What is the difference between a Disinfectant and a Sanitizer?

There is a general misunderstanding by the consuming public as to the difference between a disinfectant and a sanitizer; the perception being that they are equally effective. Factually sanitizers only kill a percentage of viruses and bacteria (99.99% often advertised) while a disinfectant kills 100%. Sanitizers are therefore only effective at reducing the number of organisms present on a surface, leaving the remaining organisms to quickly reproduce after the sanitizer’s application. Furthermore, the organisms that remain after the application of a sanitizer may become resistant to future sanitizing treatments thereby reducing the effectiveness of a sanitizer after repeated applications. PureGreen24 not only kills 100% of bacteria, it also does not introduce bacterial resistance resulting in PureGreen24 having unlimited long term effectiveness.

Why do organisms NOT build up a resistance to PureGreen24 when they do with other sanitizers and disinfectants?

PureGreen24 takes no prisoners! SDC, the active ingredient of PureGreen24, kills microorganisms by two modes of action: 1) the silver ion deactivates structural and metabolic membrane proteins leading to microbial death; 2) the microbes view SDC as a food source, allowing the silver ion to enter the microbe. Once inside the organism, the silver ion denatures the DNA, which halts the microbe’s ability to replicate and leads to its death. By totally killing the organisms there is no chance for them to build up a future resistance to SDC.

Why is using an EPA Category IV disinfectant so important verses the Toxic Category II rating of the leading brands?

The EPA does not require warnings for Category IV products, in contrast to Category II Products. Category II products must be labeled with the following warnings: May be fatal if absorbed through skin, May be fatal if inhaled, Causes substantial and possible irreversible eye injury and skin irritation. For more information about EPA toxicity ratings visit the EPA web site. Other statements like “hazardous to humans and pets” may be found on the label of the other toxic disinfectants on the market. PureGreen24 is a category IV product that contains no toxic chemicals.

Why EPA registration?

The U.S. Environmental Protection Agency (EPA) treats disinfectants as pesticides and requires all disinfectants to be registered with the US EPA for sale in the United States. In addition, disinfectants must be registered in each state where the product is sold. PureGreen24 EPA registration number is 72977-3-84364, and is registered in all 50 states and the Commonwealth of Puerto Rico.

What are germs?

Germs are microscopic organisms or agents. There are four major types of germs: bacteria, viruses, fungi, and protozoa. Hard surfaces located in public areas are breeding grounds for germs. When a person’s hand touches these surfaces, then touches their eyes, nose or mouth infection may occur. As a result of an infection cells in the body can be damaged causing disease.

What are MRSA and VRE?

Methicillin-resistant Staphylococcus aureus (MRSA or Staph) and Vancomycin-resistant Enterococcus (VRE) are two of the most widespread antibiotic-resistant pathogens that cause hospital/ public facility- acquired infections. Unfortunately, in recent times, these infections have also led to the deaths of both young and old alike. PureGreen24 is effective against VRE and strains of MRSA.

What is the difference between a Bacteria and a Virus?

Viruses are tiny infectious agents that can only reproduce inside a living cell. Outside of a living cell, a virus is dormant, but once inside; it takes over the resources of the host cell and begins the production of more virus particles. As an example, Herpes is a virus. Bacteria are one-celled living organisms. Bacteria are many times larger then viruses. All bacteria are surrounded by a cell wall. They can reproduce independently, and inhabit virtually every environment on earth, including soil, water, hot springs, ice packs, and the bodies of plants and animals. As an example, Staph is a bacterium.

What are Fungicides and Virucides?

Fungicides kill fungus, and virucides kill viruses. PureGreen24 is both a Fungicide and Virucide*.

How often should PureGreen24 be applied?

It is recommended that PureGreen24 be applied after the surface is cleaned or at least once per day. Following cleaning, the residual disinfectant properties of PureGreen24 cease (be mindful that most disinfectants have little to no residual disinfectant properties after they are applied). In the case of sports equipment and young children’s toys or equipment, is it recommended that PureGreen24 be applied after or before each use. Microfiber cloths are recommended for the application of PureGreen24.

Are Botanical based Sanitizers as effective as PureGreen24?

Beware of products that claim only 99.99% effectiveness. It is important to use a product that is 100% effective (see sanitizer vs. disinfectant answer). Furthermore, many of the so called botanical based product’s active ingredients are toxic substances. An example of a botanical ingredient is thyme; from which Phenol, a toxic substance, is extracted. Therefore when selecting a disinfecting product it is important to ensure that there is 100% effectiveness such as PureGreen24.

Can I use any bottle to apply PureGreen24?

It is important that PureGreen24 be stored only in opaque bottles (not transparent or translucent) due to the photosensitivity of silver that may cause the color of liquid to change to a slight purple color. This will not however have any negative impact on the effectiveness of the PureGreen24. We also recommend that for labeling purposes it’s good for employees to know that they are now using a safe green product. Mixing PureGreen24 with the prior toxic chemical is also not recommended.

Why Use PureGreen24 vs. Bleach + Water?

There are many steps that must be closely followed with using a bleach and water dilution; with the first step being the mixing. This is a hazardous task that is often performed incorrectly. The EPA only recognizes a MRSA kill claim from professional grade bleaches such as Ultra Clorox Germicidal Bleach (standard Clorox bleach is not EPA rated to kill MRSA). As per Clorox, the concentration of the bleach to water must be 2400ppm (or 5.33 oz of bleach per gallon of water). Once the correct bleach is mixed in the correct proportion, it must be applied by professionals using protective gear, allowed to soak for 2 minutes, and then rinsed. Often times, the soak time is too short or the toxic bleach/water mixture is not properly rinsed. Then, the general area must be allowed to “air out” prior to humans/ pets entering the space. Of course bleach is well known to stain and damage fabrics and other materials; so be prepared for collateral damage resulting from the application process. Then, do not forget to dispose of the leftover bleach/ water mix as it loses effectiveness over time (as short as 24 hours). Most likely, the disposal of the remainder is not performed in an environmentally friendly way (unused bleach-water is generally poured down the sink).

Puregreen24 has none of these disadvantages. There is no mixing, PureGreen24 has an EPA IV toxicity rating which does not require warnings by the Federal EPA; no protective gear is required, no need to rinse, it does not damage fabrics or other materials, it may be applied in the presence of humans and animals, and there is no wasted PureGreen24. Plus, PureGreen24 has the following advantages which include: its active ingredient, SDC, being EPA registered to kill MRSA, offers a 24hr residual bacterial kill, and is a human and pet friendly product.
