Association behavior of polyoxyethylene (20) cetyl ether (brij 58) and polyoxyethylene (20) sorbitan monooleate (Tween 80) with polyoxyethylene (4) lauryl ether (Brij 30)
The association behaviour of Brij 58-H2O and Tween 80-H2O with a third component consisting of Brij 30 was investigated. The results were presented in the form of ternary phase equilibriums of H2O - Brij 30 - Brij 58 system and H2O - Brij 30 - Tween 80 systems. The liquid crystalline phase is determ...

| 总结: | The association behaviour of Brij 58-H2O and Tween 80-H2O with a third component consisting of Brij 30 was investigated. The results were presented in the form of ternary phase equilibriums of H2O - Brij 30 - Brij 58 system and H2O - Brij 30 - Tween 80 systems. The liquid crystalline phase is determined by visual observation of the birefringence under the crossed polarized light. The results showed that the solubilisation for the mixture of Brij 30-Brij 58 and Brij 30-Tween 80 were favourable. The associated formation of self- assembled structures like micelles and lyotropic liquid crystalline were observed. The result showed that the presence of Brij 58 promotes formation of lamellar liquid crystal compared to the Tween 80 counterpart. |
