| 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 |
| 20090155197 | Goniochromic indicator for skin sealant - A skin sealant composition having a film former like cyanoacrylate and a goniochromic dye or pigment is provided. The addition of mica/metal oxide powders to the sealant formulation makes it possible to see where it has been applied, due to the mica/metal oxide's goniochromic (e.g. irridescent or pearlescent) appearance, and it is also still possible to view the underlying skin, especially from an angle at which the color is less apparent. Thus, mica/titanium dioxide or other goniochromic or light interfering particles may be used as an additive to allow for determination of complete coverage, while not significantly obscuring the incision site. | 06-18-2009 |
| 20090155327 | Self-Indicating Wipe for Removing Bacteria from a Surface - A wipe that includes a bacteriostatic agent that contains cations having an affinity for the negatively charged cell walls of bacteria is provided. The affinity of the bacteriostatic agent for the bacteria allows the wipe to capture bacteria, thereby removing them from a surface and also inhibiting their spread to other surfaces that may contact the wipe. Of particular advantage, the bacteriostatic agent may help protect against the spread or infection of pathogens without the use of chemicals, such as antiseptics or antibiotics. Still further, the wipe of the present invention also contains a solvatochromatic indicator that undergoes a color change in the presence of a broad spectrum of bacteria. Thus, when the wipe captures bacteria, the indicator undergoes a color change that signals to the user that the wipe is functioning properly. The lack of a color change may likewise provide the user with the assurance that the area is generally free of bacteria and clean. | 06-18-2009 |
| 20100150859 | METHODS OF PREPARING METAL-MODIFIED SILICA NANOPARTICLES - A method of preparing metal-modified silica particles is disclosed. Specifically, a treatment chamber is provided in which a first and a second formulation are ultrasonically mixed to prepare metal-modified silica particles. The treatment chamber has an elongate housing through which the first and second formulations flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the formulations within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the formulations being mixed in the chamber. | 06-17-2010 |
| 20100152042 | COMPOSITIONS COMPRISING METAL-MODIFIED SILICA NANOPARTICLES - A composition comprising particles with a transition metal imbedded therein is disclosed. Specifically, the ratio of particles to the transition metal is from about 25:1 to about 50:1. The composition is prepared in the presence of ultrasonic energy. The particles are selected from the group consisting of organic particles, inorganic particles, and metal particles. | 06-17-2010 |
| 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 |
| 20100292661 | Absorbent Articles with Improved Odor Control - A technique for incorporating odor control agent particles into an absorbent article is provided. More specifically, the odor control particles are “homogenously” distributed (e.g., in a substantially uniform manner) within an airformed fiber matrix of an absorbent core of an absorbent article. An absorbent core containing such a homogeneously distributed odor control particles may possess a greater surface area for contacting malodorous compounds, thereby increasing the likelihood of odor reduction. | 11-18-2010 |
| 20110081528 | Dry Wipe for Hard Surface Germ Control - Dry paper towel sheets are provided with a cleaning-related scent and a functional visual indicia to indicate the capability of the sheets to remove 99 or greater percent of germs when used to wipe hard surfaces. | 04-07-2011 |
