Patents (Amendment)
Ordinance, 2004: NO
Laundry treatment products comprise a graft polymer benefit agent and at least one additional laundry cleaning
ingredient. The graft polymer benefit agent preferably provides soil release or fabric care benefits. The graft
polymer benefit agent comprises a polysaccharide backbone and a plurality of graft chains extending from the
backbone, each graft chain having a degree of polymerization between 5 and 250. The graft polymer is
substantially free of cross-linking and has a degree of substitution of grafts across a bulk sample in the range of
from 0.02 to 1.0. The graft polysaccharide copolymers may be prepared using living-type free radical
polymerization techniques which provide control over the degree of substitution, the graft/co-block composition
and structure.
