CYCLOALIPHATIC AND ALIPHATIC DIAMINE-BASED FATTY ACID DIAMIDES USED AS OGANOGELATORS

摘要

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 C₁₆ 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, said aromatic diamine possibly being partially or totally replaced with 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.
