The present invention includes i) an average molecular weight (Mw) of about 100,000 g / mol (preferably about 150,000 g / mol, more preferably about 200,000 g / mol) to about 2,000,000 g / mol (preferably about 1,800,000 g / mol) mol, more preferably about 1,400,000 g / mol); ii) a non-cellulose polysaccharide derivative containing at least one cationic group having a cationic degree of substitution (DS cat ) extraction of about 0.20 to about 0.30. |
