Cleaner Protectorant Leaves Behind an Invisible Shield


Samaritan Shield Overview Graphic
  • Samaritan Shield Cleaner Protectorant leaves behind an invisible shield to reduce the spread of infectious agents.
  • Samaritan Shield formula has proven effective against multiple pathogens.
  • Samaritan Shield additive system containing NOVEX-AMGTM has demonstrated greater than 99.999% reduction of E. coli, salmonella, listeria, staph Bacillus subtilis C-Dif and pneumonia.
  • Samaritan Shield continues to protect surfaces from bacterial contamination for up to 21 days (depending on traffic in the environment).
  • Samaritan Shield is formulated with 100% responsible and sustainable materials.

Samaritan Shield's Scope:

  • Samaritan Shield Cleaner Protectorant with NOVEX AMG, promotes healthy living, a safe environment, and public health
  • Samaritan Shield Cleaner Protectorant with NOVEX AMG uses sustainable materials that are not harmful to the environment, helping to support a sustainable future

Samaritan Shield's Impact:

  • The NOVEX AMG additives used in Samaritan Shield are compatible with cleaning geometries down to micro scale tolerances to ensure complete coverage even to “Hidden” surfaces
  • Samaritan Shield is ideal for reducing bacteria, mold and mildew from surfaces contacted daily
  • Samaritan Shield Cleaner Protectorant with NOVEX AMG TM has been registered with NSF (National Sanitation Foundation) as a Class C1 cleaner.

Samaritan Shield's Scope:

  • Samaritan Shield is time effective, cleaning the surface of 99%+ of bacteria in 5 minutes
  • When used in Samaritan Shield, NOVEX AMG TM is uniquely formulated with a plasticizer to bind it to the surface for up to 21 days.
  • Due to the ability to continuously clean surfaces, Samaritan Shield will increase janitorial efficiency by reducing the need to reapply disinfectants on surfaces

The Opportunity

  • Provide antimicrobial protection between regularly scheduled cleanings
  • Increase labor efficiency by reducing the need to reapply the disinfectant to the surfaces.
  • Addresses global market driver public health concerns for bacterial resistance.

The Solution

  • Samaritan Shield provides active surface protection for up to 21 days on treated surfaces.
  • Surface treated with Samaritan Shield can improve janitorial operational efficiency by eliminating the need to reapply the disinfectant to the surfaces.

The Need

  • Current disinfectants like Oxycide and QUAT are typically effective for up to 5 10 minutes.
  • Once the disinfectant evaporates, there is no protection on the surfaces from bacteria build up over time.
  • Using Samaritan Shield can help improve operational efficiency by reducing the need to reapply conventional disinfectants to the surfaces.

Samaritan's benefits over competitors The Samaritan has no issues with corrosion. In fact, the Samaritan not only leaves a coating that is noncorrosive to the surface, but also prevents further bacteria buildup. The Samaritan has no issues with corrosion whereas this cleaner does because it has chloride as it’s primary ingredient. The length of which the Samaritan is effective on surfaces is also a benefit over Parker Lab’s products. The Samaritan is safe on all surfaces, whereas Sealed Air products are not.

Summary of Microchem Laboratory Test Results:

NOVEX AMG™ Efficacy in Various Material Hosts JIS Z 2801 Test Protocol

Samaritan Shield Overview Graphic
  • NOVEX AMG™ has been successfully added to and tested in more than 80 sample products using more than 24 unique commercially available host systems Including 7 for Samaritan Shield
  • The above figure shows that products containing NOVEX AMG™ demonstrate greater than Log 6 performance, i.e., greater than 99.9999% pathogen reduction.

Chemical Harshness Test

The Antimicrobial effects of zinc and copper based cleaners

  • Reduction of Bacillus subtilis gram-positive bacteria and Escherichia coli (E. coli) gram-negative bacteria with treatment of Samaritan Shield products vs competitive based products currently on the market, measured at time intervals of 15 minutes, 30 minutes, 5 hours, 8 hours, and 24 hours.
  • In some cases, competitive products and no-treatment control samples, grew more bacteria than could be counted.
  • Samaritan Shield Copper and Zinc wipes generated 100% bacterial reduction within 5 hours respectively.

UWW Materials and Methods

UWM-Whitewater Undergraduate Research Program
  1. Apply treatments to room temperature, sterile pans. Allow to sit for 10 minutes.
  2. Apply 2.0 x 106 per 50 µl of fresh bacteria to each square. Let sit for 15m, 30m, 5h, 8h, or 24h.
  3. Using a sterile swab: dip into sterile nutrient broth, swab entire area, put back into tube. Repeat for all squares. Incubate O/N at 37ºC on rocker.
  4. After 24 hours, create 3 dilutions per sample: 10 2, 10 4, and 10 6 dilutions using 990µl sterile PBS. Using 100µl of dilution, plate using spread plate technique on 3 plates per dilution per sample.
  5. Incubate at 37ºC O/N or on the bench over weekend. Check and record for growth.
