Why do you use Potassium Hydroxide in your Castile Soap?

Potassium Hydroxide is used as the saponifying agent to make the soap. It is what reacts with the oils to turn them from inert oils into foamy soap! This is a chemical reaction that involves water, oil, and potassium hydroxide.

When we make castile soap, we are basically doing alchemy to create a new product from the oils and water. The potassium hydroxide only works for as much as you put in. Through lots of math and testing we know the perfect ratio of each ingredient to add to make soap with no byproduct. 

That is to say, the potassium hydroxide is used up completely and none is left over because it has all reacted to make the soap. 

The same calculation is also done with the water and oils because too much water or oil doesn't make very good soap!

The ingredients list you see is everything that we use to make our Castile Soap. It is all of those ingredients together that make "Castile Soap" as we know it, and even though we add the potassium hydroxide to make the soap, there isn't actually any left in the final product.
