How do I use Sensitive Hand Wash?

To use Sensitive Hand Wash, wet your hands with water, apply one pump to your palm, and lather by massaging over your palms, between your fingers, and around your nails and cuticles. Rinse well with water and pat dry. One pump dispenses 2ml. At a kitchen and bathroom sink, a 1.5L bag typically lasts around three months.

One pump is all you need. The formula works without a heavy lather.

1

Wet your hands with water.

2

Press the pump once to dispense a small amount onto your palm.

3

Lather by massaging over your palms, between your fingers, and around your nails and cuticles.

4

Rinse well with water and pat dry.

At a kitchen and one bathroom sink, a 1.5L box typically lasts around three months.


How do I fill the pump bottle from the bag-in-box?

To fill the Hand Wash Pump from the bag-in-box, unscrew and remove the pump head. Line up the black piece on the tap with the flat sides of the opening, then twist slowly until you feel a soft, gentle resistance. That is the open position. Do not twist past it. The flow is surprisingly fast at full open and very hard to control. A partial open gives you much more control. Hold the bottle steady, check the fill level from the side as you go since the bottle is opaque, and stop well before the shoulder of the bottle. Close by twisting back to resistance, replace the pump head, twist to unlock, and prime with a few presses.

The tap is a twist mechanism with a fast flow. Don't rush it the first time. The bottle is opaque so check the level from the side as you fill.

1

Unscrew and remove the pump head from the bottle.

2

Line up the black piece on the tap with the flat sides of the opening. Twist slowly until you feel a soft, gentle resistance. That is the open position. Don't stop there. There is no loud click, it is a tactile stop. Twist past it.

3

Hold the bottle steady underneath and open the tap partially rather than all the way. The flow is fast at full open and easy to overshoot. Check the fill level from the side as you go since the bottle is opaque. Stop well before the shoulder of the bottle.

4

Twist the tap back to close, screw the pump head on, twist to unlock, and press a few times to prime before use.
