Application No. 08/330,597
1. A food grade liquid rinse aid composition,
suitable for dilution to form an aqueous rinse, the
composition consisting essentially of:
(a) about 5 to 50 wt-% of a sorbitan fatty acid
mono ester containing greater than about 15 moles of
alkylene oxide per mole of sorbitan;
(b) about 0.2 to 25 wt-% of a defoamer
