Abstract (en)
[origin: EP0881279A2] A solid granulate is claimed which contains (A) 50-40 wt.% cationic, textile-softening agent of formula (I), (II) and/or (III), where R<1> = 1-6C alkyl, alkenyl or hydroxyalkyl; R<2> = 8-28C alkyl or alkenyl; R<3> = as for R<1> or -(CH2)n-T-R<2>; R<4> = as for R<1> or R<2>, or -(CH2)n-T-R<2>; T = -CH2-, -O-CO- or -CO-O-; and n = 0-5; (B) 50-90 wt.% solid carrier comprising an alkali metal-sulphate, -carbonate, -silicate, -citrate or -aluminium silicate or citric acid; and (C) 0-5 wt.% granulating auxiliaries. Also claimed is production of the granulate by low energy impacting of a solid carrier with a cationic surfactant in a mixer, followed by high energy granulation in the presence of water or an aqueous solution of a granulating auxiliary.
