Estimating the term…
A polysaccharide conjugate comprises a polysaccharide with an attached entity having a molecular weight of at least 5000, the polysaccharide conjugate being capable of binding to cellulose. Preferred polysaccharides include tamarind seed xyloglucan, locust bean gum and enzyme modified guar. The attached entity is suitably a protein such as an enzyme, antibody or antibody fragment, or a particle possibly having a benefit agent such as a fragrance associated therewith. Because the polysaccharide conjugate binds to cellulose, which is present in cotton and other fabrics, paper, etc., binding of the conjugate to cellulose brings the attached entity into close proximity to a surface of or containing cellulose. The invention thus enables targeting of attached entities to such surfaces. The invention also provides a product incorporating the polysaccharide conjugate of the invention. The product is conveniently a laundry product such as a fabric washing product, e.g. a detergent product, or a fabric conditioning product. In this case the attached entity may be an enzyme, a particle bearing fragrance, etc. The invention also provides a method of targeting binding of an entity to cellulose by use of the polysaccharide conjugate of the invention.
A laundry detergent or a fabric conditioning product comprising a polysaccharide conjugate comprising a polysaccharide with an attached protein, said protein being selected from the group consisting of an enzyme, antibody, and an antibody fragment said protein having a molecular weight of at least 5,000 Daltons , said polysaccharide having a 1-4 linked glycan backbone structure and said polysaccharide conjugate being capable of binding to cellulose in fabric.
