Define the attributes to follow
Stability is more than whether a film still looks acceptable. Depending on the formula, the plan may track active amount, degradation, physical properties, dissolution behavior, microbiology and package integrity. Agree the protocol and acceptance criteria before interpreting the results.
Use the intended pack
The formula, primary sachet, seal and storage conditions must be identified in the study. Changes to ingredients, process, material or pack can affect how earlier evidence applies. Keep the stability configuration and commercial specification linked through change control.
Separate planning from a supported statement
A requested shelf life is a target. A supported shelf-life claim follows appropriate study design and interpretation. Ask the supplier which data exist, what remains in progress, how the product is stored and who approves the final statement for the market.
Questions to put in your brief
- Study formula and revision
- Final sachet configuration
- Conditions and timepoints
- Acceptance criteria
- Change-control implications
Record the answers against the exact formula, packaging configuration and destination market. Mark an item as confirmed only when the applicable evidence or written agreement exists. If an answer is still a target, identify the study, sample evaluation or document review that will resolve it before specification approval.
Turn the discussion into a project
Send the team a non-confidential brief with your ingredient direction, intended market, requested amount per film, flavor, pack count and timing. Ask for a scope that separates development, analytical work, packaging, manufacturing and external charges. Where the concept differs from the published caffeine reference project, confirm its own sample terms, MOQ and timeline.
