Which Chemicals Are Used in a Portable Toilet for Hire?Portable toilets don’t typically bring to mind images of pristine, gorgeous-smelling facilities. Our toilets are kept as welcoming as possible through steam cleaning, the use of quality chemicals and regular servicing (including all-important toilet roll replacement!).

The chemicals we use in our chemical toilets for hire are necessary for destroying odours and maintaining high-cleaning standards in line with the most rigorous regulations.

What Chemicals Are Used in Portable Toilet for Hire?

Previously, one of the main components used in a chemical toilet was formaldehyde. This is becoming less and less prevalent, however, due to the fact that formaldehyde is an irritant to the skin, eyes and throat — not something that any toilet user should have to deal with!

Today, portable toilet chemicals are more user-friendly.


The purpose of the blue dying agent is twofold. Firstly, the dark colour helps to mask the sight of any waste, so that users don’t have to catch sight of it while “flushing”. This makes the experience much more pleasant, as the tank’s contents are hidden from view. The other benefit of the blue dye is in its colour-changing properties.

As the biocides — which prevent bacteria growth (see below) — break down, the dye slowly changes colour from blue to green. This indicates that the deodourising properties are no longer in full effect. Of course, we service all of our chemical portable toilets for hire before this happens, so that no user ever has to worry about having anything less than a perfectly sanitary experience.


Arguably the most important element, biocides prevent the growth of any odour-producing bacteria present in waste. With the use of biocides, these odorous Gram-positive bacteria are unable to thrive when covered by the chemical compounds present in the chosen synthetic biocide.

These types of chemicals are commonly used in everyday life — including swimming pools, as Chlorine is a biocide — and they are, therefore, completely safe for human proximity. The use of this chemical in the mix means that the portable chemical toilet doesn’t need to be serviced every single day — saving both time and money.


When the chemicals are released to deal with the sanitisation and deodourisation of waste, it is important that they are as effective as possible and work in the most efficient way. This is where surfactants come in.

These chemicals are compounds that lower the surface tension between two interfaces — in this case, the chemical liquid and the solid or liquid waste. The fragrances and biocides get to work much faster to create a more pleasant toilet experience. Surfactants may also be known as detergents, and other examples include other common forms of dispersants and emulsifiers.


Of course, fragrances play a key role in the use of any chemical toilet. While the biocides prevent much of the possible odour, fragrances mask any residual odour with its own scent. It’s even possible to choose the scent used in a chemical toilet for hire (and there are many to decide from).
