New cleaning compositions including novel amphoteric dispersant polymers containing anionic and nitrogen containing substitution are disclosed. In particular, cleaning compositions containing modified polysaccharides having anionic and nitrogen containing substitution and methods of forming the same are disclosed.

Dual character biopolymer useful in cleaning products

Modified polysaccharide polymers for use as anti-sealant and dispersant. The polymers are useful in compositions used in aqueous systems. The modified polysaccharides are also useful in detergent formulations, water treatment, dispersants and oilfield applications and as fiberglass binders. Such applications include a modified polysaccharide having up to about 70 mole % carboxyl groups per mole of polysaccharide ASU and up to about 20 mole % aldehyde groups per mole of polysaccharide ASU. The applications can also include a blend of modified polysaccharides and other synthetic polymers.

The present invention relates to an environmentally friendly process for the selective oxidation of carbohydrates. The process comprises the addition of a hydroperoxide, including hydrogen peroxide, to a carbohydrate having primary alcohol groups, particularly including polysaccharides, wherein said carbohydrate is contact with a nitroxyl radical mediator and the process is catalyzed by a peroxidase enzyme in the presence of halide ions.

Process for the selective modification of carbohydrates by peroxidase catalyzed oxidation

Polysaccharide aldehydes are prepared using selective oxidation involving the use of nitroxyl radical mediated aqueous oxidation with a limited amount of oxidant and defined reaction conditions. These polysaccharide aldehyde derivatives having maximum effective aldehyde and minimal carboxylic acid levels making them especially useful as wet, temporary wet and dry strength additives for paper.

Paper comprising aldehyde modified cellulose pulp having selected aldehyde content. Another embodiment involves a method of preparing celullose aldehydes using selective oxidation with a limited amount of oxidant and a nitroxyl radical mediator and defined reaction conditions to provide oxidized cellulose material with effective aldehyde content making it particularly suitable for use in making paper with desirable wet strength, temporary wet strength and dry strength properties.

Paper prepared from aldehyde modified cellulose pulp

This invention pertains to the use of compounds containing amide or imide type functional groups to increase the rate of nitroxide mediated oxidation of alcohols, particularly primary and secondary alcohols. While suitable for oxidation of alcohol groups on a variety of substrates, it is particularly useful to oxidize cellulose, cellulose pulp or cellulose fiber such that it is commercially compatible with the traditional paper making process. Such co-catalysts may be used to increase the absolute amount of aldehyde groups on cellulose, cellulose pulp or cellulose fiber, thereby further increasing the inherent wet strength, temporary wet strength, and dry strength of paper made with such cellulose, cellulose pulp or cellulose fiber.

Use of amide or imide co-catalysts for nitroxide mediated oxidation

This invention relates to paper comprising aldehyde modified cellulose pulp prepared using nitroxyl radical mediated oxidation and further containing selected additives comprising aldehyde functional polymers or polymers containing functionality capable of reacting with aldehyde groups and having improved strength properties. This invention further relates to paper made from aldehyde modified cellulose pulp where an hydroxyl group containing polymer is added to the paper to provide wet strength properties.

Method of making paper from aldehyde modified cellulose pulp with selected additives

Stable, cold water soluble, ready for use starch aldehyde compositions and the method of preparation of such compositions wherein an aqueous dispersion of a converted starch acetal is hydrolyzed under acidic conditions to form the starch aldehyde which is then spray dried into a cold water soluble starch aldehyde powder.

Cold water soluble starch aldehydes and the method of preparation thereof

Paper prepared from aldehyde modified cellulose pulp and the method of making the pulp

A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a polysaccharide aldehyde and/or acetal at a pH of 1 to 8 to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the polysaccharide aldehyde and/or acetal with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. The method of the present invention provides permanent press properties to textiles treated therewith and increases the resistance of such textiles to future laundering abrasion. Such treated textiles display a significant reduction in wrinkles compared with nontreated textiles. Moreover, the treated textiles have a tactile sensation of feeling soft and retain their smoothness after laundering.
