The invention relates to novel bleaching and disinfecting agents containing, with regard to the agents: (a) 1.0 to 6.0 wt. % of alkaline metal hypochlorites and/or alkaline-earth metal hypochlorites, (b) 0.1 to 10.0 wt. % of ether carboxylates of formula (I): R[OCH2CH2]u[O(CH2)xCH(R')(CH2)yCH(R'')(CH2)z]v[OCH2CH2]wOCH2COOM, in which R represents a hydrocarbon radical with 6 to 28 hydrocarbon atoms; u and v represent the same or different numbers ranging from 0 to 30, whereby u = 0 if v = 0; w represents a number ranging from 1 to 30, whereby the sum u + v + w </= 30; x, y, z, independent of one another, represent the numbers 0 or 1; R', R'', independent of one another, represent hydrogen, methyl or ethyl, whereby the sum x + y + z > 0 if R' = R'' = H; M represents an alkaline metal or alkaline-earth metal, and containing; (c) 0.5 to 2.0 wt. % of alkaline metal hydroxides and/or alkaline-earth metal hydroxides with the provision that the quantities of constituents (a) to (c) total 100 wt. % with water, optional additional surfactants, auxiliary agents and accessory agents, whereby the weight ratio of the ether carboxylates (b) with regard to these additional surfactants is greater than 3 to 1. The preparations reduce the viscosity and diminish the foaming action of hypochlorite lyes.
