Carrier emulsions in dyebaths are stabilized by adding a compound of formula I or II in which R is a saturated or unsaturated fatty (at least 8 carbon atoms) compound contain. ing one or more reactive hydrogen atoms (as defined) M is an alkali metal ion,- Mg<SP>++</SP>, Ca<SP>++</SP>, NH 4 <SP>+</SP> or an amine salt, X is 2-31 Z is 1-3 and a and b are each 2-4, or by adding a compound of formula Ia or IIa in which R and Z are as above, M is an alkali metal ion, NH 4 <SP>+</SP>, or an amine salt, X is 1-30, m, p, q and r are each 1-3 but the sum of (n+p) and the sum of (q+r) must not exceed 4.
