The disinfectant that clinical wards have always needed but couldn't find.

Hospital disinfection protocols have historically forced a choice: high efficacy or low toxicity. Glutaraldehyde and hypochlorites deliver the kill rates required by HAI reduction programmes but create their own clinical hazards, respiratory irritation, surface and equipment damage, and strict PPE requirements that slow turnaround times.

HOCl at 100–250 ppm is EN14476 virucidal, EN13727 bactericidal and EN13704 sporicidal. It is non-irritant to skin and mucous membranes at use concentration, safe around sensitive electronics (screens, monitoring equipment, ventilators), and appropriate for infant wards and ICU environments where chemical exposure to vulnerable patients is a primary concern.

Because breakdown is to salt and water, there is no accumulation in ward environments, no impact on indoor air quality, and no cross-contamination risk from chemical residue on patient-contact surfaces.

Clinical Zone, Concentration Reference

Recommended use concentrations by ward environment

General ward surfaces 200–250 ppm Standard
ICU & surgical prep areas 200 ppm
Infant & neonatal wards 50–100 ppm Ultra-safe
Electronics & screens 100 ppm
Medical equipment surfaces 150–200 ppm
Patient room turnover 200–250 ppm

Deployment

Where it's deployed

From high-dependency units to outpatient waiting areas, HOCl scales down to the most sensitive ward environments without changing the product.

Clinical Surface Disinfection
Bed frames, overbed tables, call buttons, door handles. Rapid 60-second turnaround between patients. No residue, no second wipe required.
Medical Equipment
Stethoscopes, BP cuffs, ultrasound probes, drip stands. Non-corrosive to plastics, rubbers and electronics at all use concentrations.
Patient Room Turnover
Full-room disinfection between patients without the ventilation wait time required by bleach or glutaraldehyde-based products. Faster discharge-to-admit cycle.
Electronics & Screens
Patient monitoring screens, infusion pumps, nursing station displays. HOCl at 100 ppm passes IEC 60529 spray-safe testing, compatible where alcohol wipes are not.
Infant & ICU Wards
50 ppm concentration is non-irritant to neonatal skin and mucous membranes. Safe for aerial application in NICU environments where standard disinfectants are contraindicated.
Surgical Prep Areas
Operating theatre surfaces, anaesthetic equipment, instrument trolleys. EN13704 sporicidal confirmation at 200 ppm, effective against Clostridium difficile spores.

Comparison

What it replaces

The three most common healthcare disinfectants and the clinical and operational problems each creates.

Sodium Hypochlorite (Bleach)
Problem
Respiratory irritant at effective concentrations. Accelerates degradation of polymer surfaces and aluminium components. Off-gassing in enclosed ward spaces affects staff and immunocompromised patients. Requires significant contact time at low-organic-load concentrations.
HOCl advantage
Non-irritant at clinical concentrations. No corrosive effect on surfaces at use dilution. No chlorine off-gassing at ambient temperature. Compatible with electronics and plastics that bleach degrades.
Quaternary Ammonium (Quats)
Problem
Biofilm resistance is an increasing problem in clinical environments, particularly in ICUs. Quat film build-up on surfaces creates a low-level persistent exposure issue. Rinse requirements add complexity to surface decontamination protocols in busy ward environments.
HOCl advantage
No biofilm resistance mechanism; attacks cell membranes through oxidation rather than charge disruption. No surface film residue. No rinse required. Appropriate for no-touch application via electrostatic sprayer.
Glutaraldehyde
Problem
Classified as a carcinogen and respiratory sensitiser under COSHH. Strict controls, enclosure requirements, health surveillance obligations and disposal restrictions create significant compliance overhead. Contraindicated in occupied ward spaces.
HOCl advantage
No carcinogenic classification. No health surveillance requirement. No respiratory sensitisation risk. Can be applied in occupied clinical areas at appropriate concentrations, removing the need to clear and ventilate spaces between treatments.
