Abstract
A launderable bactericidal and virucidal fabric finish formulation. The first component is a bactericidal and virucidal agent represented by formula (I): wherein n is 7; R1, R2, and R3 are jointly or independently selected from H or one of the following groups: wherein R4 is selected from CH3 or H; m is an integer from 2 to 10; p is an integer from 9 to 15; q is an integer from 2 to 10. A second component includes one or more crosslinkers and/or one or more catalysts. A third component includes one or more transition metal salts.
