Soap is a product obtained through the reaction of a base on a fat. Its classical usages at home level are washing and body hygiene. It is a product which can be manufactured as well at home and family levels as at semi-industry and industry levels.

The chemical process (saponification) of soap making is easy. Nevertheless the technological process to be adapted towards obtaining a good quality product is somewhat difficult (complex).

In fact the achievement of a good finish product requires the mastery of some basic knowledge concerning the choice and treatment of raw materials, as well as the correct execution of the saponification.

The adoption of a good procedure in carrying soap making operations at home level could allow from local raw materials, on-site production of a soap with practical acceptable qualities.

In the following lines, we would try to lay the foundations towards achievement of such a process for improved soap making at home level.

In this purpose, we will communicate the simple process of soap making as well as the basic techniques for conditioning of a finish soap; in particular the nature, the main proprieties and the simple techniques of pre-treatment of raw-materials are exposed.
