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

The disclosure relates to compositions comprising a polysaccharide derivative, wherein the polysaccharide derivative comprises a polysaccharide substituted with a) at least one hydrophobic group, and b) at least one hydrophilic group, wherein the polysaccharide is poly alpha-1,3-glucan, poly alpha-1,6-glucan, or poly alpha-1,3-1,6-glucan.

Amphiphilic polysaccharide derivatives and compositions comprising same

The disclosure relates to compositions comprising a poly alpha-1,3-glucan derivative. The poly alpha-1,3-glucan derivative is a poly alpha-1,3-glucan polymer wherein the polymer is substituted with at least one polyether group and/or polyamine group. Compositions comprising the poly alpha-1,3-glucan derivative are useful as detergent compositions.

Detergent compositions

The disclosure relates to compositions comprising a polysaccharide derivative. The polysaccharide derivative is a polysaccharide polymer wherein the polymer is substituted with at least one polyether group and/or polyamine group. Compositions comprising the polysaccharide derivative are useful as detergent compositions.

This invention relates to a method for controlling microorganisms comprising coating a surface with a removable, antimicrobial film-forming composition.

A tissue adhesive formed by reacting an aminodextran containing primary amine groups with an oxidized dextran containing aldehyde groups is described. The dextran-based polymer tissue adhesive is particularly useful in medical applications where low swell and slow degradation are needed, for example sealing the dura, ophthalmic procedures, tissue repair, antiadhesive applications, drug delivery, and as a plug to seal a fistula or the punctum.

The invention pertains to a printing form and a process for preparing the printing form from a solvent-free curable composition that includes, in prescribed relative amounts, an epoxy novolac resin; a bisphenol-A epoxy resin or a bisphenol-F epoxy resin; a monofunctional reactive diluent; a multifunctional reactive diluent; and a stoichiometric amount of an amine curing agent. The ratio of the epoxy novolac resin to the bisphenol epoxy resin is 1:3 to 3:1 by weight. The process includes applying the curable composition to a supporting substrate to form a layer, curing the layer at one or more temperatures in a temperature range, and engraving to form at least one cell in the cured layer. The process prepares printing forms, particularly gravure printing forms, having a cured resin composition layer that is engravable, resistant to solvent inks and to mechanical wear, and capable of printing gravure-quality images.

A hydrogel tissue adhesive formed by reacting an aminated polysaccharide with a water-dispersible, aldehyde-functionalized multi-arm polyether is described. The hydrogel tissue adhesive may be useful as a general tissue adhesive and sealant for medical and veterinary applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, ophthalmic procedures, drug delivery, and to prevent post-surgical adhesions. Additionally, due to the presence of the aminated polysaccharide, the hydrogel tissue adhesive may also promote wound healing and blood coagulation, and provide antimicrobial properties.

A hydrogel tissue adhesive having decreased gelation time and decreased degradation time is described. The hydrogel tissue adhesive is formed by reacting an oxidized polysaccharide containing aldehyde groups with a water-dispersible, multi-arm amine in the presence of a thiol additive. The thiol additive accelerates the process to form the hydrogel and accelerates the degradation of the hydrogel formed. The hydrogel may be useful as a tissue adhesive or sealant for medical applications, such as a hemostat sealant or to prevent undesired tissue-to-tissue adhesions resulting from trauma or surgery.

Compositions containing modified fullerenes and their use, for example, as films for membranes in electrode assemblies for electrochemical cells and fuel cells such as fuel cells are described.

Compositions containing modified fullerenes

A hydrogel tissue adhesive formed by reacting an aldehyde-functionalized polysaccharide containing pendant aldehyde groups with a water-dispersible, multi-arm amine is described. The hydrogel may be useful as a tissue adhesive or sealant for medical applications that require a more rapid degradation time, such as the prevention of undesired tissue-to tissue adhesions resulting from trauma or surgery.

Hydrogel tissue adhesive for medical use

Novel aldehyde-functionalized polysaccharide compositions containing pendant dialdehyde groups are described that are more stable in aqueous solution than oxidized polysaccharides. The aldehyde-functionalized polysaccharides may be reacted with various amine-containing polymers to form hydrogel tissue adhesives and sealants that may be useful for medical applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, preventing leakage of fluids such as blood, bile, gastrointestinal fluid and cerebrospinal fluid, ophthalmic procedures, drug delivery, and preventing post-surgical adhesions.
