Bentonite

It is a light or cream colored impalpable powder. There are two varieties: Sodium Bentonite; that it has great capacity of sponging in water and Calcium Bentonite; with negligible fluffing property.

It is a natural clay that contains a high portion of Montmorrillonite, a hydrated colloidal aluminum silicate of natural origin, in which some aluminum and silicon atoms may have been replaced by other atoms, such as magnesium, calcium and iron.
