Four in-depth guides, each fully referenced. They summarise published research; where a guide gives a result for an EQ8 product, it comes from that product’s label and certificates.
Hand hygiene
Hypochlorous on hands: what the studies show
Hypochlorous and alcohol hand rubs side by side: how they compare on hands, spores and skin, how to use them, and EQ8 DEFEND’s EN 1500 result.

Mechanism
How hypochlorous attacks microbes, step by step
How hypochlorous reacts within milliseconds with the sulphur-containing parts of a microbe’s proteins and shuts down its energy supply, transport and DNA copying, and why the body makes the same molecule to fight infection.

The science
The same molecule the body makes
White blood cells called neutrophils make hypochlorous to destroy microbes they have engulfed.[6][7]
pH decides which form it takes. Below about pH 7.5 it is mostly uncharged HOCl, the form that does the germicidal work. Above it, it becomes the charged hypochlorite ion, which matters more for cleaning action.[9][10] Move the slider to see the balance shift.

Why hygiene matters
The WHO reports that hand hygiene programmes can prevent up to 50% of avoidable infections acquired during health care.[8]
