A strategy has been developed that enables the equilibrium distribution of wool‐grease components and contaminants to be specified in a form suitable for the design of a solvent extraction process. Experimentally determined equilibrium phase compositions for carefully selected model components were fitted by multi‐variable least‐squares regression to an empirical model to provide a convenient mathematical specification. The specification accounts for the dependency of distribution coefficient on concentration and also for the effects of component interactions.
