Ordering and branding
Compatibility testing
Also written as stability testing, formula packaging compatibility.
Filling the actual container with the actual formula and leaving it, at temperature, to see what happens.
What it needs from a bottle
The step that catches panelling, discolouration, closure weep and gasket swell before ten thousand units of it. Ordering ten units of each candidate exists so this is cheap.
Formats that suit it
- Acids
- Solvents
- Essential oils
Order from a single bottle, so a first run can be a test rather than a bet on a guess.
