Abstract: | A synergetic bleaching activation phenomenon of the chlorinated cyclic hindered amine, N-chloro-4-hydroxy-2,2,6,6-tetramethylpiperidine
(TMP-Cl) on sodium perborate (PB) was examined under some practically applicable bleaching procedures. By combining TMP-Cl
with PB, the bleaching effect toward black tea, fruit juices and other stains was enhanced synergetically, achieving an efficiency
similar to that of the well-known tetraacetylethylenediamine/PB system. However, behavior observed in the TMP-Cl/PB system,
such as high bleaching efficiency in an alkaline range, superior durability for repeated bleaching, less discoloration of
cloth that contains reactive dyes and no influence on the activity of an enzyme, was favorable for a bleaching component of
heavy-duty detergents. |
