Why sabonete clean?

The soap (or sabonete) is made with some soluble ingredients in water and othersin oil. The soluble part in oil acts first, unfastening the dirt of the skin (that she is oily), thus the debris is untied, ready so that to another part of the soap it suspends them, so that the water carregue them even so. The foam that if form is resulted of the action of the water, air and of the body, and appears through the friction. To little foam of some sabonetes can be caused by the high mineral level in the water or by being kept in place where they are not wet frequently, amongst other reasons.
