USEFUL WHITENING COMPOSITION FOR THE BRINGING OF STAINED ARTICLES WHICH UNDERSTAND UREIA CLATRATE OF A PEROXIDE COMPOUND

摘要

A bleaching composition useful for the bleaching of stained articles, comprises (a) a urea clathrate of a diacyl or tetraacyl peroxide, e.g. dinonanoyl peroxide, dioctanoyl peroxide or diperoxyazelaic diacetate. The composition may also comprise (b) a compound capable of yielding hydrogen peroxide in an aqueous medium, e.g sodium perbonate. The composition, which can be effective against carotenoid stains, is generally in granular form and may be formulated as a laundry detergent composition that also comprises (c) an anionic, nonionic, cationic, ampholytic or zwitterionic detersive surfactant and, optionally, (d) a detergent builder and/or (e) a bleach activator.
