TLDR
BleBleach composition comprising one or more bleaching agents and polyoxometallates of the formula: (Q)q(A a X x M m O y Z z(H2O)b).cndot.Abstract:
Bleach composition comprising one or more bleaching agents and one or more polyoxometallates of the formula: (Q)q(A a X x M m O y Z z(H2O)b).cndot.cH2O as bleaching catalyst, the symbols Q, A, X, M, Z, q, a, x, m, y, z, b and c being as defined in the description. These polyoxometallates increase the bleaching activity, especially at lower washing temperatures.read more
