A Brief (yet Fascinating) Explanation of Soap Crystals!

Soap is a crystal that foams. Who knew?

All soap is a crystal. Here’s how it works: Acidic and bases are reactive with their environment. In soap acidic oils have extra electrons to share and alkali bases are very needy for electrons. When they hook up they form stable structures that are neither acids or bases. Something new is formed – a soap crystal. Done right no measurable free alkali remains in the final soap product. Large crystals form large short lived bubbles that have a harshness that is felt on sensitive skin. Small crystals make a thick, mild, long lasting lather that takes time to build. The art of the soapmaker is in fact to to create mid-sized crystals of uniform size resulting in copious lather AND a super mild product.
