Abstract: Oil - in - water emulsions were prepared using two gums from the Vulgares series, namely Acacia senegal var. senegal (ASG) and Acacia mellifera (AMF), along with a 1: 1 blend of these gums. Various concentrations of Isopropyl Myristate (IPM) oil were utilized, and the emulsions were monitored for four weeks at 45?C. The morphology of the emulsions revealed dense, spherical droplets. Analysis of particle sizes indicated that AMF gum produced smaller and more resilient droplets compared to ASG. Phase separation was observed at lower oil concentrations for both gum - based emulsions. However, the emulsion containing the blended Vulgares gums (in a 1: 1 ratio), prepared with an optimal oil concentration of 20%, exhibited improved stability.
