  • Publication number: 20070175484
    Abstract: An improved condom is provided by coating the inner and or outer surface of the condom base with a dissolvable element containing an agent material for delivering the agent material during sexual intercourse. The dissolvable element is made of dissolvable polymer material and/or complex carbohydrate material which are food grade materials and have selected dissolution properties, such that it remains in substantially solid form before use, and dissolves due to human body temperatures and moisture during use to release the agent material in a desired timed release and dosage. The dissolvable element is preferably a film made of polyvinyl alcohol, polyethylene oxide, hydroxypropyl methyl cellulose and/or carboxymethyl cellulose. The dissolvable element may be formed as a single layer of film or a laminate of different film layers for compound release properties. The dissolvable element is at least partially foamed using inert gases, such as nitrogen, to adjust its dissolution properties.

  • Patent number: 5529782
    Abstract: A dissolvable element containing an agent material is used for local administration of the agent material in an internal body area. The dissolvable element is made of dissolvable polymer material and/or complex carbohydrate material which are food grade materials and have selected dissolving properties, such that it remains in substantially solid form before use, and dissolves due to human body temperatures and moisture during use to release the agent material in a desired timed release and dosage. As a contraceptive, the dissolvable element is preferably a film made of polyvinyl alcohol, polyethylene oxide, hydroxypropyl methyl cellulose and/or carboxymethyl cellulose. The dissolvable element may be formed as a laminate of different film layers for compound release properties, or it may be ground into particles and incorporated in a tampon or suppository. The dissolvable element may be foamed as a means for increasing its dissolution rate.

  • Patent number: 4329246
    Abstract: Alkaline dishwasher detergent composition having a specific critical pH, and a relatively high level of available chlorine, buffered with trisodium phosphate, containing a tripolyphosphate or pyrophosphate sequestering builder, and having a relatively high level of surfactant. The detergent composition is substantially free of highly alkaline materials and organic builders and preferably contains 2.0r alkali metal silicate and/or a preferred C.sub.17 -C.sub.19 polyethoxylate surfactant.

  • Patent number: 4207197
    Abstract: Granular detergent compositions containing alkali metal polyphosphates are prepared by spraying an aqueous sodium silicate solution onto anhydrous alkali metal polyphosphates and optionally onto other dry ingredients, said aqueous sodium silicate solution containing from about 2% to about 20% by weight of a hydratable salt.

  • Patent number: 4123395
    Abstract: Bleach-free detergent compositions for use in automatic dishwashers comprising an alkoxylated nonionic surface-active agent and a sulfonated aromatic compatibilizing agent. Preferred nonionic surfactants include ethoxylated nonionics and preferred compatibilizing agents can be selected from xylene-, toluene-, cumene-, benzene-, trimethylbenzene-, ethylbenzene- and ethylmethylbenzenesulfonate. The instant compositions possess enhanced anti-redepositon properties for soils composed of grease and grease-protein complexes thereby providing impeccably cleaned objects which are virtually free of spots and streaks.
