Liquid, aqueous washing or cleaning product formulation, comprising d) at least one washing- or cleaning-active enzyme; e) 1,2-propylene glycol; f) nonionic surfactant of the general formula R1-CH(OH)CH2O-(AO)w-(A'O)x- (A"O)y-(A"'O)z-R2, in which R1 is a straight-chain or branched, saturated or mono- or polyunsaturated C6-24-alkyl or -alkenyl radical; R2 is a linear or branched hydrocarbon radical having from 2 to 26 carbon atoms; A, A', A" and A"' are each independently a radical from the group of -CH2CH2, -CH2CH2-CH2, -CH2-CH(CH3), -CH2-CH2-CH2-CH2, -CH2-CH(CH3)-CH2-, -CH2-CH(CH2-CH3), w, x, y and z are each values between 0.5 and 120, where x, y and/or z may also be 0, are notable for a good phase and enzyme stability and good cleaning performance. |
