Soluria™ is a company with a passion for innovative and novel product technologies that provide solutions for good health. Our team utilizes a combination of business and chemistry to seek out and find solutions for problematic issues that threaten the health and safety of people in the world of sports, dental and orthodontic care.

A key contributor to the research team at Soluria™ is Bruce Nascimbeni, Vice President, Microbiology. With a strong background in research, testing and quality control issues related to microbiology for personal care products, foods, cosmetics and pharmaceuticals, Bruce leads the Soluria™ team in product testing, and ensures that each Soluria™ product meets strict standards. Additionally, Bruce works with organizations and corporations to educate and train scientists and technicians on microbiology testing and research.

See below to learn more about some of the testing that products by Soluria™ go through before ever coming to the market.

Zone of Inhibition TestThe Zone of Inhibition Test

The Zone of Inhibition test is a screen test used to demonstrate antimicrobial activity in a visual spectrum. this test can be used to show synergy, substantivity and antagonistic properties. Results for this test are measurements of the zone where inhabition is visable. The best results are observed when the product or antimicrobial agent is water soluble and readily diffuses across the agar plate.

Bruce says…

“Our products have repeatedly demonstrated (by use of this common microbiological test) that many microorganisms are growth inhibited in the presence of the Soluria™ formulations and the active ingredients from which they are comprised.”


The Time Kill Test

A Time Kill Test determines how rapidly and effectively the antimicrobial kills the selected microorganism. For thisTime Kill Test Image test, concentration, temperature, organism type and time interval are selected based on the test sample type. Values can be reported as log-reduction or percent-reduction.

Bruce says…

“Our products have demonstrated the kill of various microorganisms by use of a time kill microbial suspension test. When our products are exposed to viable pure cultures and recovery performed at a 1 minute interval, 2 logs or 99% of the bacteria are killed. For this test, the numbers of colony forming units are converted to log 10 values and the number recovered from the test is subtracted from the control.”


The Preservative Efficacy Test

PET Test ImageThe Preservative Efficacy Test (PET) is an antimicrobial test designed to protect the consumer against microbial insult during the use of that product over time. The PET provides a microbiological evaluation of a product’s ability to kill or prevent the growth of microorganisms over a relatively long period of time. The product type determines the criteria used for passing the PET.

Bruce says…

“Our products have been challenged by the standard USP preservation efficacy test and have demonstrated a 3 log kill/reduction of the bacteria (Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus) by day 7 for a passing result. Our products also meet the critera for mold and yeast (Candida albicans and Aspergillus brazilensis) by reduction of the microorganisms of 1 log by day 14.”
