Various hand wash samples were formulated using a novel polymer based on sorbitol, polyethylene glycol, citric acid has been synthesized. A combination of maleic, and citric acid has been used for esterification. The experimental conditions, order of addition of ingredients, ratio of ingredients, catalyst, time and temperature have been standardized to get desired molecular weight, HLB ratio and viscosity characteristics. Spectroscopic studies of I.R. and N.M.R. of polymers have been undertaken which reveal presence of ester, ether, free Hydroxyl and free acid groups in the polymer. The selected polymer has been used as replacement of conventional linear alkylbenzenesulphonate in liquid detergent formulations. The compositions are ecofriendly and economical as they depend upon vegetable source polymers. Biodegradation study of novel polymers was studied. The hand wash samples were prepared by using prepared polymers. The antimicrobial activity of hand wash samples for certain bacteria such as, E. coli, S. aureus and were studied.
