This book is a practical guide for a creative journey of experimentation in the world of handmade natural soap in an ecological and sustainable way. 

It presents the 80 most successful recipes from the Natural Collection workshop and the soap-making seminars of the NGO (Non-Governmental Organization) New Guinea, while also providing all the necessary information to create new recipes that meet your personal needs.

Through its pages, we will discover the history of soap in Europe and the Middle East and approach the different methods of making and using it. We will explain the chemistry of saponification and the differences between natural soap and synthetic detergents. We will describe in detail the cold process of saponification for making solid soap and explain how to deal with any problems that may arise.

Furthermore, we will study the properties of the natural raw materials used in soap making (oils, butters, herbs, essential oils, clays, etc.) and the properties they impart to the resulting soap. Finally, we will explore natural materials that give color, texture, and fragrance to the soap and describe different techniques that make the aesthetic result even more interesting.
