Some disperse dyestuff which include two sulphonate groups in their structures were esterifed by different molar ratios of lauroyl chloride to produce some laureate ester. Surface properties before and esterification were meaured, PC20, Imax, Amin pCMC and DG?m for the esterifed compounds were also evaluated. The results obtained show promising applicbility for these esterified compounds as surface active agents
