摘要:
The present invention is directed to materials containing an enzyme inhibitor, including treated fibers, nonwovens, functional particles and processes for making these materials. These materials are useful in reducing or delaying onset of odor generation from various waste materials including human and animal elimination products.

Novel hemostatic soluble cellulose fibers for treating wound, when applied to a bleeding wound, which absorb moisture therein and are easily dissolved to thereby assist the hemostatic effect and cell adhesion to the wound of blood platelets and fibrin contained in the blood. These hemostatic soluble cellulose fibers for treating wound are prepared by treating natural or regenerated cellulose fiber with an aqueous sodium hydroxide solution, carboxymethylating it by reacting with a monochloroacetic acid solution for a definite period of time in such a manner as to give a partial degree of substitution (degree of etherification) of hydroxyl in the glucose unit constituting the cellulose molecules of from 0.5 to less than 1.0, and applying or chemically bonding a coagulating protein fibrinogen, thrombin or blood coagulation factor XIII.
摘要:
The invention relates to a method for producing a surfactant-free suspension containing hydrophobic particles and at least 50.01 wt. % of water. According to said method, hydrophobic, nanostructured particles are suspended in at least one organic solvent which can be mixed with water and has a boiling point lower than 150 °C, and said concentrated organic suspension is then intensively mixed with surfactant-free water.
摘要:
Compositions for providing controlled-release of an active material comprise a dispersant and microcapsules containing the active material. The compositions contain the dispersant and/or microcapsules at relatively low levels to avoid negatively impacting the surfaces treated with the compositions. The active material is preferably a perfume and the composition provides a controlled-release scent, along with controlling malodor when the compositions further comprise optional odor control agent. Methods of providing a controlled-release of an active material on a surface comprise the step of contacting the surface with a composition comprising a dispersant and microcapsules containing an active material.
摘要:
The present invention relates to a process for treating a lipophilic fluid contained in an emulsion of water and lipophilic fluid. The process includes the steps of pretreating the emulsion, removing lipophilic fluid from the emulsion, and purifying the lipophilic fluid to remove at least a portion of the impurities collected during the use of the emulsion. Method options are provided for each of the aforementioned steps.
摘要:
The present invention relates to a method for electrically coalescing emulsions especially those containing lipophilic fluid. The present invention is also directed to a method to treat fabrics wherein such an emulsion is created during the treatment process and requires electric coalescence prior to reuse of the lipophilic fluid.
