  • Patent number: 6251432
    Abstract: Dosage form unit is provided to deliver one or more beneficial agents into a fluid, such as liquid enteral nutritional product. The dosage form unit includes a core containing at least one beneficial agent, preferably a marker dye, which is dispersible in the fluid. The core also contains a compatible binding agent to bind the beneficial agent together. Additional components of the core may include a plasticizer, a standard flow agent, a lubricant, additional tableting aids and at least one hydrophilic agent. A latex coating encases the core. The latex coating includes a mixture containing a substantially hydrophobic base material, preferably formed from an emulsion of cellulose acetate microspheres, which is capable of defining a matrix-type membrane, and at least one hydrophilic component being dispersible in the fluid. A dispersible beneficial agent is preferred as one of the hydrophilic components of the latex coating to allow immediate release of the beneficial agent therefrom.

  • Patent number: 6217854
    Abstract: A wiping article is provided which includes an effervescent cleanser composition held within a pouch formed from a first and second substrate sheet. At least one of the substrate sheets must be water permeable. The effervescent composition is an intimate mixture of an acid material such as citric acid and an alkaline material such as sodium bicarbonate. Water contact causes the combination to effervesce. A dry surfactant such as sodium cocoyl isethionate in contact with the water and effervescing carbon dioxide results in a highly pleasant sudsing system. Skin benefit agents may be included within the composition. The effervescent action may improve deposition of the skin benefit agents onto the skin.

  • Patent number: 6171607
    Abstract: The present invention is a unique process and apparatus for making a new matrix material called a shearform matrix which results in transformation of the morphology of a feedstock. The process is characterized by increasing the temperature of a nonsolubilized feedstock carrier to a point where it will undergo internal flow, followed by upwardly ejecting a stream of the feedstock and then subjecting it to disruptive fluid shear force which separates it into separate parts or masses which have a transformed morphology. The shearform matrix may include other ingredients such as oleaginous material and actives.
