Zusammenfassung:A GRANULAR FABRIC SOFTENING COMPOSITION, WHICH CAN BE ADDED TO WATER TO FORM AN AQUEOUS CONCENTRATED EMULSION, COMPRISING NONIONIC FABRIC SOFTENER, PREFERABLY A FATTY ALKYL ESTER A POLYHYDRIC ALCOHOL, AND A MONO-LONG-CHAIN ALKYL CATIONIC SURFACTANT. IN PARTICULAR, THE USE A SORBITAN ESTER WITH A MONO-LONG-CHAIN ALKYL CATIONIC SURFACTANT PROVIDES A GRANULAR SOFTENING AGENT CAN BE USED TO FORM A HIGHLY DISPERSED, CONCENTRATED, AQUEOUS COMPOSITION WHICH, WHEN ADDED TO, E.G., A RINSE CYCLE OF A TYPICAL WASHING PROCESS, EFFECTIVELY DEPOSITS ONTO FABRIC FROM THE AQUEOUS BATH. THE PARTICLE SIZE (DIAMETER) OF THE GRANULES SHOULD BE BETWEEN ABOUT 50 AND ABOUT 1000 MICRONS, PREFERABLY BETWEEN ABOUT 50 AND ABOUT 400 MICRONS.THE GRANULES PREFERABLY CONSIST ESSENTIALLY OF AT LEAST ABOUT 25% OF THE NONIONIC FABRIC SOFTENER AND AT LEAST ABOUT 5% OF THE MONO-LONG-CHAIN ALKYL CATIONIC SURFACTANT.
