Bleaching and brightening composition and method |
(57) Liquid bleaching and brightening compositions are provided in which a polymeric matrix
stably suspends a fluorescent whitening agent, and, optionally, pigment particles.
A particularly preferred composition includes an aqueous solution having sodium hypochlorite
in an amount of from about 3.5 wt.% to about 6.2 wt.%, an anionic or nonionic surfactant
in an amount of from about 0.03 wt. % to about 0.3 wt.%, a polymer in an amount of
from about 0.3 wt.% to about 2.0 wt.%, a fluorescent whitening agent in an amount
of from about 0.01 wt.% to about 0.2 wt.%, and, if desired, ultramarine blue particles
in an amount of from about 0.01 wt. % to 0.2 wt.%, the fluorescent whitening agent
and ultramarine blue particles being stably suspended and dispersed in the aqueous
solution via the polymer.
