The formulation is based upon reducing Interfacial Tension (IFT). The cleaning efficiency of detergents is based upon surface tension (ST) and IFT. ST is largely responsible for foam formation and spreading, which is important for some consumer products. Foaming is undesirable in industrial cleaners and wastewater treatment and IFT (penetration ability) is the critical factor in preliminary assessment.
Although the protein ingredient in FGX3 is not in itself a surfactant some proteins behave similarly and the combination with some surfactants (Protein Surfactant Complexes PSCs) causes a substantial reduction in IFT compared to surfactants alone:
