standard detergent to determine the colour fastness
This detergent is currently used as a standard detergent to determine the colour fastness of household and commercial laundry and corresponds in composition and washing behaviour to an average phosphate-containing detergent, but does not contain optical brighteners and can be supplemented with a bleaching component by adding sodium perborate.
