This assessment focuses solely on the product formula, independent of its packaging. While Stability & Compatibility Testing is recommended for the most accurate results, we understand that packaging timelines can cause delays. In these cases, our lab conducts stability testing using packaging that closely replicates your intended final components, ensuring reliable and representative data. Note: Not required if Stability & Compatibility Testing is selected.
