SoChlor - Hypochlorous acid releasing NaDCC Tablets

GVH_1021

Smarter Antimicrobial Technology

The UK’s most widely used NaDCC disinfectant range

SoChlor holds over 70% of NHS demand for NaDCC chlorine tablets, making it the UK’s most widely used NaDCC disinfectant range and one of the most extensively adopted infection prevention and control (IPC) solutions in UK healthcare.

Over 70% of NHS demand

A trusted, widely adopted NaDCC disinfectant range supporting environmental hygiene and infection prevention across the NHS.

GV Health’s range of hypochlorous acid-releasing NaDCC disinfectant tablets delivers broad-spectrum antimicrobial performance across healthcare and other public settings.

The active biocide, hypochlorous acid (HOCl), is a biomimetic compound also produced naturally by the human immune system. It provides effective antimicrobial action, supporting applications from routine surface disinfection to high-level pathogen control, in accordance with the relevant product efficacy claims and instructions for use. Combined with straightforward preparation and cost-efficient dosing, SoChlor helps healthcare teams break the chain of infection and achieve better outcomes in infection prevention and control.

The science behind SoChlor’s antimicrobial performance

SoChlor’s powerful antimicrobial performance is driven by hypochlorous acid (HOCl), a highly effective biocide generated in situ when sodium dichloroisocyanurate (NaDCC) dissolves in water.

NaDCC acts as a reservoir of hypochlorous acid through a reversible chemical equilibrium, replenishing the active biocide as it is consumed. This distinctive delivery mechanism helps SoChlor maintain antimicrobial activity in the presence of interfering organic matter, providing advantages over certain conventional disinfectant chemistries.

Biomimetic chemistry. Broad-spectrum disinfection.

Hypochlorous acid is also produced naturally by the body’s white blood cells as part of the immune response to pathogens. SoChlor harnesses this same antimicrobial chemistry to deliver broad-spectrum disinfection, with demonstrated activity against challenging microorganisms, including mycobacteria, non-enveloped viruses and bacterial spores, subject to the relevant product efficacy certifications and conditions of use.

Unlike sodium hypochlorite solutions commonly associated with household bleach, NaDCC generates hypochlorous acid through a reversible equilibrium. Differences in the active chemical species and their availability can influence antimicrobial performance, particularly under dirty conditions.

Intelligent Delivery of Active – Molecular Dosing

When sodium dichloroisocyanurate (NaDCC) dissolves in water, it establishes a reversible chemical equilibrium, initially releasing only a proportion of its available hypochlorous acid (HOCl).

Continual release. Sustained antimicrobial activity.

As free hypochlorous acid is consumed through reactions with pathogens and other materials, the equilibrium shifts to release more. This replenishment mechanism helps maintain the availability of the active biocide, supporting effective disinfection even in challenging conditions.

Tablet Formulation

Less packaging. Less storage. Simpler preparation.

SoChlor’s compact, lightweight tablet format allows more disinfectant doses to be transported and stored in significantly less space than equivalent liquid products. This reduces packaging and transport requirements, helping lower the associated carbon footprint.

With disinfectant solutions prepared on-site as required, SoChlor also helps minimise unnecessary preparation and unused solution waste.

Rapid dissolutionTablets dissolve quickly in cold water, making solution preparation simple and efficient.

Clean, less intrusive odourA more pleasant user experience compared with some traditional disinfectant tablets.

Clear, residue-free solutionsDissolves to form a transparent disinfectant solution without insoluble tablet residues.
