  • Patent number: 8969282
    Abstract: A low odor, liquid disinfectant composition comprising multiple components, which, upon mixing, provide an aqueous solution comprising low levels of peracetic acid for use in decontaminating articles and surfaces contaminated with bacteria, viruses, fungi and other biological contaminants such as spores, including, but not limited to, Clostridium difficile (C.diff). The disinfectant composition is prepared just prior to use by combining two or more separately packaged components.

  • Patent number: 8653015
    Abstract: A solvent blend cleaner useful for reflux cleaning of chemical manufacturing equipment, including that used in manufacturing pharmaceuticals, comprises a blend of environmentally friendly and safe solvents selected on the basis of specific criteria, such as vapor pressure, vapor density, boiling point, specific heat, and heat of vaporization, among other things; achieves excellent cleaning even upon further dilution with water; and avoids the disadvantages associated with the use of conventional commodity solvents in reflux cleaning methods. Desired solvency, cleaning and wetting properties of the inventive formulations in use can be achieved through blending of solvents having the selected criteria. Additives, such as surfactants, can be added to enhance cleaning and lower solvent requirements.

  • Patent number: 7144846
    Abstract: A low pH disinfectant composition comprises an aqueous composition of a phenolic compound, an organic acid, and/or a dispersing surfactant and/or solvent. The disinfectant solution can be concentrated, or more preferably diluted ready to use, and is very effective in eradicating fungi including Aspergillus niger.

  • Patent number: 6383505
    Abstract: An antimicrobial lotion for topical use comprises an oil-in-water emulsion with a dispersant of emollient droplets in an oil phase and an antimicrobial agent in a water phase. The emollients moisturize the skin. Antimicrobial agents have a more rapid antimicrobial effect in an aqueous solution than in the oil phase. A combination of anionic and nonanionic surfactants stabilize the emulsion and maintain a cationic antimicrobial agent primarily in the water phase. The resulting lotion is gentle on the skin while providing more rapid antimicrobial effect than conventional lotions. With longer lasting antimicrobial agents, such as chlorhexidene, the lotion is rubbed into the skin and left on to continue moisturizing and killing microbes for up to 12 hours.

  • Patent number: 6090772
    Abstract: A disinfectant hand wash includes Triclosan and a reduced amount of surfactants in order to reduce skin irritation while maintaining improved activity against Gram negative and Gram positive organisms, including Serratia marcescens. The hand wash includes an effective amount of Triclosan, preferably 0.2-3.0% and a non-aqueous solvent. Hexylene glycol, or a mixture of hexylene glycol and isopropanol as the non-aqueous solvent provide improved efficacy in killing skin-born microbes. The hand wash further includes less than about 10% surfactant, preferably less than 5%. The hand wash further includes a chelating agent, a thickener, a buffering agent, and water.

The hand wash includes an effective amount of triclosan, preferrably 0.2-3.0% and a non-aqueous solvent. A mixture of hexylene glycol and isopropanol provide improved efficacy in killing skin-born microbes. The hand wash further includes 2-20% surfactant, preferrably at less than 10%. The hand wash further includes a chelating agent, a thickener, a buffering agent, and water.

  • Patent number: 5670169
    Abstract: The present invention relates to a preserved, yet non-cytotoxic alginate based hydrating gel system for the purpose of treating wounds that need moisture. Sodium carboxymethylcellulose and an alginate polymer blend impart sufficient viscosity to an aqueous solution to provide moisture to the wound. The blend reduces the cytotoxicity of a combination of preservatives incorporated into the system. More specifically, the invention relates to a wound hydrating gel comprising a) a hydrocolloid mixture of carboxymethylcellulose and sodium/calcium alginate, and b) a preservative system. This invention further relates to methods of preparing and using the wound hydrating gel.
