Abstract

The phase behavior of binary systems composed of water and nonionic surfactants were investigated. The nonionic surfactants studied were the methoxypolyoxyethylene dodecanoates (R11COO(EO) n CH3,n=4.9, 6.1, 7.3, 9.3, and 12.8, wheren is the average number of oxyethylene units).

The phase behaviors of R11COO(EO) n CH3 were compared with those of the polyoxyethylene dodecyl ethers (R12O(EO) p H) and polyoxyethylene methyl dodecyl ethers (R12O(EO) q CH3) which have been previously reported. It was found that the R11COO(EO) n CH3s have lower cloud points and lower upper limit temperatures for the existence of the mesophase as compared to the other two types. A R11COO(EO)12.8CH3/water system had favorable solution properties for practical use, such as a relatively narrow hexagonal liquid crystalline region and a lower melting point than the ordinary alcohol ethoxylate type nonionics.
