The short answer
Evaluate spray performance using the intended formula, pump and bottle assembly. Define the desired delivery, pattern, actuation and user experience before approving the system.
A pump can look suitable on a bottle without producing the spray experience expected by the brand. Formula properties, the selected pump and the assembly configuration all need to be considered together.
Turn preferences into criteria
Describe the intended use rather than requesting a vague premium mist. Ask the pump specialist which measurements and comparisons are appropriate. Use consistent conditions when comparing candidate pumps.
Assess performance over use
Include priming, repeated actuation, leakage checks and behaviour as the pack empties in the agreed evaluation. Record the exact components and formula used so results are not incorrectly applied to a different assembly.
Procurement checklist
- Confirm the formula and pump reference.
- Define the desired spray experience.
- Use consistent comparison conditions.
- Evaluate priming and repeated use.
- Document the approved assembly and results.
Common question
Can spray performance be judged from the bottle shape?
No. Shape affects the overall pack, but spray function must be evaluated with the pump, formula and complete assembly.
