PUR-HOCL – Start into a new era

HOCL – Hypochlorus Acid

Its mode of action in the human body

From the moment animals and plants appeared on earth, they had to deal with various threats. Among other things, these threats include pathogens. Pathogens which settle on the body surface or penetrate the body, frequently attempting to cause it harm or even destroy it. In order to face these dangers, nature took millions of years to develop a substance or, more accurately, an absolutely unique acid – hypochlorous acid (HOCL). It is a component of our immune system and is produced in the white blood cells.

The hypochlorous acid is nonspecific, i.e. the cell constituents are oxidized and the microorganisms are thereby inactivated – the germ can not become resistant*.

The special properties:

A particular challenge is the artificial production of this miracle substance of nature and the longer-term stabilizationAll trials of production in the past, such as electrolysis, gave the same results: low concentration, reduced or no shelf life, low or no purity. Presumably therefore alternative solutions are being used, mostly based on alcohol or chlorine – with all their advantages and disadvantages.

One way to make the hypochlorous acid available is the use of tablets or granules, which contain a carrier. That’s how PUR-HOCL* works. Through the reaction of the carrier with water, the hypochlorous acid is released bit by bit. This piecewise release creates a buffer effect, since not all the drug is dissolved at once. In addition, PUR-HOCL has a nearly neutral pH, which means that significantly less corrosion occurs on metals. This leads to enormous cost savings because maintenance and repair costs can be minimized. The conversion can be carried out without great (financial) effort. In addition, PUR-HOCL tablets require a minimum of storage capacity – another cost saving factor!

In addition, the wide range of applications (see below), the broad spectrum of activity, as well as the ease of use are emphasized.


In principle, hypochlorous acid is unstable. In the finished disinfectant solution, the target concentration, usually 2000ppm HOCL, is ensure for 24 hours. Afterwards, the concentration slowly decreases, depending on the container and storage. PUR-HOCL is therefore ideally suited for all customers, who can calculate for themselves what amount of disinfectant they need per day. Based on this the fitting amount of PUR-HOCL soltuion will be “produced” in-situ.
