and Summary Interfacial tension data are presented for cotton‐seed oil‐water and paraffin oil‐water systems containing purified sucrose palmitates of different degrees of acylation. Both the monopalmitates and diplamitates effectively reduced interfacial tension. To be effective, the monoesters had to be dissolved in water, the diesters in oil. Although nearly inactive alone, sucrose tripalmitate was active in mixtures with the mono‐and dipalmitates. Efficiencies of the sucrose palmitates were also excellent. In general, mixtures of sucrose palmitates were as effective as the most active component. When dissolved in water, the efficiency of sucrose palmitate mixtures was proportional to the monoester content, but when dissolved in oil mono‐, di‐, and triesters contributed to the efficiency.
