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.

Method for reducing odor using coordinated polydentate compounds

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.

Odor absorbing extrudates

A vaginal treatment composition that rapidly forms a gel when placed into contact with monovalent or polyvalent cations, such as sodium (Na) and calcium (Ca) cations naturally found in vaginal mucosa, is provided. The gel may form in less than about 1 hour, in some embodiments less than about 1 minute, and in some embodiments, less than about 30 seconds. Among other things, such rapid gelation reduces the likelihood of leakage during use. In addition, because the gel may form intravaginally, it is more likely to retain its structure and shape over an extended period of time. In this manner, the gel may provide the prolonged release of a therapeutic agent that inhibits and/or treats vaginal infection. For instance, the gel may remain within the vagina for about 2 to about 48 hours to provide the desired effect.

A therapeutic article includes a skin contact layer having a plurality of fibers forming a plurality of point-bearing surfaces configured for wear against a user's skin; a personal care composition disposed proximate the fibers; an external layer attached to the skin contact layer; and an intermediate layer interposed between the skin contact layer and the external layer, the intermediate layer being configured to activate the personal care composition, the external layer being configured to direct the activated personal care composition through the skin contact layer to treat the user.

Therapeutic article including a personal care composition and methods of making the therapeutic article

There is provided a new thermo-gelling composition made with methylcellulose and citric acid. This composition may also have an effective amount of a treating agent, which may be a medicinal agent, cosmetic agent, moisturizer, adjuvant, nutritional agent, other ingredients and combinations thereof. The composition is useful in delivering moisturizers or pharmaceutically active agents to the user in a controlled release manner through the mucosal tissues in a body cavity, or on body surfaces, or as a subcutaneously injected medicament. The composition may also be used as a replacement for the soft tissues of the body as in, for example, the foot cushion and cartilage repair.

Thermo-gelling composition

An absorbent pad configured for placement under a patient to absorb bodily fluids includes a liquid permeable cover layer, a liquid impermeable back sheet, and an absorbent structure disposed between the cover layer and the back sheet. At least one of the cover layer, back sheet, or absorbent structure incorporates a dried application of a liquid activated carbon ink having activated carbon, a binder, and a solvent, with the dried application of ink having a solids add-on level of at least about 2%. The activated carbon ink is applied in a pattern over between about 25% to about 95% of a total upper surface area of the pad and presents a visually contrasting color against a background color of the pad or a contrasting ink.

Absorbent pad with activated carbon ink for odor control

A vaginal treatment composition that employs a therapeutic agent to inhibit and/or treat vaginal infection is provided. The therapeutic agent is capable of inhibiting and/or killing(e.g.,),(e.g.,), and/or(e.g.,) pathogens. Desirably, such antimicrobial efficacy is achieved without substantially inhibiting the growth of Lactobacillus acidophilus. For instance, sugars and/or sugar alcohols may be employed in the present invention as a therapeutic agent for inhibiting and/or treating vaginal infection. In one particular embodiment, D-xylitol is used as the therapeutic agent.

Xylitol for treatment of vaginal infections

The present invention is directed to anti-microbial compositions and methods for treating fungal and yeast infections.

Anti-microbial composition and methods of use thereof

This invention concerns coatings having high surface area materials and at least one metal ion adsorbed onto the high surface area material as well as substrates having the coating and methods of applying the coating. The substrates may be films, woven fabrics or may be nonwoven fabrics. The coatings have good odor and/or gas absorbing capabilities. Nonwoven fabrics include tissues, towels, coform materials, bonded carded webs, spunbond fabrics and so forth. The substrates may be made into storage and packaging material to reduce odor and retard the ripening of fruit. The substrates may be used in personal care products, to produce clothing for military and civilian applications and many other applications.

Durable charged particle coatings and materials

A wound dressing includes a first layer located adjacent the wound and which comprises a material that is bioabsorbable, porous and adapted for serving as a scaffold for cell attachment and proliferation; and a second layer which is in contact with the first layer and which comprises an absorbent, gel forming material adapted for serving as a barrier to cell adhesion and penetration. A method of treating a wound with the dressing is also disclosed.

Bioabsorbable wound dressing

Coatings are formed by applying to article a copolymer of a water soluble base polymer having graft polymerized thereto an organic moiety that includes a group that reacts with water to form a silanol group, and then curing the copolymer to form a crosslinked hydrogel coating that is absorbent, lubricious and substantially non-water soluble. Coating compositions, coated articles the subject coatings are also described.

Absorbent, lubricious coating and articles coated therewith

There is provided a personal care product having a drying agent incorporated into it. The drying agent can reduce or control the relative humidity in the air enclosed by a personal care product significantly. Such a drying agent may be a desiccant or humectant or a combination of both. The drying agent may function using chemical or physical means and may be in fibrous, particulate or other form. The reduction of the relative humidity within a personal care product will reduce skin hydration which is believed to reduce redness and irritation due to contact with fluids.

Personal care product containing a product agent

A derivatized polysaccharide in which at least a portion of the active hydrogens originally present in the polysaccharide are substituted by monovalent aliphatic groups containing at least two carboxylic acid groups to an extent sufficient to provide a degree of substitution of at least about 0.1. The monovalent aliphatic groups contain from 4 to about 10 carbon atoms. The polysaccharide may be cellulose. At least a portion of the carboxylic acid groups present in the derivatized polysaccharide may be crosslinked permanently or reversibly. The monovalent aliphatic groups containing at least two carboxylic acid groups may be derived from 2,3-epoxysuccinic acid; 1,2-epoxypropane-1,2,3-tricarboxylic acid; 2-(epoxyethyl)-succinic acid; or mixtures thereof. Also provided is a method of preparing a derivatized polysaccharide. The method involves providing a polysaccharide; dispersing the polysaccharide in a strongly alkaline aqueous alcohol solution; adding to the dispersion an excess of an aliphatic polycarboxylic acid having an epoxy group, wherein the aliphatic polycarboxylic acid contains from 4 to about 10 carbon atoms; and heating the dispersion at a temperature and for a time sufficient to permit the reaction of epoxy groups of the aliphatic polycarboxylic acid with active hydrogens present in the polysaccharide to an extent sufficient to result in a degree of substitution of at least about 0.1. The present invention further provides a paper containing an amount of the derivatized cellulose described above sufficient to provide improved strength characteristics to the paper, compared with an otherwise identical paper which lacks the derivatized cellulose.
