1. A fabric care composition consisting of:
water;
a modified carbohydrate polymer having a weight average molecular weight of <500,000 Daltons and a Kjeldahl nitrogen content corrected for ash and volatiles, TKN, of >0.5 wt %; and
a cleaning surfactant;
optionally, a builder which is an inorganic phosphate, an alkali metal carbonate, a borate, a bicarbonate, a hydroxide, a zeolite, a citrate, a polycarboxylate, a monocarboxylate, aminotrismethylenephosphonic acid, a salt of aminotrismethylenephosphonic acid, hydroxyethanediphosphonic acid, a salt of hydroxyethanediphosphonic acid, diethylenetriaminepenta(methylenephosphonic acid), a salt of diethylenetriaminepenta(methylenephosphonic acid), ethylenediaminetetraethylene-phosphonic acid, a salt of ethylenediaminetetraethylene-phosphonic acid, an oligomeric phosphonate, a polymeric phosphonate, or a mixture or two or more thereof;
optionally, a hydrotrope which is an alkyl hydroxide, a glycol, a urea, monoethanolamine, diethanolamine, triethanolamine, calcium, sodium, potassium, ammonium and alkanol ammonium salts of xylene sulfonic acid, toluene sulfonic acid, ethylbenzene sulfonic acid, cumene sulfonic acid, and mixtures of two or more thereof;
optionally, an enzyme;
optionally, a preservative;
optionally, a perfume;
optionally, a fluorescent whitening agent;
optionally, a mineral base or a mineral acid and optionally, a dye;
wherein the modified carbohydrate polymer is a carbohydrate polymer functionalized with quaternary ammonium moieties; wherein the quaternary ammonium moieties on the modified carbohydrate polymer include: trimethyl ammonium moieties having formula (I)
