    You should understand water loss that can throw you into net weight noncompliance.

    We produce a lot of cold process soap in our GMP certified facility, and the stability requirements are fairly much the same as for other cosmetic products.

    @Michelle76 As you can find in @PhilGeis‘ link, water loss overtime is critical and needs to be properly assessed in solid soap bars.
