Emulsion Properties of Batyl Alcohol

Abstract

Using a combination of batyl alcohol (BA), isopropyl myristate (IPM), medium chain triglyceride (MCT), and water, an emulsion was developed. A ratio of 1:1 MCT:water was emulsified with 5% and 10% BA. A weak viscoelastic network was formed with 5% BA but without stearic acid (SA) (Emulsion S1). With SA (Emulsion S2) a strong viscoelastic network was formed with the acid acting as a co‐emulsifier. No network structure was found in the emulsion containing 10% BA (Emulsion S4) as it was stabilized by the right percentage of BA. The emulsifiers adsorbed at the MCT/H₂O interface, reducing the droplet size and increasing the viscosity, while the rest formed liquid crystalline lamellar in the continuous phase to physically trap the droplets in the network. The conductivity measured revealed that the oil droplets were encapsulated by the emulsifier in Emulsion S2.
