Definitions

  • a harmful substance may penetrate deeply into the reticulated grain structures of microscopic surfaces, making it difficult to displace.

These two products are standalone treatments for decontamination strategies. The combinations of the two in concert with one another presents a unique approach to decontamination and disinfection strategies.
  • SSDX-12 is a high potency decontamination soap specifically used for the safe decontamination of air craft.
  • SSDX-12 was required to demonstrate resistance to corrosion on aircraft metal alloys and sensitive equipment.
  • the product was also required to remove residues of chemical weapons down to an acceptable standard. While the product is demonstrably effective at treating the targeted surfaces, the challenge of remediating the now dissolved and mobile chemical agents remained. In many situations it is simply unacceptable to rinse the treatment off into the environment.
  • D7 formula (hereinafter“D7” or“D7 formula”) is a high potency
  • D7 decontamination/disinfection agent used to treat surfaces contaminated with bacteria, viruses, mold, mildew, toxic industrial chemicals, chemical weapons and other pathogenic and harmful agents.
  • D7 is able to promote the rapid chemical remediation of these threats by virtue of its unique ability to solubilize normally water insoluble targets and expose them to chemical oxidation directly or in the realm of a self assembled micellular structure embodied in the formula.
  • D7 formula extends the technology to include both oxidation reactions and reducing reactions. Additionally, D7 incorporates the treatment for toxic industrial chemicals. It also is the first reference to a bleaching activator.
  • D7 expands into the area of mold, disinfection and
  • D7 expands on the chemical landscape for DF-200. Additionally it incorporates data for rates of reaction against various toxic agents. It is also an improvement of the original DF-100 relative to performance against mustard agents in regard to reaction time and specificity. In one embodiment, D7 also integrates different bleaching activators.

  • the cleaning composition is effective to remove chemical warfare agents from the exterior surfaces of the vehicle upon application thereto.
  • a method for cleaning exterior surfaces of a vehicle using the above cleaning composition may be applied.
  • the method includes providing a cleaning composition, applying the cleaning composition to the exterior surfaces of the vehicle, and rinsing the exterior surfaces of the vehicle with water.
  • a concrete surface may look solid from our perspective but when viewed
  • the cationic quaternary amine surfactants coupled with the alkaline pH carbonated buffer system lay the pathway for a more effective penetrating delivery of the complex cleaning chemistry embodied in D7.
  • the product behaves in ways similar to the mechanisms behind hydraulic fracturing without the high pressure pumps.
  • Alkali carbonates (potassium based) interact with the predominantly negatively biased surface
  • Hydraulic channels are opened allowing delivery of the cleaning power in the form of water, peroxide, and other formulation nonionic species.
  • D7 In its ability to penetrate/eradicate biofilms vs. traditional forms, D7 provides advantages over prior technologies as well.
  • biofilms are comprised of a secreted chemical matrix that protects pathogen colonies from intruding threats. These films have nutrient causeways, respiration causeways and transpiration causeways and their precise nature is the subject of intense inquiry.
  • the physiochemical solution properties of D7 interact in such a way as to efficiently and thoroughly disrupt those surfaces.
  • the solvency properties and the oxidation from peroxide and peracetic acid species effectively“pry” open the surface of the film and in some cases aid in the defeat of the functional causeways resulting in terminal disruption.
  • Embodiments of D7 describe an enhanced chemical formulation designed for the decontamination, disinfection and renewal of surfaces exposed to chemical, biological and toxic industrial contaminants and residues. This formula improves on prior art by expanding the efficacy spectrum, decreasing treatment time, modifying chemical properties allowing for lower effective dosage and broadening the roster of chemical agents remediated by it.
  • the formulation described herein may also be applied in variable concentrations to achieve decontamination objectives (cleaning, sanitization, disinfection, high level disinfection, mold remediation, biofilm remediation, targeted decontaminati on) .
  • Embodiments of D7 aim to incremental variants designed to perform particular tasks is the intent of this effort.
  • aspects of the invention may be formulated with a Generation 1 version of Quaternary amine (ADBAC). It is thought that broadening the type of quaternary amine may bring a benefit in either efficacy against a broader range pathogens or greater effectiveness against biofilms. Of the two, biofilm effectiveness is likely the prominent value proposition.
  • ADBAC Generation 1 version of Quaternary amine
  • D7 provides a simple roster of ingredients. D7 is not made of exotic ingredients. It is assembled with common, benign, readily available materials. Their combination produces a net effect greater than the simple sum of each.
  • D7 formulation includes:
  • Adogen 477D (50% Active) 0.05 to 2.00%
  • the Generation 5 surfactants and dimethyl dialkyl quaternary amines present an enhanced structure to the micelles developed in the D7 formulation.
  • These surfactants may modify the Gouy-Chapman-Stern layer to the point of enhanced and improved ability to more rapidly solubilize agents into the micelle body.
  • the surfactants may modify the Gouy-Chapman-Stern layer that may be tied to the speed at which an agent is decontaminated, or it might be the extent of its decontamination.
  • This embodiment of the invention may have different physical properties.
  • the efficacy profile of this version will also be different.
  • the development of the efficacy profile should be from a dilute version, perhaps a 1 to 100 dilution of the final product, up to the full version.
  • the dilute version might be considered for surfaces that are already clean and devoid of biofilm presence.
  • the concentrated version would be considered for circumstances where gross filth is more prevalent (live animal facilities, processing plants, high biofilm potential places).
  • Various embodiments of the invention for different dilutions may enable various levels of applications in addition to those disclosed in FIG. 1.
  • Pathogens toxic industrial chemicals, or other undesirable substances exist unchallenged in ambient environments except by those reactive agents common to their surroundings.
  • the natural remedies for treatment of infestations include predation by organisms, hydrolysis by water, photolysis by electromagnetic radiation, absorption by the substrate and shielding of the pathogen by environmental film to name a few. If a pathogen is soluble in water, a simple rinse may suffice. The kinetic time frame for these actions can range from the immediate to very long periods of slow transition. Delivering reactive chemical activity in the form of oxidation or nucleophillic substitution is an effective treatment strategy well known in common practice. It is the route by which numerous agents deliver their efficacious dose. Once a substance is oxidized, it is generally more susceptible to environmental decay via one or more of the aforementioned mechanisms.
  • Bleach is a water based solution whose ability to penetrate and engage pathogens is limited to the physiochemical barriers embodied on the substrate being treated. If the active cidal agent cannot come into reactive proximity with the target pathogen, nothing will happen. For this reason, disinfection and decontamination agents are formulated with substances that enable the ability overcome physiochemical barriers of interfacial tension and surface energy to deliver substances to reactive proximity. Additionally, substances that are not soluble in water may not be vulnerable to reaction based on the limited exposure to reactive conditions.
  • D7 is a formula which overcomes physiochemical barriers to deliver reactive oxidation species to pathogenic targets and by virtue of its design, aid in the ability to bring resistant substances into solution where they are then vulnerable to oxidation by the mechanisms embodied in D7.
  • This new version of the formula is an enhancement of previous versions and demonstrates a more robust and effective ability to perform decontamination/disinfection tasks.
  • D7 is a decontamination agent that delivers chemical oxidation energy in a safe, dilute form for the purpose of promoting oxidation of toxins to less harmful or totally benign breakdown products.
  • D7 chemically treats toxins by promoting oxidation and by consequence speeding up the decontamination process. By itself, D7 will work to promote decontamination.
  • the application of SSDX-12 before D7 enhances the net effect by enabling of the displacement of adsorbed substances.
  • the ratio of 15: 1 equivalent dosage of D7 with SSDX-12 is desirable to achieve the targeted results with the right properties and effects on surface decontamination.
