Abstract
A dye scavenger is provided that comprises a biodegradable hydrogel formed of at least one polymer chemically cross-linked by a cross-linker. The dye scavenger removes dyes rapidly, is prepared in an environmentally friendly manner, is reusable and biodegradable and can optionally incorporate other features of laundry compositions. The dye scavenger is useful for preventing dye transfer between fabrics in laundry and for removing dyes from waste water.
