TECHNICAL FIELD

This invention relates to odor control molecules comprised of polyethyleneimine compounds containing N-halamine and derivatives thereof.

BACKGROUND

Odor control for textile substrates has been an ongoing area of investigation for decades. This invention focuses, in particular, on odor control for textile substrates comprised of cotton, polyester, and/or polyester/cotton blends, which are designed for use as activewear fabrics. Activewear fabrics are those typically worn for exercise and are often worn on a regular basis. These activewear fabrics are typically exposed to higher levels of body fluids, such as perspiration and sweat, than other types of fabrics. Over time, even with proper washing, unpleasant odor tends to build up on these fabrics and is generally difficult to neutralize by repeated laundering.

As a result, there is a continued need to improve the odor control performance of these types of fabrics. The present invention provides an odor control molecule comprised of a polyethyleneimine composition containing N-halamine and derivatives thereof which has been demonstrated to neutralize the unpleasant odors associated with activewear fabrics. Incorporating this odor control molecule in a laundry care composition provides one possible and successful delivery mechanism for deposition onto a textile substrate. Each time the textile substrates are washed, the odor control molecule is deposited on the textile substrates. Thus, the textile substrates remain smelling fresh for a longer period of time.
