Art and Science of Handmade Soap Making: A Master's Guide To Ingredients, Equipment, And Recipes - Paperback

Soap that has been manufactured the old-fashioned way, by combining oils and fats with an alkali like lye, is considered to be handmade soap.
Natural components like oils and herbs are commonly used in the production of handmade soap. Handmade soap is soft on the skin and can be tailored to the individual needs of the user, in contrast to commercially produced soap, which often contains synthetic components and harsh detergents.
Small quantities of artisanal soap might be sold at boutiques or online. Handmade soap can be manufactured at home with different ingredients and processes.
