METHODS FOR DISCHARGING COLORANTS

摘要

The present invention describes a method of neutralizing an organic colorant or stain. The method enables a user to discharge a discoloration caused by staining with a substance having at least a molecular structure containing either a macrocyclic or linear hematin or linear unsaturated carbon chains or a cyclic aromatic chromophore in a rapid and effective manner. The method, in part involves, treating the discoloration with a medium containing unsaturated fatty acids or esters thereof, and a surfactant or a cell- lysing agent in amounts expressed as a ratio ranging from about 1 :5, up to about 30:1, respectively. The color of said stain is reduced by a ?E value of 5 or greater.
