What Is Triple-Milled Soap? | Our Everyday Life
Soap has been around for thousands of years, with a history dating back to 2800 B.C. At its most basic, soap is made of a fat such as shea butter or olive oil and an alkali such as lye. The combination produces a process called saponification, which transforms the mixture into soap. Once the soap hardens, it can then be grated into pearls.
