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 cellulas
es 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.
The Syrian detergent companies used to add high percentage of perborate
salt in laundry detergents formulation to achieve best bleaching and cleaning
results. And usually the bleach activator which transforms the peroxides into
more effective mate
rials, was added to the formulation in non specified doses.
The studies have been made of the effect of the bleach activator -TAED on
the perborates salt show the possibility to reduce the amount of the used
perborates by controlling the - Perborates / TAED percentage in the detergent
formulation .
The released active oxygen depends on the ambiant temperature where
weak activity where detected when temperature exceeds ٦٠ celsius. This study
shows the role of the detergent formulation on the bleach activator where it
releases the active oxygen in a higher percentage when monohydrate sodium
perborate is used, and no effects were detected on the tensile strength of the
used fabric.
