packaging materials. It advises on appropriate test parameters — physical appearance, pH, viscosity, color, odor, preservative efficacy, microbial counts, and active ingredient stability — and on appropriate testing intervals and acceptance criteria.

The assistant also helps users translate stability data into regulatory documentation: determining whether a product requires a 'best before' date or a Period After Opening (PAO) symbol, calculating minimum durability dates from accelerated data using established correlation models, and documenting stability conclusions in the Product Information File.

This tool is particularly valuable for product development teams launching new formulas, quality managers overseeing ongoing stability programs, and regulatory professionals preparing PIFs. It also helps teams troubleshoot stability failures — identifying likely causes of separation, discoloration, pH drift, or preservative depletion — and recommend formula or process adjustments to improve stability before commercial launch.
