摘要： Compositions are disclosed herein comprising at least one dextran ether compound that comprises uncharged, anionic, and/or cationic organic groups. The degree of substitution of one or more dextran ether compounds is about 0.0025 to about 3.0. Dextran from which the disclosed ether compounds can be derived can have a weight-average molecular weight of about 50-200 million Daltons and/or a z-average radius of gyration of about 200-280 nm. Also disclosed are methods of producing dextran ether compounds, as well as methods of using these ether compounds in various applications.

摘要： Polysaccharides can be used to provide a liquid composition with desirable rheological properties while being compatible with other ingredients, such as enzymes, that may be used in formulating the liquid composition. The polysaccharides can be i) a colloidal dispersion of poly alpha-1,3-glucan, ii) poly alpha-1,3-glucan fibrids, iii) soy polysaccharide; or iv) a combination thereof.
