Borates Patents (Class 424/660)
  • Patent number: 5587221
    Abstract: A process for pretreating a carpet to give the carpet insecticidal, fungicidal and bacteriacidal properties, and the resulting carpet product. The process is incorporated into the carpet manufacturing process to eliminate the necessity of treating carpets subsequent to the manufacturing process. A portion of the carpet is saturated with a mixture comprising boric acid and a boron-containing salt dissolved in an aqueous solvent. A heat drying step is then used to drive off the aqueous solvent after which a portion of the boron-containing salt remains on the backing. The preferred mixture contains a combination of boric acid and borax in an aqueous solution. The ratio of boric acid to borax ranges from 0.5:1 to 3:1, and the percent strength of the borax/boric acid combination in the solution is preferably from 0.1% to 3.125%.

  • Patent number: 5525147
    Abstract: Methods and compositions for protecting wooden members (components) against attack by destructive insects and fungi. The wood preservative is formulated as a paste and is applied in that form to an exposed surface of the member. The active ingredient is released by that same moisture which creates conditions conducive to destructive attacks on the wood. Boron-based active ingredients are preferred as are polyethylene glycol carriers for the active ingredient.

  • Patent number: 5514287
    Abstract: A novel method and compositions are disclosed for the treatment of water in recirculating water systems. The method includes providing a boron level of at least 20 ppm in the water, continually eroding into the water a compressed sanitizer/algicide component including a halogen source material, a boron source material, and glycoluril, and periodically adding to the water an oxidizing clarifier comprising a chlorine source material, a non-halogen, chlorine source material, and a boron source material. The invention also provides novel water treatment chemicals including the compressed sanitizer/algicide component and the clarifier useful in the foregoing system. The system and compositions are safe and reliable, control algal and fungal growth and generally provide improved water quality for recirculating water systems.

  • Patent number: 5505953
    Abstract: Water-soluble borate-polyol complexes are useful as buffers and/or antimicrobials in aqueous ophthalmic compositions, including those containing polyvinyl alcohol. These compositions have greater antimicrobial activity than comparable compositions containing typical borate buffers and unexpectedly increase the antimicrobial efficacy of other antimicrobial agents when used in combination. In addition, use of the borate-polyol complexes avoids the incompatibility problem typically associated with the combination of borate buffer and polyvinyl alcohol; therefore, the compositions disclosed herein may also contain polyvinyl alcohol.

  • Patent number: 5449658
    Abstract: The growth of algae, fungi and pathogenic organisms in commercial and recreational waters, such as cooling towers, swimming pools and spas, may be controlled by adding to the water a primary sanitizing agent, preferably poly(hexamethylene biguanide) ("PHMB"), and a potentiating adjuvant comprising a calcium ion-chelating agent, preferably ethylenediamine tetraacetic acid ("EDTA"), in amounts such that the adjuvant renders the composition algicidal and fungicidal in water. The water may be further treated with a peroxy salt as a backup agent, preferably sodium perborate, or the calcium ion-chelating agent and peroxy salt may be combined as a shock treatment to water being treated with the primary sanitizing agent.

  • Patent number: 5407685
    Abstract: A film for releasing at least one of an anti-microbial agent, oxygen, and a medicament includes a flexible, porous layer (18) such as a woven, non-woven, or knitted cloth or a layer of open cell foam. A first dry reagent (12) and a second dry reagent (14) which react in the presence of a dilutant to form the anti-microbial agent, oxygen, or medicament attached to the flexible, porous layer. In one preferred embodiment, the two dry reagents are disposed on opposite sides of the flexible, porous layer such that the flexible porous layer keeps the two apart and prevents a premature reaction. Porous outer layers (20, 22) prevent the powdered reagents from being wiped off while permitting dilutant access. In a preferred embodiment, the powdered reagents include acetylsalicylic acid and a perborate which react in the presence of water to generate peracetic acid (an antimicrobial agent which breaks down in a matter of minutes to hours into oxygen) and salicylic acid (a topical keratotic).
