  • Patent number: 7615187
    Abstract: This present invention provides materials for use as solid or concentrated chemical precursors for the production of organic peroxy acids (peracids). Organic peroxy acids are formed using a precursor according to the invention when they are combined with hydrogen peroxide or a hydrogen peroxide precursor such as a percarbonate or a perborate in aqueous medium. Organic peroxy acids, such as peroxyacetic acid, are used currently to disinfect medical equipment such as endoscopes and related items.

  • Patent number: 7144551
    Abstract: Provided herein are systems and methods associated therewith for killing molds and reducing other contaminating bioburden that may include bacteria and their spores, yeast, and viruses within various dwellings including homes, office buildings, institutions, and any other enclosed space in which humans reside, either temporarily or permanently. The technology of the present invention can be used to treat vehicles, airplanes, and ships. A process according to the invention includes the generation of a gaseous oxyhalogen species and distribution of the gaseous oxyhalogen species throughout a selected dwelling. It has been unexpectedly found that the concentration level of gaseous oxyhalogen species necessary to kill molds according to the inventive methods is far below that previously recognized in the art as being necessary for the killing of such molds. Thus, mold infestations may be killed in dwellings with minimal disruption to the usual business of the inhabitants.

  • Patent number: 7005549
    Abstract: This disclosure describes unique chemical structures for use as solid or concentrated chemical precursors to the production of peroxy acids when combined with hydrogen peroxide or a hydrogen peroxide precursor such as percarbonates or perborates. Peroxy acids (peracids) such as peroxyacetic acid are used currently to disinfect medical equipment such as endoscopes and related items. It has been discovered that these structures are not currently listed in Chemical Abstracts and do not appear to be the subject of any prior art related to this or any other similar application. The specification for this claim includes chemical structures for each claimed precursor as well as means of synthesis that could be carried our by any skilled synthetic organic chemist. Practical uses for this invention include several antimicrobial applications of which at least one example is included.

  • Patent number: 6479060
    Abstract: A topical ointment pharmaceutical composition that uses a lipophilic base, a pharmaceutical active and, dispersed in the base, from about 1% to about 50% by weight of the total composition of hydrogenated non-melted castor oil in powder form. The result of using hydrogenated non-melted castor oil in powder form is a surprising pharmaceutical elegance perceived to be smoother in texture and more spreadable than an ointment made by melting the hydrogenated castor oil.

  • Patent number: 4667504
    Abstract: An apparatus for determining in vitro the penetration rate of chemicals across a biological membrane. The apparatus comprises two housings, one holding a reservoir of test chemical, and the other providing a chamber for flowing receptor solution across a membrane held in a membrane holding compartment. The membrane holding compartment comprises a cylindrical depression surrounding an open end of the receptor solution chamber. The receptor solution chamber is tilted slightly with its higher end open to the membrane holding compartment. The tilt prevents bubbles in the receptor solution from becoming stalled or trapped inside the chamber and interfering with the reliability and reproducibility of tests. An inlet bore from the upper surface of the receptor housing leads to a closed end of the chamber inside the receptor housing. An outlet bore leads from the top of the open end of the chamber near the membrane holding compartment to the upper surface of the receptor housing.
