Abstract
An improved process for preparing reduced-odor or odorless esters, preferably benzoate esters, octanoate esters, aliphatic emollient esters and glycol dibenzoate esters. The improved process comprises, in part, removing the esterification catalyst from the crude ester after the esterification reaction is substantially complete, before neutralization of acidity. The resultant ester compositions are odorless or have substantially reduced odor as compared to commercially available esters.
