Phase diagrams of ternary systems consisting of polyoxyethylene nonylphenyl ether (NP-<I>n</I>) which has the different degree of polymerization of ethylene oxide, <I>n</I>, nonylphenol (NP-0) and water were studied. The phase diagrams of ternary NP-10NP-0H<SUB>2</SUB>O systems resembled to those of binary NP-<I>n</I>H<SUB>2</SUB>O systems, in which n equals to the calculated average degree of polymerization of ethylene oxide in the mixture of NP-10 and NP-0. In the case of 25 ≥ <I>n</I> ≥ 15, the ternary systems showed phase diagrams a little different to that of binary systems, since the region III which contained the unsolubilized NP-0 phase appeared and enlarged its area rapidly with increasing concentration of NP-0, but they exhibited unusual zone owing to the discontinuity of cloud point (CP) curve which resulted from the enlargement of the dispersed system region R<SUB>TP1</SUB>. In the ternary system of <I>n</I> ≤ 30, of which binary aqueous system exhibited at least one hardening or dispersed system region, the region of hardening or dispersed system changed with the increasing concentration of NP-0 according to the following order : R<SUB>HP3</SUB> → R<SUB>TP2</SUB> (R<SUB>HP2</SUB>) → R<SUB>TP1</SUB>. Ternary system containing NP-50, which exhibited no hardening region in the binary system, exhibited neither region R<SUB>HP3</SUB> nor region R<SUB>TP2</SUB> (R<SUB>HP2</SUB>), but the region R<SUB>TP1</SUB> together with the heterogeneous region I above CP curve appeared initially and then the region III appeared and increased so rapidly that the region R<SUB>TP1</SUB> contracted with increasing concentration of NP-0 and therefore there was found no unusual zone. In the ternary system of PEG 2000, which contained no lipophilic group in the molecule, the dispersed system and hardening region could not be found, but only the region III appeared.
