Enzymatic reactions for producing dextran are also disclosed.

Enzymatically polymerized gelling dextrans

A hydrocolloid or aqueous solution comprising a poly alpha-1,3-glucan ether compound is disclosed having a viscosity of at least about 10 centipoise (cPs). The poly alpha-1,3-glucan ether compound in these compositions has a degree of substitution of about 0.05 to about 3.0. Also disclosed is a method for increasing the viscosity of a hydrocolloid or aqueous composition using a poly alpha-1,3-glucan ether compound.

Use of poly alpha-1,3-glucan ethers as viscosity modifiers

An enzymatically produced α-glucan oligomer/polymer compositions is provided. The enzymatically produced α-glucan oligomer/polymers can be derivatized into α-glucan ether compounds. The α-glucan oligomers/polymers and the corresponding α-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.

Glucan fiber compositions for use in laundry care and fabric care

A colloidal dispersion is disclosed comprising poly alpha-1,3-glucan or poly alpha-1,3-1,6-glucan and a solvent. The colloidal dispersion has utility in various applications, including food, oil field, pharmaceutical, personal care and specialty industries.

Colloidal dispersions of poly alpha-1,3-glucan based polymers

The disclosure relates to products including a polysaccharide derivative wherein the polysaccharide derivative includes a polysaccharide substituted with at least one of: a) at least one sulfate group; b) at least one sulfonate group; c) at least one thiosulfate group; or d) a combination thereof; wherein the polysaccharide is poly alpha-1,3-glucan, poly alpha-1,6-glucan, poly alpha-1,3-1,6-glucan, or a mixture thereof; and the polysaccharide derivative has a degree of substitution of about 0.001 to about 3. The products can be useful as anti-deposition and/or anti-graying agents in laundry detergents, and in home care applications.

Product comprising polysaccharide derivatives

Compositions comprising oxidized dextran compounds are disclosed herein. Oxidized dextran compounds are produced by contacting dextran under aqueous conditions with at least one N-oxoammonium salt, at least one periodate compound, and/or at least one peroxide compound.
