A foaming pump combines a suitable liquid formula with air as it is dispensed. The pump system needs a compatible consistency to work properly. This collection lists 100 ml and 150 ml bottles, including designs with brush attachments.

The cleanser needs to suit the pump's viscosity requirements. A thick formula can obstruct dispensing or create uneven foam. Use a recipe developed for a foaming dispenser and validate its stability and preservation before packaging it.

Check the filling level, pump assembly and any dried residue near the outlet. Formula thickness or particles can also interrupt flow. Follow the component supplier's maintenance instructions, and review your formulation if the problem recurs during testing.
