3 Month Accelerated Stability and Compatibility
The 3 Month Accelerated Stability and Compatibility study provides structured mid-term evaluation of cosmetic and personal care products under controlled 40°C storage conditions. Because extended exposure increases formulation stress, this study offers stronger predictive insight into long-term performance trends.
Throughout the program, analysts evaluate samples at defined timepoints to monitor visual integrity, odor changes, phase behavior, and overall product appearance. In addition, analysts measure pH and weight loss to assess chemical stability and moisture migration over time.
As storage continues, compatibility assessment becomes increasingly important. Therefore, analysts inspect primary packaging for leakage, swelling, deformation, discoloration, and product absorption. These observations help identify gradual packaging interaction risks that may not appear during shorter studies.
A structured mid-study review allows development teams to assess emerging trends before completion. At the end of the program, Pentyl Labs issues a comprehensive final report summarizing all observations and measurements collected during the test period.
Manufacturers frequently use the 3 Month program to support pre-launch validation, retailer documentation requirements, reformulation projects, and packaging updates. Because it provides greater stress exposure than a 1 Month study, this program strengthens shelf life estimation and internal quality review.
Overall, the 3 Month Accelerated Stability study delivers balanced depth and efficiency while supporting informed product development decisions.
