A formulation having reduced gel formation tendencies comprising:
- at least one gel forming alkoxylated surfactant;
- an agrochemically active ingredient;
- and
- a gel prevention surfactant,
- said gel prevention surfactant comprising at least one alkyl amidoamine derivative represented by the formula (7):
- where R is a linear or branched, saturated or unsaturated alkyl group having 2-22 carbon atoms and each of W, Y and Z are (poly)ethyleneoxy groups.
A method for reducing the gel formation tendency of a formulation which comprises at least one gel forming alkoxylated surfactant and an agrochemically active ingredient, said method comprising the incorporation, in said formulation, of at least one gel prevention surfactant, said gel prevention surfactant comprising at least one alkyl amidoamine derivative of formula (7).
