Why is my Sensitive Hand Wash thinner than expected?Updated 6 hours ago

TL;DR: Sensitive Hand Wash can thin a little in cold storage, and it's temporary. Move the bag-in-box somewhere at room temperature, leave it a few hours, then give it a gentle shake before you fill the pump bottle. It doesn't change how well the wash cleans.

Why is my Sensitive Hand Wash thinner than expected?

The texture of Koh Sensitive Hand Wash responds to temperature, so cold storage can thin it temporarily. A cool pantry, a garage, or a delivery that has travelled in winter will all do it. Bring the bag-in-box to room temperature and give it a gentle shake and the consistency comes back. It does not change how well the wash cleans.

The texture responds to temperature. A cool pantry, a garage, or a delivery that has travelled through a cold week can all thin it for a while.

It isn't a fault and it isn't watered down. The formula is the same one that left the factory, and it cleans the same way. Bring it back to room temperature and the texture comes back with it.

How do I get the consistency back?

Move the bag-in-box out of the cold to a spot at normal room temperature, leave it for a few hours, then give it a gentle shake before filling the pump bottle. Store the box somewhere dry and indoors rather than in a garage or an unheated laundry, and the texture stays steady from one fill to the next.

Four steps, then you're done

1

Move the bag-in-box out of the cold to a spot at normal room temperature.

2

Leave it a few hours. There's no need to warm it deliberately, and don't put it near a heater or in hot water.

3

Give the box a gentle shake before you fill the pump bottle.

4

Store the box somewhere dry and indoors from then on. A bathroom cabinet or under the sink beats a garage or an unheated laundry.


Can texture vary between boxes?

Small differences in texture between boxes of Koh Sensitive Hand Wash can happen, because raw ingredient sourcing shifts a little between batches. It does not change how well the wash cleans. If a box still seems unusual after a few hours at room temperature, get in touch with the Koh team and we will take a look.
