Will Sensitive Hand Wash work with my existing dispenser?Updated 6 days ago
TL;DR: Sensitive Hand Wash pours straight from the 1.5 L refill box into most standard pump and squeeze dispensers. No dilution needed. Koh also makes a dedicated Hand Wash Pump bottle built for this formula, holding 350 ml and dispensing 2 ml per press.
Will Sensitive Hand Wash work with my existing dispenser?
✓ Standard pump and squeeze dispensers
Pour Sensitive Hand Wash from the refill box straight into a standard pump or squeeze dispenser and it is ready to use. No dilution. The viscosity suits most common dispenser types as it comes from the 1.5 L bag-in-box.
⚠ One exception: foaming dispensers
A foaming head needs a thin, watery liquid to aerate. Sensitive Hand Wash is a richer formula, so it will not dispense properly through a foaming mechanism. Use a press-to-dispense pump instead.
How do I fill my own dispenser from the refill box?
The same routine works for a Koh pump or your own bottle.
Open the tap on the 1.5 L bag-in-box. Sit the box on the edge of a bench so the tap clears the surface.
Hold the dispenser steady and fill to just below the neck. Leaving a little headroom stops product pushing out when you refit the head.
Unlock the head if it has a twist collar. Koh pumps arrive locked so they do not leak in transit. Twist the collar beneath the nozzle to release it.
Press several full pumps until product flows. Any newly filled bottle needs priming before the first proper dose.
