FAQ #13 - Why is the weight of my soap different than what's on the label?

One of the biggest challenges natural soap makers face is the weight of the soap bars. 

When our bars have finished their initial cure time they weigh between 5.0 to 5.5 ounces.  However, since water continues to evaporate out of the soap over time it will gradually weigh less. 

Unlike other soap companies, we don't list the weight of our bars at the time they are cut, but rather we use the following formula to calculate what we think the soap will weigh once it reaches our customer:


is defined as the current weight
p is defined as the packaging weight
is defined as the original weight
is defined as the weight loss

The average weight of our soap (several weeks past our cure time) comes out to be 4.8 ounces.  Some customers may receive bars that are slightly more or slightly less than this, so to keep things fair we round down to 4.7 ounces and that is what's printed on our packaging.

If you want to help slow the water evaporation from your soap, we recommend storing your soap bars in a cool and dry area or keep them in a sealed container until your ready to use them.
