Detergents represent the largest industrial application of enzymes amounting to 25-30% of total sales of the enzyme. The enzymes used in detergents must be cost effective, safe to use and be able to perform the task in the presence of anionic and non-ionic detergents, soaps, oxidants etc, at pH between 8-10.5%. The chief enzymes used are proteases, alpha -amylase and sometimes cellulase.
