(57) Abstract: Organosilicon (IV) phthalocyanines and naphthalocyanines with Q band absorption maxima at 660 nm and increased triplet state yields, thereby increasing the production of singlet oxygen, And a low hue photobleaching composition. The use of Si 4+ phthalocyanine and naphthalocyanine compounds in photobleaching compositions allows for the formulation of low hue laundry compositions, bleaching compositions, and hard surface cleaners. |
