Abstract (en)
[origin: US4751023A] A novel aqueous composition comprising (a) a mixture of monomeric and oligomeric compounds of the formula <IMAGE> (1) wherein Y1 is hydrogen or -CO-T1, R1, X1 and T1 are each independently C1-C4alkyl and m1 is an integer from 1 to 17, (b) a polyhydroxy compound, (c) an alkali metal silicate, (d) an alkali metal hydroxide, (e) a magnesium salt and (f) an alkali metal salt of an alkyldisulfonic, aryldisulfonic or alkaryldisulfonic acid. The composition is storage stable and is particularly suitable for use as bleaching activator and bleaching stabilizer for the pretreatment of cellulosic fibre materials with a bleaching liquor that contains a per compound.
