The problem it solves

A 190-year-old ideal, held back by one barrier.

Hypochlorous acid is among the most powerful and safest antimicrobial agents known to science. It is not a synthetic invention; it is the same molecule the human immune system produces to defend itself. It works across a broad spectrum (bacteria, viruses, fungi, spores, and biofilm) and breaks down into nothing more than salt and water, leaving no toxic residue.

For nearly two centuries, one barrier held it back: it would not stay stable. Conventional hypochlorous acid begins to degrade within days and carries a shelf life of roughly thirty days, too short to manufacture, store, and ship at scale.

Discovered 1834

StableHOCL™ solves that. It is a proprietary, patent-pending platform that delivers hypochlorous acid in a stable, fully potent form with a 24-month shelf life: manufacturable, storable, and shippable worldwide.

Documented to be up to 100 times more effective than antimicrobial bleach, it stays gentle on stainless steel and most surfaces and breaks down to nothing more than salt and water. The significance is structural, not incremental: by solving stability, StableHOCL™ turns a 190-year-old scientific ideal into a platform deployable across the many fields where a safe, potent, residue-free antimicrobial has always been wanted but never been practical.

Hypochlorous-acid chemistry is recognized on the WHO list of effective biocides. Where an application calls for it, named-pathogen efficacy — including Listeria, Salmonella, and norovirus — is supported by data. We publish what the platform does, never how it is made.
