The present invention relates to a low tone photobleaching composition comprising organosilicon (IV) phthalocyanine and naphthalocyanine, having a Q-band absorption maximum at a wavelength of at least 660 nm and having an increased tripolymer yield, thereby increasing the production of singlet oxygen. It is about. The use of Si 4+ phthalocyanine and naphthalocyanine compounds in photobleaching compositions can produce low color wash compositions, bleaching compositions and hard surface cleaners. |
