The present invention relates to compositions containing a polycarbonate including a bisphenol compound and an effective amount of a bishaloformate component present in an amount sufficient to reduce the average unbound bisphenol compound level found in water after immersion in deionized water for two weeks at 40° C. of the composition to less than about 20 ppb. Also provided are methods for increasing the water resistance of a polycarbonate composition. The method involves adding an effective amount of a bishaloformate component to the polycarbonate composition such that the polycarbonate composition has an average unbound bisphenol compound level found in water after immersion in deionized water for two weeks at 40° C. of less than about 20 ppb.
