The subject of this work is the influence of sodium bentonite along with the surfactants in ecological detergent, in view of its qualities of absorbency and fabric softening. Bentonite is a clay composed of different minerals, containing hydrated aluminium silicates and belonging to the montmorillonite family (smectite clays with a layered structure). The surfactants used were an anionic surfactant, namely sodium dodecylbenzenesulfonate (SDBS), and the non-ionic surfactants, namely alkyl polyglucoside (APG), separately and in mixtures of the anionic and non-ionic surfactants in different proportions, in order to determine their influence on detergency, with a constant concentration of bentonite in the formulations in two different particle sizes. The softness of the washed cotton fabric was evaluated to ascertain the effectiveness of the bentonite as a softener, by means of a subjective touch test. Likewise, the possible loss of whiteness by the fabric due to absorption of the bentonite was evaluated
