This document specifies a method for the determination of foamability and degree of foamability of surface active agents by means of a circulation equipment, whereby the solution of the surface active agent is under fast circulation.The method is applicable to many surface active agents, especially for low and medium foaming surface active agents and products containing surface active agents.
