High Performance Laundry Cleaning with Cold Water

In North America, consumption of modified starches for the food and beverage industry exceeds 200,000 tonnes/year, and inevitably some of that food will end up spilled on clothing and other fabrics. Laundry products which can remove starchy stains on fabric are important for meeting consumer needs. Amylase, an enzyme naturally produced in the environment by microogranisms, promotes the breakdown of starch into sugars.

The Fabric and Household Care team at DuPont Industrial Biosciences (IB) is launching a new amylase enzyme that enables high performance laundry cleaning at lower temperatures. IB has developed this new enzyme, PREFERENZ™ S100, through extensive efforts in protein engineering, molecular biology and bio-processing. Tests demonstrated that detergents using the new amylase solution could clean as well at 16°C as the same detergent without the new amylase solution could clean at 32°C. A life-cycle assessment (LCA) showed a range of benefits associated with lowering laundry wash temperature from “warm” (32°C or 90°F) to “cold” (16°C or 61°F), including improved resource use, ecosystem quality and human health.

This also represents a major opportunity to improve the environmental performance of residential laundry by influencing the “use phase,” empowering end users to change behavior and manage their own footprints using this technology. The hope is that the entire liquid amylase market will adopt this as a new standard, increasing the environmental benefits of using cold wash cycles exponentially. As a result, the launch of PREFERENZ™ S100 in North America is an important milestone to support customers in their endeavors to develop more sustainable and high performance detergents.
