The Rehbinder effect in physics is the reduction in the hardness and ductility of a material, particularly metals, by a surfactant film.[1]

A proposed explanation for this effect is the disruption of surface oxide films, and the reduction of surface energy by surfactants.[2][3]

The effect is of particular importance in machining, as lubricants reduce cutting forces.[3][4]
