How Germ-Block works (the technical stuff)
The active ingredient for our Hand Sanitiser is a silane-based quaternary ammonium chloride compound.
The scientific term for the process that Germ-Block uses to kill germs is called “lysis”, and it has a physical rather than a chemical mode of action.
When applied wet to skin, it dries and bonds to the surface, forming a layer of microscopic spikes that are deadly to any micro-organism.
Bacteria and viruses are electro-statically attracted to the Germ-Block spiked surface. The Germ-Block molecule then draws the microbe down onto its spike, which penetrates and ruptures the microbe’s outer cellular wall and it is forced to implode (lysis) and dies.
Since this is a “physical” kill, nothing is transferred to the now dead cell, and the spike is ready for the next microbe.
It will continue to kill over 99.99% of pathogens for the next 24 hours.
This is a representation of the Germ-Block molecule which is formed in 3 parts:
- The silane base, which anchors to the skin surface by covalent bonds, formed readily through hydrolysis reactions.
- The centrally located positively charged nitrogen.
- The long molecular chain, standing out from the base, that acts like a “sword” to rupture the microbes outer cellular wall.
This active ingredient has been tested in the UK and shown to meet the following standards:
EN 13679 EN 1276 EN 1500 EN 12791 EN 1650None of the chemicals used in Germ-Block are toxic, and it is alcohol-free, so is very gentle on your skin. It is very suitable for sensitive skins and all ethnicities.
