Brief Summary

The purpose of this study is to evaluate the residual antimicrobial efficacy of one test product as defined by the difference between the number of a challenge bacterial species recovered following exposure to the test product and the number recovered when untreated (negative control). The challenge bacterial species to be used is Staphylococcus aureus (ATCC #6538) (S. aureus). Testing will be carried out using a modification of the standardized test method described in ASTM E2752-10 (2015) Standard Guide for Evaluation of Residual Effectiveness of Antibacterial Personal Cleansing Products. Bacterial recoveries will be assayed after application oftest material, using the forearms as a substrate.

Detailed Description

At least twelve test subjects (aged 18-65 years), with healthy skin will be used in this study, and will use the test product on one arm, and have the other arm untreated as the negative control. The test sites on both forearms will be inoculated with suspensions containing Staphylococcus au re us (A TCC #653 8), immediately after the 30 minute product drying time, and at approximately 2 hours and 4 hours following test material applications. The test sites will be sampled using the cup scrub procedure approximately 20 minutes following each inoculation. The log 10 microbial recoveries of treated versus untreated sites will be the basis for assessing the residual antimicrobial effectiveness of the test product.

Exclusion Criteria

1. Participation in a clinical study in the past 7 days or current participation in another clinical study.

2. Experiencing any signs/symptoms of respiratory illness, including cough, fever (body temperature of >100.0 °F) or chills, shortness of breath or difficulty breathing, persistent pain or pressure in the chest, confusion or inability to respond to external stimuli, bluish lips/face, loss of taste/smell, sore throat, headache, nasal discharge ("runny nose"), frequent sneezing, or general fatigue I body aches.

3. Current diagnosis of active Coronavirus Disease 2019 (COVID-19) or have been in close contact within the last 2 weeks of anyone who has been diagnosed as having contracted COVID-19.

6. Have known allergies or sensitivities to latex (natural rubber), metals, inks, sunscreens, deodorants, laundry detergents, cleansers, soaps, lotions, or common antibacterial agents, particularly, chlorhexidine gluconate (CHG), ethyl alcohol, and isopropyl alcohol or topical antibiotic ointments (e.g., Neosporin® or Polysporin®).

7. Have experienced hives (raised welts) as a reaction to anything that contacted your skin, with the exception of plants known to cause reactions for most humans (e.g., poison oak or poison ivy).

8. Be receiving any topical or systemic antibiotic medications during the 72-hour pre-test conditioning period or on the test day.

9. Be receiving any steroids (including steroid medications used to treat asthma) other than for contraception, hormone therapy, or menopausal purposes during the 72-hour pre-test conditioning period or on the test day.

13. Be pregnant, or have plans to become pregnant or impregnate a sexual partner once you have consented to test in this study or during the test period.

14. Any medical condition or use of any medications that, in the opinion of the Principal Investigator, or Consulting Physician should preclude patiicipation.
