Concentration‐detergency curves were developed for 28 soil‐surfactant systems. These systems consisted of three single component soils and nonionic surfactants from two homologous series. An optimum surfactant concentration was shown to exist for each soil‐surfactant system and was found to be related to the hydrophile‐lipophile balance of the surfactant. From data developed, a relationship is apparent between the hydrophile‐lipophile balance of the soil and the hydrophile‐lipophile balance of the surfactant (of either homologous series) most effective for removing this soil. The relationship points the way for optimization of surfactant type and concentration for a specific soil based upon hydrophile‐lipophile balance calculations.
