"Formaldehyde was yesterday, HOCl is today!"

Formaldehyde is a widely used chemical in industry for disinfection, but it also carries risks, such as carcinogenic and irritant effects. Formaldehyde is the active ingredient in the well-known formalin. Fortunately, there is a safe alternative: hypochlorous acid (HOCl). HOCl is a naturally occurring acid produced by our own immune system. It has proven to be an effective disinfectant that is safer for humans, animals and the environment than Formaldehyde. In this article, we discuss the benefits of HOCl, how it works and how you can safely implement it in your business.

What is HOCl?

Hypochlorous acid (HOCl) is a naturally occurring acid produced by white blood cells. It is a powerful disinfectant and has been used for many years in the medical world to fight infections. HOCl has a broad spectrum of action and can kill bacteria, fungi, yeasts and viruses. It is also effective against spores and biofilms.

Why is HOCl better than formaldehyde?

There are several reasons why HOCl is better than formaldehyde/formalin:

Unlike formaldehyde, HOCl is not carcinogenic. It can be safely used for disinfection and has no negative effects on human and animal health.

No residual products
When formaldehyde is used, residual products are formed that can be harmful to the environment. HOCl, on the other hand, decomposes into water and salt, leaving no hazardous substances behind.

More effective against biofilms
Biofilms are a community of microorganisms that adhere to surfaces and are difficult to remove. HOCl is more effective than formaldehyde in removing biofilms, making it a better choice for disinfecting surfaces contaminated with them.

No hazardous residue on surfaces
HOCl leaves no hazardous residue on surfaces, making it safe for humans and animals to enter treated areas after disinfection.

Immediate use
HOCl can be used immediately for disinfection, whereas formaldehyde must be prepared first.

How is HOCl produced?

HOCl can be produced independently with Watter's disinfection machine. The machine uses electrolysis to produce hypochlorous acid (HOCl). The Watter system requires only electricity, salt and water to make an effective disinfectant, therefore it is low in maintenance costs.

Implementation in the business

Implementing a Watter system in the business process is made quite easy for you, this is because Watter's microbiologists help you transition step by step with the installation of the machine. Furthermore, measurements are also taken to check that everything is adjusted properly.


In this article, we discussed why HOCl is better than formaldehyde as a disinfectant. HOCl is safer, more effective against biofilms and does not leave a harmful residue on surfaces. It is used in a variety of industries, including medical, food and hospitality. HOCl is an effective and safe alternative to formaldehyde and is preferred for disinfection.
