Abstract
Colloid-chemical properties, such as interfacial tension, adsorption, the area occupied by a molecule, adhesion and interfacial activity of a new biodegradable Peg-free emulsifier – polyglyceryl-3 methylglucose distearate and nonionic surfactant – ethoxylated izononilfenol at the water / vaseline oil interfaces were investigated. By varying a hydrophilic-lipophilic balance of emulsifiers an optimal ratio of microemulsion systems was found. The phase diagram of Water / Ethoxylated Izononilfenol : Polyglyceryl-3 Methylglucose Distearate / Vaseline Oil was constructed and the fields of various supramolecular structures were characterized. The sizes of the microemulsion droplets and the structure of the liquid crystal phase were identified.

Keywords: lyotropic liquid crystals, microemulsions, polyglyceryl-3 methylglucose distearate, pseudo-ternary phase diagram, phase transition
