Abstract
Six emulsifiers derived from polyisobutylene succinic anhydride (PIBSA) were obtained (E1 to E6) with different Hydrophile-Lipophile Balance (HLBs). Interfacial tension measurements were evaluated for the prepared emulsifiers. The emulsifier (E3 and E6) exhibited the lowest interfacial tension value. Two highly concentrated emulsions (HCE) were prepared. And its stability was scanned form point of HLB, rheology and aging. It was found that, the maximum stability was exhibited by E3 and E6 HLBs, Further the rheological measurement was investigated for (E3 and E6). From the rheological measurement, it was found that, the Bingham yield values (σB) were 1244.4 and 1917.7Pa for the E3, E6 and the Herschel Bulkley values (σH) were 432.66 and 699.66Pa for the E3, E6 respectively. Aging indications the changes in the rheological properties and the aged emulsions fits Cross model. Stability of these emulsions was determined.
