A note on claims

EcoloxTech generators are regulated by the EPA as devices, are not registered disinfectants, and we make no efficacy claims for them or for the solution they produce. The only EcoloxTech product with disinfection claims is HOCl-AS200 (EPA Reg. No. 101112-1), used according to its label. What applies where is set out on our regulations page and in staying compliant with HOCl. Research referred to describes published studies under their own test conditions and is not a claim for any product.

What If You Could Sanitize Like Your Body Does—Without Toxic Chemicals, Harsh Fumes, or Rinse Water Waste?

That’s exactly what hypochlorous acid (HOCl) offers.
It’s not just a trend—it’s transforming sanitation in hospitals, cruise ships, food processing facilities, schools, and even home kitchens.

So, what exactly is HOCl—and why are more businesses ditching bleach for it?

What Is Hypochlorous Acid?

HOCl is a powerful disinfectant naturally produced by your white blood cells to fight infection. Efficacy claims belong to registered products used according to their labels: EcoloxTech generators are EPA-regulated devices and carry none, and the only EcoloxTech product with disinfection claims is HOCl-AS200, EPA Reg. No. 101112-1.

With EcoloxTech generators, HOCl is created on-site using just:

  • Salt (NaCl)

  • Water

  • Electricity

Through a process called electrolysis, this simple combination becomes a high-performance sanitizer, delivering 20–400 ppm of free available chlorine (FAC)—strong enough for hospitals, yet gentle enough for produce, skin, and surfaces.

How Is HOCl Different From Bleach or Alcohol?

Is HOCl Actually Effective?

Yes—and it’s backed by science, compliance, and real-world use:

✅ EPA-Registered
✅ Regulatory status depends on the specific product and how it is used; the limits that apply are set out on our regulations page. (GRAS for food contact)
✅ USDA-Compliant (used in organic processing)

It’s trusted in:

  • 🛳 Cruise lines – Norwegian Cruise Line replaced all toxic sanitizers with HOCl

  • 🏭 Food processing – Improves safety, extends shelf life, and reduces spoilage

  • 🏥 Healthcare – A safe alternative to quats and harsh surface sprays

  • 🏠 Homes & schools – Gentle enough for kids, pets, toys, and food-prep areas

Why the World Is Switching to HOCl

✅ Zero toxicity
✅ No PPE required

✅ Faster workflows
✅ Longer shelf life for food
✅ Lower chemical costs
✅ biodegradable

Bleach is fading. HOCl is the future.

How to Start Using HOCl

You can generate HOCl on site using EcoloxTech systems like:

Eco One – Compact, for home and lab use
E-300 – Mid-size, for restaurants, schools, and clinics
E-1200 – Industrial-scale, for food processors, cruise ships, and agriculture

Each system creates fresh, potent HOCl for pennies per gallon—eliminating the need to ship, store, and handle harmful chemicals.
