The direct answer
A component that looks correct can still perform poorly with a specific formula or fragrance. Compatibility must be reviewed for the actual product-pack combination.
Why compatibility matters
Formula or fragrance can interact with bottle, liner, gasket, pump, tube, coating, print or adhesive. Viscosity and particles can also affect dispensing. The relevant risk depends on product type and contact materials.
What to observe
Review leakage, weight change, discoloration, odor change, swelling, cracking, softening, delamination, print resistance, pump output, spray pattern, closure torque and visual appearance under the selected protocol.
Control the approved combination
Record formula version, component supplier and code, decoration, fill level, assembly method and test conditions. A material or supplier change can require renewed review because it creates a different combination.
Frequently asked questions
Does a standard bottle remove the need for review?
No. The actual formula, closure, decoration and assembly still create a specific combination.
Can one test fit every product?
No. The protocol and observation period should reflect the product, pack, risk and destination requirements.
What if a component supplier changes?
Review whether the material and specification are equivalent and determine whether compatibility work must be repeated.
