Cosurfactant has a very important role in microemulsified systems and it is largely responsible for their stability, mainly in systems formed by ionic surfactants. In this work ethyl and isoamyl alcohols were used as cosurfactants in microemulsified systems to evaluate their influence in obtaining anionic surfactant-based gels. Steady and oscillatory shear experiments were carried out to study and compare rheological properties of specific systems. From the obtained results one can observe that ethyl and isoamyl alcohols influence gel structure and this can be verified through rheological analysis. |
