US Classification:

510466

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.

US Classification:

252 99

Abstract:

The invention concerns detergent compositions comprising a special type of oxidation resistant nonionic surfactant and an oxidizing agent which may either be a hypochlorite or a peroxygen material. The surfactant component structurally comprises a C. sub. 8 -C. sub. 12 alkyl substituted phenoxy hydrophobe alkoxylated with ethylene oxide and/or propylene oxide, with the proviso that the ratio of ethylene oxide to propylene oxide is at least 1 but no higher than 10. Methyl or chloroethyl groups are used to endcap the surfactant.
