Clinically Studied Results
53% Reduction in BPA
57% Reduction in Triclosan
12% Improvement in Tiglylglycine
Results observed during an 8-month clinical evaluation of participants using Fireman's Friend® Hard Bar Soap as their primary daily cleanser.
Exposure Happens Every Day
Firefighters, industrial workers, first responders, and everyday consumers encounter environmental contaminants through work, products, plastics, and daily life.
Our clinical study suggests that consistent use of Fireman's Friend® Hard Bar Soap may help reduce certain contaminants measured in the body over time.
Clinical Evaluation Summary
Six participants completed a crossover evaluation followed by an 8-month extended-use study.
Researchers observed statistically significant reductions in:
- Bisphenol A (BPA)
- Triclosan
- Tiglylglycine
Analysis was conducted using paired statistical comparison of baseline and final measurements.
53% Reduction in Bisphenol A (BPA)
Participants experienced an average 53% reduction in Bisphenol A (BPA) levels.
BPA is a common environmental contaminant frequently associated with plastics, food packaging, thermal paper receipts, and other everyday consumer products. It has been the focus of increasing health concerns due to its endocrine-disrupting properties.
Study Result: Participants demonstrated significantly lower BPA levels after extended use of Fireman's Friend® Hard Bar Soap.
57% Reduction in Triclosan
Participants experienced an average 57% reduction in triclosan levels.
Triclosan was historically used in antibacterial soaps and personal care products and has been scrutinized because of concerns regarding hormonal and endocrine system effects.
Study Result: Long-term daily use of Fireman's Friend® Hard Bar Soap was associated with substantial reductions in measured triclosan levels.
12% Reduction in Tiglylglycine
Participants experienced an average 12% reduction in tiglylglycine.
Tiglylglycine is a metabolic marker associated with mitochondrial activity and cellular energy production. Lower levels may be consistent with improved mitochondrial efficiency and metabolic function.
Study Result: Researchers observed a statistically significant improvement in this biomarker over the study period.
What These Results Suggest
Environmental contaminants are encountered daily through consumer products, occupational exposures, household materials, and the surrounding environment.
The results of this clinical study suggest that regular cleansing with Fireman's Friend® Hard Bar Soap may help support the reduction of certain environmental contaminants measured in the body while promoting a cleaner skin environment.
Most notably, significant reductions were observed in both BPA and triclosan, two compounds commonly discussed in environmental health research.
Designed for Those Who Face Exposure Daily
Fireman's Friend® was originally developed to help firefighters and other high-exposure professionals remove the contaminants they encounter in the line of duty.
This clinical study provides evidence that consistent daily use may support measurable reductions in environmental contaminants while contributing to overall skin and metabolic health.
