Sweating M&P soap

by Katrina Wylie

Hello, I have a question regarding melt and pour soap.

We are a little company based in France and we started making all natural soap. The soap base is sls and sles free and we add natural colours and essential oils to it.

The problem we encountering is that the soap is sweating. Sometimes it's really bad and it does not look good at all, even when it is wrapped. We have tried to keep it in different temperatures and it does make a bit of a difference, but selling it to shops we don't have any control over the temperature at which the soap is kept.

Can you suggest anything? Thank you for you help and keep up the good work on your site.

Answer:

M&P soap contains glycerin which is a humectant. Humectants draw moisture from the air and that moisture will settle on the soap.

A couple of things you can do to help to reduce the sweats:

Never put the soap into the fridge or freezer.

Never allow the soap base to boil during the melting process.

Place a fan on the soap once it has been removed from the soap mold.

Use a dehumidifier in your soap room to reduce the excess moisture during the soap making process.

Package the soap as soon as possible after it is hard and dry.

Good luck,
Cathy
