The wetting power of aqueous solutions of mixtures of an ethoxylated fatty alcohol (AE) and an alkylpolyglucoside (AG) and (concentration ratios expressed in dry weight AE:AG = 1:0, 4:1, 3:1, 2:1, 1:2, 0:1) has been evaluated. At low concentrations, the mixtures show better wettability than the pure surfactants. The wettability of mixtures of these surfactants is not significantly influenced by the water hardness or citric acid concentration. Together with the chemical nature of these surfactants, these properties make them especially interesting for the formulation of biodegradable detergents or wetting agents.
