Active ingredients described include enzymes, oils, flavors, colorants, odor absorbers, fragrances, pesticides, fertilizers, activators, acid catalysts, metal catalysts, ion scavengers, bleaches, bleach components, fabric softeners and combinations thereof. Examples of packet fills include laundry detergents, bleach and laundry additives, fabric care, dishwashing, hard surface cleaning, beauty care, skin care, other personal care, and foodstuffs.

Poly(acrylic acid)-based superabsorbent polymer (SAP) in a feed stream is converted into poly(acrylic acid) (PAA) in an extensional flow device. The total energy used to degrade the SAP into PAA is less than about 50 MJ/kg SAP.

Provided are a superabsorbent polymer and a preparation method thereof. According to the present invention, a superabsorbent polymer having high centrifuge retention capacity and absorption rate may be prepared by using a specific foam stabilizer.

A leak mitigation system for a fluid-cooled computing device includes an absorbent pad having a fluid sensor connected to an absorbent material. The absorbent pad is placed in a position relative to the fluid-cooled computing device to collect fluid from the cooling system. The sensor detects the presence of a fluid absorbed by the absorbent material and the leak mitigation system implements a leak mitigation protocol to prevent or reduce damage to the computing device.

Hydrographic sheets and dip and decorator activity-kits are provided. The dip and decorator activity-kits comprise one or more hydrographic sheet formed of a water-soluble film, having decoration art formed from a non-aqueous ink or dye disposed on at least one side of the sheet, and an instruction for imparting an artistic effect to the article using the one or more hydrographic sheets. The hydrographic sheet leaves floating decoration art upon dissolution in water and wherein the floating decoration art comprises a softened and at least partially solubilized water-soluble film with decoration art for adhering to an article.

A super absorbent polymer according to the present invention has an excellent discoloration resistance characteristic even under high temperature/high humidity conditions, while maintaining excellent absorption performance, and is preferably used for hygienic materials such as diapers, and thus can exhibit excellent performance.

The present invention discloses a method for increasing absorbent capacity of a superabsorbent material (SAM) by treating the SAM with a selected multifunctional chemical agent (MCA) or a combination of a plurality of selected MCAs. The selected MCA(s) may interact with the polymer chain of the SAM through one or a plurality of mechanisms that enhance the absorbent capacity of the SAM. In various preferred embodiments, SAMs include polyelectrolytes that are made from polymerizing mixtures of acrylic acid monomer and acrylic acid sodium salt, and L-arginine or lysine is selected as the MCA.

A hydrogel particle that has an average cross-sectional diameter in the range from 1 micrometer (μm) to 1000 μm, wherein the particle includes a first polymer network with an average mesh size that allows diffusion of a molecule with an hydrodynamic radius of 1000 nanometer (nm) or less into the first polymer network and which particle includes one or more binding molecules that are immobilized by the polymer network. The hydrogel particle preferably has wherein the first polymer network has an average mesh size that prevents diffusion of a molecule with an average hydrodynamic radius of more than 1000 nm to diffuse into the first polymer network, preferably the mesh size prevents diffusion of a molecule with an average hydrodynamic radius of more than 100 nm, and preferably more than 5 nm. Methods for reducing the bioavailability of one or more soluble biological molecules in a biological system by using the described hydrogel particle.

The disclosure provides a very simple and convenient method for producing a porous material of a water-soluble polymer. The herein disclosed method for producing a porous material of a water-soluble polymer includes a step of preparing an emulsion containing a water-soluble polymer, water, and a dispersoid, wherein the water-soluble polymer is dissolved and the dispersoid is dispersed in the emulsion, and a step of evaporating and thereby removing the water and the dispersoid from the emulsion. The boiling point of the dispersoid is higher than the boiling point of water. The solubility of the water-soluble polymer in the dispersoid is lower than the solubility of the water-soluble polymer in water.

One embodiment provides a disposable tool. The disposable tool may include an exterior layer disposed over one or more dissolvable layers forming a shape of the disposable tool. The exterior layer is coated with an impermeable coating. The disposable tool includes one or more segments that are not coated with the impermeable coating. The disposable tool may be utilized for consumption of food or liquids or as an applicator, such as a tampon applicator.
