Low hue photobleaching compositions comprising organosilicon (IV) phthalocyanine and naphthalocyanines of formula I and II respectively, 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 Si4+ phthalocyanine and naphthalocyanines compounds in photobleaching compositions allows for formulation of low hue laundry compositions, bleach compositions, and hard surface cleaners |
