Antimicrobial brush
InactiveUS6108847ACost-effectiveNon-toxic, durableBiocideAntifouling/underwater paintsBristleChemical compound
A brush having antimicrobial characteristics that inhibit bacterial growth. The antimicrobial agents, compounds or chemicals are embedded in either the body or bristles or both of the brush. Further, the present invention is a method of manufacturing a brush having antimicrobial characteristics that inhibit bacterial growth. An antimicrobial additive is incorporated in resin concentrate form into the amorphous zones of the molecular structure of the polymer from which brush handles are injection molded, thereby incorporating the antimicrobial agent into the brush handle. The antimicrobial additive in the body of the brush, incorporated in the manner above, results in substantive controlled migration from the body to the bristles, until a point of equilibrium is reached. The invention is suitable for any brush in which bristles are embedded in plastic, including toothbrushes, hair brushes, scrub brushes, toilet bowl brushes, cosmetic brushes, lip-color brushes, etc.

Encapsulation of readily oxidizable components
ActiveUS20070098853A1Prevent oxidationAvoids possible deleterious interactionDough treatmentFatty substance preservation using additivesControlled releasePlasticizer
A stabilized emulsion is employed to produce shelf stable, controlled release, discrete, solid particles or pellets which contain an encapsulated and / or embedded component, such as a readily oxidizable component, such as omega-3 fatty acids. An oil encapsulant component which contains an active, sensitive encapsulant, dissolved and / or dispersed in an oil is admixed with an aqueous component and a film-forming component, such as a protein, to form an emulsion. The emulsion is admixed with a matrix material for obtaining a formable mixture or dough. An acidic antioxidant for prevention of oxidation of the active, sensitive encapsulant, and a plasticizer which solubilizes the acidic antioxidant are included in the matrix material which encapsulates film-coated oil droplets containing the readily oxidizable component. The plasticizer, such as glycerol, provides mobility for the acidic antioxidant within the matrix material of the pellets for reaction with any ambient oxygen and malodorous amines.

Method for preventing contamination of an inner surface of a hollow glass body by alkali compounds and glass container, especially for medicinal purposes
InactiveUS7980096B2Preventing and avoiding contaminationBlock compoundPharmaceutical containersGlass drawing apparatusVitreous BodiesContamination
In order to avoid deposition of evaporating alkali compounds on an inner surface of a hollow glass body during thermal processing to form a glass container from the hollow glass body, an overpressure is provided in the hollow glass body during the thermal processing. Either rinsing the hollow glass body with a gas, such as air, or at least partially closing the glass body at one end so that sufficiently rapid pressure equilibration is avoided, can provide this overpressure. The glass containers made by these methods are especially suited for food or pharmaceuticals because they have a reduced alkali release from their inner surfaces, for example at most about 2.0 mg / l sodium oxide.
