The invention concerns novel formulations containing at least one quaternized aminoalkylsiloxane and at least one compound selected among: a) non-ionic hydrophilic surfactant compounds, b) hydrophilic dispersants and c) divalent of trivalent metal salts with inorganic acids. Said formulations are excellent textile softeners for finishing textile structures in accordance with continuous or drawing process and are characterized by particular shearing stability.
