The Application of a Nuclease Enzyme to Clean Stubborn Soils and Odors in Laundry

The inclusion of a nuclease, a new-to-laundry enzyme class in detergent formulations, reduces the concentration of recalcitrant soils on dirty clothing. Nucleases target extracellular DNA that, albeit present in minor quantities in soiled laundry items, disproportionately contributes to the accumulation of sebaceous soils and other compounds that affect the appearance of clothes. These lingering soils accumulate over multiple wear cycles and provoke a dingy appearance in clothing, characterized by dull colors, yellow staining, and an unpleasant malodor. The single and continued use of a nuclease in detergent formulations offers increased removal of these recalcitrant soils to produce less malodorous and visually preferred textiles. Furthermore, the nuclease is effective across different detergent forms, as well as in cotton short washing cycles, enabling improved cleaning in more sustainable laundry washing conditions.
