Batyl alcohol (BA) is widely used in cosmestic products, but little is known about its phase behaviour and rheological properties in ternary systems. Phase diagram of BA/Isopropyl Myristate (IPM)/H20 was constructed at 80 degree celcius and its rheological properties and phase behaviour were studied. Ternary system of BA/IPM/H20 exhibited a viscoelastic network in the rheology test. Lamellar and hexagonal liquid crystal were also found in 90/10 and 100/0 mixtures of BA and IPM, respectively. They were identified by their patterns of Maltese crosses and fan structures, respectively. A focal conic fan-like pseudo-isotropic texture were also found in the system. Addition of either medium chain triglyceride (MCT) or propylene glycol (PG) to the system resulted in disappearance of viscoelastic network.
