SILVER BENZOATE.

Insufficient Data CAS 532-31-0 / ANTIMICROBIAL

Silver Benzoate is an ingredient proposed for its broad-spectrum antimicrobial properties. It combines the bacterial-killing action of silver ions with the antifungal and antibacterial characteristics typically associated with benzoate salts, aiming to inhibit the growth of various microorganisms.

Summary

Antimicrobial Antifungal Antibacterial

Science

Mechanism of Action

This compound functions as an antimicrobial agent. Silver ions are known to bind to negatively charged bacterial cell surfaces, leading to effective bacterial eradication. Concurrently, the benzoate component contributes general antibacterial and antifungal properties, impeding the proliferation of bacteria, yeast, and mold.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Silver Benzoate has not been specifically evaluated by the Cosmetic Ingredient Review (CIR) Expert Panel or the FDA for cosmetic use. While the CIR has deemed 'Benzoic Acid' and 'Sodium Benzoate' safe up to 5% in cosmetics (with insufficient data for inhalation safety), and the FDA lists elemental 'Silver' as a color additive for specific nail and professional eyebrow/eyelash products at defined maximum concentrations, these assessments do not apply directly to Silver Benzoate. The Scientific Committee on Consumer Safety (SCCS) has also issued opinions on 'micron-sized particulate Silver', finding it unsafe above certain concentrations in rinse-off (0.2%) and leave-on (0.3%) products, except for specific applications like eye shadow (0.2%), lip balm (0.2%), toothpaste, and mouthwash (0.05%). It is critical to note these opinions pertain to elemental silver and not Silver Benzoate.

Verdict

Insufficient Data

While exhibiting a plausible antimicrobial mechanism, the lack of specific clinical efficacy and safety data for Silver Benzoate itself necessitates further research to determine its suitability for precision skincare.
