The invention relates to a fatty diamide comprising or consisting of a reaction product obtained from: (a) at least one cycloaliphatic diamine comprising a ring of 6 carbon atoms, (b) a fatty hydroxy acid chosen from 12-hydroxystearic acid (12-HSA), 9-hydroxystearic acid (9-HSA), 10-hydroxystearic acid (10-HSA), 14-hydroxyeicosanoic acid (14-HEA) or binary or ternary or quaternary mixtures thereof, (c) at least a second diamine chosen from linear aliphatic C2 to C12 primary diamines, (d) optionally, at least one monoacid chosen from saturated and non-hydroxylated linear C6 to C18 carboxylic acids, (e) optionally, at least a third primary diamine different from (c) chosen from linear aliphatic C2 to C12 diamines. (f) at least one aromatic amine chosen from xylylenediamines, the said aromatic diamine possibly being partially or totally replaced with the said diamine (a). The invention also covers the use of this diamide as an organogelling agent, in particular as a rheology additive, for coating, glue, adhesive or cosmetic, stripping, moulding, mastic or sealing compositions.
