Abstract
Provided are methods of washing fabric articles in the presence of silicone oils to provide for color protection and/or fragrance retention in the washing of fabric articles with detergents. Fabric articles are washed 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 having the formula: ##STR1## wherein: the variables are defined in the specification wherein said first minor amount by weight is greater than said second minor amount by weight. In preferred embodiments of this method, said washing medium is the product of mixing water with a composition comprised of said aminosilicone compound in association with an insoluble support. In particularly preferred embodiments, an aminosilicone compound wherein R.sup.1 and R.sup.8 are both alkoxy, (typically methoxy) is employed. Provided are powder detergent compositions, without inorganic phosphates, for washing textiles, in particular colored textiles, comprising: PA1 at least one surface-active agent, PA1 at least one inorganic or organic builder which is soluble in the washing liquor, and PA1 at least one aminosilic…
