Abstract:
A method comprising washing a colored fabric article in a washing medium comprised of a major amount by weight of water, a first minor amount by weight of a detergent and a second minor amount by weight of an aminosilicone compound having the formula: ##STR32## wherein: R.sup.1 and R.sup.8 are independently selected from the group consisting of hydrogen, hydroxyl, alkyl and alkoxy,R.sup.2, R.sup.3, R.sup.9, and R.sup.10 are independently selected from the group consisting of alkyl, and alkoxy, provided that one of R.sup.2, R.sup.3, R.sup.9, and R.sup.10 may be selected from the group consisting of a primary amino-substituted alkyl group, a secondary amino-substituted alkyl group and an N-(amino-alkyl)-substituted aminoalkyl group having both primary and secondary amine functionality,R.sup.4, R.sup.5, and R.sup.6 are independently selected from the group consisting of alkyl and aryl, R.sup.7 is selected from the group consisting of a primary amino-substituted alkyl group, a secondary amino-substituted alkyl group and an amino-alkyl-substituted alkyl group having both primary and secondary amine functionality, andm and n are numbers wherein m is greater than n and the sum of n and m yield an aminosilicone compound with a viscosity of 10 to 100,000 cps at 25.degree.,wherein said first minor amount by weight is greater than said second minor amount by weight.
