The aqueous phase behavior of poly(oxyethylene) alkyl ethers (CmEOn) having both ultra-long hydrophobic and hydrophilic chains (m =30 and n =94 and 42) was investigated. The HLB values of C30EO94 and C30EO42 are 18 and 16, respectively. In C30EO94 system, micellar solution phase (Wm), micellar cubic (I1), hexagonal (H1) and solid surfactant phases (S) are successively formed. The same sequence is observed for C30EO42 system, but the I1 phase shrinks and the H1 phase prevails over a wide range of composition. This phase sequence was compared to that of conventional poly(oxyethylene) surfactants and it was found that the surfactant layer curvature of aggregates becomes less positive in a long hydrocarbon-chain surfactant system even if the HLB values are the same.
