Low hue photobleaching compositions comprising organotin (IV), organogermanium (IV), organopaltinum (IV), organopalladium (IV), organolead (IV) or organophosphorous (III) phthalocyanine and napthalocyanines having Q-band absorption maxima at wavelengths greater than 660 nm and increased triplet state yields whereby production of singlet oxygen is increased. Use of Sn 4+ , Ge 4+ , Pt 4+ , Pd 4+ , Pb 4+ , P 3+ pthalocyanine and naphthalocyanines compounds in photobleaching compositions allows for formulation of low hue laundry compositions, bleach compositions, and hard surface cleaners. |
