ABSTRACT
The stability areas for W/0 microemulsions of decane and water with pentanol as cosurfactant were determined with a/ sodium dodecyl sulphate and b/ a sodium dodecyl sulphate/hexaethylene glycol dodecyl ether combination In a 1/1 weight ratio as surfactants.
The results showed only small differences for the W/0 mlcroemulslon areas with the combined surfactants and with the ionic surfactant alone. It appears that the simple rules for the preparation of W/0 microemulsions stabilized with ionic surfactants also can be used for ionlc/nonionic mixtures of surfactants.
