EN 17126 sporicidal contact time

One molecule for surfaces, hands and water systems.

Hypochlorous acid is part of the body's own immune response, released by white blood cells to destroy pathogens. It kills bacteria, viruses, fungi and spores quickly and effectively, while remaining safe to both people and sensitive environments.

SPT95™ has passed full virucidal activity under EN 14476, the highest of the three main levels of virucidal activity in the standard, and EN 17126 sporicidal testing with a one-minute contact time. Its antimicrobial efficacy is certified in independent UKAS accredited laboratories.

In water systems, SPT95™ has been proven to rapidly eradicate Legionella and Pseudomonas aeruginosa. It clears biofilm without turning off the supply and removes the need for pasteurisation, with energy savings of up to 20% for institutions such as hospitals.

C. difficile Spores
EN 17126 sporicidal efficacy in one minute against Clostridioides difficile, Bacillus cereus and Bacillus subtilis spores.
Hand Hygiene
SPT95™ is used in hand rub formulations at 1,000 ppm.
Water Systems
Proven to rapidly eradicate Legionella and Pseudomonas aeruginosa, clearing biofilm without turning off the supply.
Fungi & Yeasts
EN 13624 efficacy against Aspergillus brasiliensis, Candida albicans and Candida auris.
Respiratory Viruses
Tested to EN 14476 against human coronavirus 229E and influenza A H1N1 and H5N1.

Comparison

How SPT95™ compares

SPT95™ against the chemistries it is most often measured against.

Other HOCl Products
The limitation
Often a mixture of HOCl with sodium, chloride, hypochlorite and stabiliser salts. Typically 500 ppm maximum, 30% maximum purity and a 3 to 6 month maximum shelf life. Stabilising salts can corrode machinery such as fogging and dosing sprayers.
SPT95™
HOCl and water only, customisable up to 32,000 ppm, minimum 95% purity and no corrosivity in use.
Chlorine Dioxide (ClO₂)
The limitation
Slower, with longer contact times. Produces chlorites and chlorates, which are harmful and highly regulated. Pre-mixed solutions are not suitable for long-term storage, and on-site generation relies on precursor chemicals classified as Dangerous Goods.
SPT95™
Fast acting with short contact times. Produces no harmful by-products and is non-toxic. Stable at concentrations up to 32,000 ppm and non-hazardous for transport and storage.
Chlorine & Hypochlorite
The limitation
Barely penetrate the biofilm that shields pathogens. They bring corrosivity, handling hazards, disinfection by-products and fast decay, forcing continuous over-dosing and pH balancing.
SPT95™
Neutrally charged HOCl penetrates biofilm and kills the microorganisms embedded in it. No THMs, HAAs or chlorate. Low corrosivity and pH-agnostic across a wide range, so no pH-correction chemistry is needed.
