The invention relates to oxidized starch, to a method of preparing oxidized starch and to the use of the oxidized starch in various applications.

This specification discloses a potato starch modified to have a narrow carboxylation and viscosity profile, and sulfite levels that are below detection levels by titration. The disclosed starch forms thermal-reversible gels having a fast gelling rate and that are useful in imitation cheese

Depressants comprising a moderately oxidized polysaccharide having about 0.05 to about 4.5 mmol of anionic charge per gram at a pH of about 6 to about 7, or about 0.2 to about 5 mmol of anionic charge per gram at a pH of about 10 to about 11.2, are provided. Also disclosed are processes for enriching a desired mineral from an ore comprising the desired mineral and gangue, wherein the process comprises carrying out a flotation process in the presence of one or more of the depressants.

Disclosed herein are detergent compositions that comprise at least one (i) glucan derivative and/or (ii) oxidized polysaccharide derivative. A glucan derivative of (i) can be substituted with at least one organic group that comprises a carboxylic acid group or a sulfonate group, and the degree of substitution (DoS) of the glucan derivative with the organic group can be about 0.1 to about 3.0. An oxidized polysaccharide derivative of (ii) can be produced by contacting a polysaccharide derivative under aqueous conditions with at least one agent that is capable of oxidizing the polysaccharide derivative. The polysaccharide derivative for oxidation has a degree of substitution (DoS) up to about 3.0 with at least one organic group. Further disclosed are various applications and products employing detergent compositions.

The present invention relates to a polymer dispersion, which comprises polymer particles dispersed in an aqueous continuous phase. The polymer particles are obtainable by a radical polymerisation of one or more vinyl monomers comprising alkyl (meth)acrylates. A rosin component is dissolved into at least one of the vinyl monomers before the radical polymerisation of the vinyl monomers, and the radical polymerisation is conducted in the presence of the rosin component. The invention relates also to the use of the polymer dispersion for surface sizing of a cellulosic fibre web and to a method for producing a polymer dispersion.

Body tissue and structures in an airway may be treated with an artificial scab comprising an inhomogeneous, uncohesive, solid sheet-like body comprising a granular mixture of chitosan and polysaccharide particles. The artificial scab breaks apart into smaller pieces if peeled away from the surgical site or wound, thus reducing the risk of airway occlusion.
