Effects and properties of poly(sodium α‐hydroxyacrylate) (PHA) on removal of stearic and oleic acids from cellulosic filter paper under various wash conditions were evaluated and compared with those of sodium dodecyl sulfate (SDS) by using differential scanning calorimetry. PHA had a much greater effect on the removal of stearic and oleic acids than SDS under the same washing conditions. PHA produces complexes with fatty acids on filter paper during the washing process, and in DSC these complexes have endothermic peaks at temperatures higher than the melting point of the fatty acids. The complexes are formed at temperatures both below and above the melting point of the fatty acid and are removed completely from filter paper by rinsing. The conditions of temperature, time, and PHA concentration during washing all affected the formation of the complex and the removal of fatty acid. Whether the fatty acid chain was saturated or not did not affect the formation of a complex.
