Alkyl polyglycoside (AP) used in a water-based oil dispersant system showed
maximal performance at typical concentrations. Premixtures of AP aqueous s
olutions and fuel oil contributed to higher performance, and therefore its
physicochemical characteristics, such as rheology and conductivity, were st
udied and compared with effectiveness. When an AP containing an electrolyte
(NaCl) is used, effectiveness and stability improve further.
