Embodiment 1

[0061] The following compositions were prepared by mixing in deionized water (percentages are percent by total weight):

[0062] components

Embodiment 2

[0064] 36 pieces of polyester, nylon / lycra and viscose fabrics were cut into 25x25cm pieces. The fabric was washed in a washing machine at 50°C with detergent. In the rinse cycle, half of the fabric was treated with FC#1 and the other half with FC#2. The fabric is dried in an electronic tumble dryer.

[0065] 1.6 grams of artificial perspiration and 1.6 grams of sebum deposits (composition given in Tables 1 and 2) were sprayed on each fabric and the fabrics were lined to dry for 30 minutes. The fabric was washed again in the washing machine and the fabric treated with FC#1 was treated with FC#1 and the fabric treated with FC#2 was treated with FC#2 in the rinse cycle. The fabric is dried in an electronic tumble dryer. The cycle of soiling and washing is repeated several times.

Abstract

The present invention is directed to methods of reducing fabric malodor, comprising applying a water-soluble soil release polymer (SRP), as well as compositions comprising such polymers.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application 60 / 737,644, filed November 17, 2005, the contents of which are incorporated by reference in their entirety. Background technique [0003] Liquid fabric softener compositions are commonly used in the rinse cycle of washing machines to impart antistatic properties to laundered fabrics, to provide a desired fragrance and to provide fabrics with a soft, smooth and supple texture to the touch. Similarly, tablets containing fabric softener are commonly used in clothes dryers, and the fabric softener is imparted to the fabric by repeated contact during drying. Traditional softeners will mask the smell, but not completely remove it. [0004] Body odor imparts an unpleasant odor by impregnating fabrics and clothing. Such a bad smell persists even after washing. Body odor has a particular tendency to impregnate synthetic materials (which are often hydropho...
