Claims8
A composition for removing starch and starch-containing sizing materials comprising an emulsion or dispersion of 10-40% of high temperature aqueous amylase enzyme effective as a desizing agent at about 100.degree. C. or higher, an anionic surfactant present in an amount of 0.5% and a non-ionic surfactant selected from the group consisting of alkyl oxalkylates, alkaryl oxalkylates and fatty acid ethyloxylates present 10-60% with the balance water.
