A polysaccharide for a detergent formulation, wherein the polysaccharide comprises a polysaccharide backbone functionalised with carboxylic acid groups, or salts or esters thereof, and sulfur-containing groups, or salts or esters thereof;
- wherein the polysaccharide backbone is selected from the group comprising, or derived from, maltodextrin, starch and hydrolysed starch.
A polysaccharide according to any preceding claim, wherein the polysaccharide has an average molecular weight of between 1 and 50 kDa before functionalisation with the carboxylic acid groups, or salts or esters thereof, and the sulfur-containing groups, or salts or esters thereof.
A polysaccharide according to any preceding claim, wherein the carboxylic acid groups, or salts or esters thereof, and the sulfur-containing groups, or salts or esters thereof, are present in a molar ratio of between 4:1 and 1:2.
A polysaccharide according to any preceding claim, wherein the polysaccharide backbone has a total degree of functionalisation of at least about 1.4, and/or a degree of functionalisation by sulfur-containing groups, or salts or esters thereof, of less than about 0.4.
