Syria consumes as many as ١٢٨ thousand tons of detergents yearly. The powder detergent with added enzyme represents is about ٣٥ % of the total production .The enzyme content in the detergent is ٠,٥-١,٠ %. Amylases, Lipases, Proteases, and cellulases are the main enzymes used in detergents. Enzymes are known to have protein structure and play role in biocatalysts during the cleaning process. Enzyme activity is affected by heat and the detergent s components such as oxidants, bleachers, and brighters. This research was focused on using Volgemyta method, which traditionally used for saliva and blood analyses to determent the Amylase activity in detergents produced in Syria. The result in dicate that this setteed may be used to determent the commercial Amylase activity in water, and in ٠,١ % Sodium chloride water solution, and finally in physiological solutions . The effect of the different detergents on the Amylase activity has been studied as well. As a result, the addition of any extra amount of Amylase makes no increase or improvement in the cleaning performance of the detergent.
