Not all Herban Lifestyle soaps contain essential oils. Some people’s skin is too sensitive for essential oils, so Ms. Kearns also makes soaps that have no intense smell.
MARY KEARNS: “About half of my soaps have no added essential oils, it’s for people with very sensitive skin who want to avoid essential oils for any reason. And then the other half, I have fun playing with the different scents”
FAITH LAPIDUS: Next, she pours the liquid soap into wooden mold forms. The forms make small rectangular soaps or large bricks of soap. Ms. Kearns puts paper on top of the molds. She lets them sit for a day or two in a warm place so the soap can dry and harden.
Once the soap has reached trace, it is poured into molds to harden and dry out
Later, she takes the soap out of the mold and places it in a storage area to cure or dry for four to six weeks. This curing process permits water to evaporate from the soap. The soap soon becomes firmer which helps it last longer.

STEVE EMBER: Understanding soap-making also requires a short chemistry and history lesson. Soap is made from a chemical reaction called saponification. During saponification, an alkali base such as sodium hydroxide reacts with a fat. This forms a small amount of alcohol called glycerol and a metal salt of fatty acids, or soap. Soap cleans because its molecules attach to nonpolar molecules like oil and polar molecules like water.
