# Is Antibacterial Hand Soaps (Triclosan & Benzalkonium) Safe for Septic Tanks?

Antibacterial soaps contain chemical biocides (such as benzalkonium chloride) engineered specifically to eradicate bacterial colonies. While small amounts are diluted, whole-house antibacterial soap use reduces digestive efficiency in septic tanks.

## Official Wastewater Verdict on Antibacterial Hand Soaps (Triclosan & Benzalkonium)

Avoid Heavy Use — Regular Plain Soap is 100% Safer for Septic

- Status: CAUTION
- Microbial Rule: Use regular, non-antibacterial liquid soaps. The CDC confirms standard soap and warm water is just as effective at removing germs without killing septic bacteria.
- Primary Risk: High-volume commercial use of antibacterial soaps can turn septic tanks biologically sterile.
- Safe Alternative: Castile soap, plant-based soaps, and standard non-antibacterial foaming hand wash.

## Biological & Chemical Impact on Septic Bacteria

Continuous influx of antimicrobial chemicals suppresses the reproductive rate of anaerobic digestive bacteria.

High-volume commercial use of antibacterial soaps can turn septic tanks biologically sterile.

Use regular, non-antibacterial liquid soaps. The CDC confirms standard soap and warm water is just as effective at removing germs without killing septic bacteria.
