Abstract
There is disclosed an aqueous formulation comprising PA0 (a) a bleach stabilizing component, PA0 (b) a salt of an organic carboxylic acid and PA0 (c) a preservative. The novel formulation is suitable for use as bleaching liquor for cellulosic fiber materials and is distinguished by a superior stabilizing action, a very good capacity for binding heavy metal ions, a good inhibition of crystallization, and the treated fiber materials have very good rewettability. A significant advantage of the novel formulation is its good biodegradability.
