20090054859 | Method for Reducing Odor Using Metal-Modified Silica Particles - A method for reducing odor is provided. In one embodiment, the method comprises modifying the surface of silica particles with a transition metal so that the silica particles are bonded to the transition metal through a covalent or coordinate bond. The method further comprises contacting the modified silica particles with an odorous compound, the transition metal facilitating the capture of the odorous compound. | 02-26-2009 |
20090117075 | Temperature Responsive Delivery Systems - There is provided a new aqueous temperature responsive delivery system made with a temperature responsive polymer and a bioadhesive which is intrinsically cationic. This system may also have an effective amount of a treating agent, which may be a medical or cosmetic agent. The bioadhesive, temperature responsive delivery system is useful in delivering moisturizers or pharmaceutically active agents to the user in controlled release manners, through the tissues in a body cavity. | 05-07-2009 |
20090124925 | Vein Identification Technique - A technique for identifying a vein in a patient is disclosed. The technique involves the application of a thermochromic ink to a venous area on the skin of a patient (e.g., human or animal). The thermochromic ink comprises thermosensitive color-changing microcapsules that contain a proton-accepting chromogen and a desensitizer. The desensitizer possesses a melting point above which the chromogen is capable of becoming protonated, thereby resulting in a color change. Thereafter, the venous area is observed for the color change. | 05-14-2009 |
20090157022 | ABSORBENT ARTICLES HAVING A WETNESS INDICATOR - Absorbent articles including a wetness indicator are generally described. The wetness indicator of the present invention is configured to expand toward the skin of the wearer (i.e., in the z-direction of the absorbent article perpendicular to the plane of the absorbent article) upon contact with a liquid. However, the expansion of the wetness indicator is substantially limited to the z-direction. That is, the wetness indicator does not substantially expand in any direction parallel with the plane of the article (i.e., the x- and y-directions). As such, the wetness indicator does not significantly interfere with the absorbent capabilities of the absorbent article. Thus, the wetness indicator can be included within conventional absorbent articles without significantly sacrificing the absorbency characteristics of the article. | 06-18-2009 |
20090157032 | ABSORBANT ARTICLES HAVING A COMPRESSED TABLET - Absorbent articles including a compressed tablet are generally described. The compressed tablet of the present invention is configured to expand toward the skin of the wearer (i.e., in the z-direction of the absorbent article perpendicular to the plane of the absorbent article) upon contact with a liquid. However, the expansion of the compressed tablet is substantially limited to the z-direction. That is, the compressed tablet does not substantially expand in any direction parallel with the plane of the article (i.e., the x- and y-directions). As such, the compressed tablet does not significantly interfere with the absorbent capabilities of the absorbent article. Thus, the compressed tablet can be included within conventional absorbent articles without significantly sacrificing the absorbency characteristics of the article. | 06-18-2009 |
20090240220 | Compressed Substrates Configured to Deliver Active Agents - A compressed substrate having an altered upper surface is generally disclosed. The compressed substrate is configured to expand in the z-direction upon contact with a liquid to form an expanded substrate without substantially expanding in either the x-direction or the y-direction. The altered upper surface of the expanded substrate has an expanded surface area that is at least about 110% of the initial surface area of the compressed substrate. The compressed substrate is constructed from a compression molded web and includes an active agent. The compressed substrate can be included within the construction of an absorbent article to transfer the active agent to a wearer. The upper surface of a compressed substrate can be altered after formation of the compressed substrate. Alternatively, the upper surface of the compressed substrate can be altered during the compression process. | 09-24-2009 |
20090299312 | Twisted, Compressed Substrates as Wetness Indicators in Absorbent Articles - Absorbent articles including a twisted, compressed substrate are generally described. The twisted, compressed substrate of the present invention is configured to expand toward the skin of the wearer (i.e., in the z-direction of the absorbent article perpendicular to the plane of the absorbent article) upon contact with a liquid. However, the expansion of the twisted, compressed substrate is substantially limited to the z-direction. Also, upon contact with a liquid, the twisted, compressed substrate unwinds to penetrate through the absorbent core of the absorbent article to reduce any pressure put on the absorbent core during expansion. | 12-03-2009 |
20100120644 | Single Phase Color Change Agents - There is provided a color change composition that remains stable in a single phase and that contains an indicator that produces an observable color change after a period of time to show that sufficient cleaning has been done or to indicate the thoroughness of the cleaning. This use indicating color change is useful for, for example, in soap for teaching children to wash their hands for a sufficient period of time. This composition may be added to many different base materials to indicate time of use or as a way to introduce enjoyment to the activity. | 05-13-2010 |
20100147203 | Three-dimensional Wiping Substrate And Method Therefor - A planar substrate has a moisture activated shrinking filament applied thereon. When wetted, the shrinking filament shrinks and causes the planar substrate to gather and pucker. The planar substrate with the filament thereon may be compressed into a compact shape when in a dry state. | 06-17-2010 |
20100152642 | Absorbent Article Saturation Indication System and Method - An absorbent article includes an absorbent body in contact with a moisture activatable shrinking yarn in the form of a metering string. The metering string includes a hanging portion that is at least initially visible to a user when the absorbent article is in use. By observing the change in length of the hanging portion, a user wearing the absorbent article can determine how saturated the absorbent article has become. The metering string may be used with absorbent articles such as tampons and diapers. | 06-17-2010 |
20100211034 | ODOR ABSORBING EXTRUDATES - This invention concerns extrudates having high surface area materials and at least one metal ion adsorbed onto the high surface area material. The extrudates may be breathable films, multilayer laminates and pultruded articles. The extrudates may be made into storage and packaging material to reduce odor and retard the ripening of fruit. The extrudates, if in the form of a breathable film or multilayer laminate may be used as outer cover material for personal care products like diapers, adult incontinence products, training pants and the like. The high surface area particle-containing extrudate may be made by adding modified nanoparticles to a filler before the filler is treated with a fatty acid. Alternatively, a filler previously treated with a fatty acid may be modified by subjecting the filler to sonic energy in the presence of an aqueous solution of metal ions and nanoparticles. | 08-19-2010 |
20100275915 | METHOD FOR REDUCING ODOR USING COORDINATED POLYDENTATE COMPOUNDS - A method for reducing odor is provided. The method comprises forming a coordination complex between a transition metal and a polydentate compound, and contacting the coordinated complex with an odorous compound. The transition metal provides one or more active sites for capturing the odorous compound. In some embodiments, the polydentate compound may be a polyalkylimine, such as polyethyleneimine, polypropyleneimine, or a dendrimer thereof. | 11-04-2010 |
