Presentation of the Arcyvert toilet block

The Arcyvert toilet block is a product specifically developed for better hygiene of your toilets. And all of this of course! The new composition in 2021 has been optimized. It is even more ecological and more efficient. It contains enzymes, lactic bacteria and fatty alcohol which are integrated into a vegetable support but also a scent of essential oils of lavender to perfume your toilets (and disinfect them naturally at the same time)

The enzymes have an action that promotes the cleaning of organic deposits in the toilet bowl and in the pipes. The role of lactic acid bacteria is to reduce the pH of urine in order to allow the dissolution of uric salts.

This results in better hygiene of toilets, pipes and equipment, but also less deposits and the risk of clogging. With each flush, the Arcyvert toilet block cleans, descales, shines and deodorizes your toilets, for total hygiene.

This product is supplied with a reusable plastic basket and a block. The packaging is made of cardboard made from 70% recycled material. It is 100% recyclable.

All the enzymes involved in the Arcyvert formula are produced naturally and without GMOs. The enzymes it contains contribute to the proper functioning of septic tanks and sanitation equipment.

Active ingredients : pure and natural enzymes

What are enzymes ? These are proteins that speed up reactions between molecules.

Active ingredients: natural enzymes

Are they living organisms, like bacteria ? No, they are not living organisms but they are produced by living micro-organisms such as bacteria, fungi or yeasts.

What's it point ? Enzymes are found everywhere in Nature: it is thanks to them that reactions between molecules occur, they are responsible for more than 5,000 reactions in the cell. They accelerate most reactions by a factor of more than 1,000. They are essential for cell life, digestion, cell energy, muscle contraction, respiration, etc. For example, in ruminants, gut bacteria produce an enzyme, cellulase, which digests plant cellulose.

Another example, certain diseases such as gout or phenylketonuria are caused by the absence or malfunction of an enzyme in the body.

What are their advantages ? Enzymes have 4 properties that make them essential players in the ecosystem for life.

1 - A catalytic property : An enzyme accelerates a chemical reaction and is found intact at the end of the reaction. We talk about biocatalyst to recall the fact that an enzyme is made by a living organism.

2 - Action at low concentration A very small quantity of enzyme in the medium is enough to catalyze the reaction.

3 - A very fast action. An enzymatic reaction takes one thousandth of a second. One of the most effective enzymes known to date in Nature, involved in the synthesis of the basic elements of DNA and RNA, makes it possible to accelerate this reaction which takes place in 18 milliseconds rather than in 78 millions of years!

4 - A natural action: An action under the conditions of life on earth (temperature, pressure, acidity, etc.), thus limiting the need for additional energy for the reaction to occur. Action du bloc wc Arcyvert

Why are these enzyme-based products so new ?

First of all, they act in a completely different way. Conventional chemicals will act through a corrosive effect. By simply picking up the dirt in order to drag it into the rinsing water. More cleverly, enzymes break down dirt by digesting and breaking it down. Cellulases will, for example, destroy the fibers of paper, and lipases will solubilize fats.

They are neither corrosive nor irritating, unlike synthetic chemical compounds. They are also biodegradable and have no toxic effect for the user, fauna and flora.


Usage tips

Place 1 toilet block in the plastic basket then hang it on the rim of the bowl, preferably where the pressure of the flush is weakest. A block has a lifespan of 3 to 4 weeks of use, variable depending on the water temperature, the hardness of the water, its positioning in the bowl, the humidity of the room and the daily number toilet flushes. WC block refill to be kept in the kraft bag before use.

Yes, as with all other types of home wastewater treatment systems, we certify that this product is compatible with a micro-station. 

Environmental characteristics

Essential to life, enzymes are naturally present in humans (saliva, stomach, intestine) and in any other living being; plants, animals and micro-organisms. Natural, non-corrosive and non-irritating unlike synthetic chemical compounds. They are also biodegradable and have no toxic effect for the user, the environment, the fauna and flora.

Their operation is just as much an ally of nature. Each enzyme is specific to the soils for which they are intended. This targeted action therefore does not lead to any other adverse effects or source of additional pollution. A real revolution that is healthy, efficient and a vector of ecological transition in the world of maintenance.

These enzymes also play an important role in the current health context which requires the daily use of powerful chemical detergents and disinfectants. Although necessary and indispensable, these products contribute in spite of themselves to increasing our exposure to chemical agents. Enzymatic household products thus make it possible to reduce this chemical pressure in our surroundings and our living spaces.

Precautions for use

Attention. Causes skin irritation and serious eye damage. Keep out of reach of children. Wash hands thoroughly after handling. In case of eye contact, flush cautiously with water for several minutes. Remove contact lenses if the victim wears them and if they can be easily removed. Continue rinsing. If swallowed, call a poison control center or doctor immediately.

Arcyvert, 35 years of know-how, a pioneer in ecological maintenance

Logo ArcyvertFounder Daniel Mauban began in 1979 to design cleaning products, first for septic tanks and then for sanitary facilities, based on active principles that respect the environment. Precursor of an ecological offer on cleaning products, ARCYVERT is created. This is the start of the "septic tanks - pipes" range, the formulations of which remain unchanged to this day.

The range was then extended to household cleaning products, with the birth of organic store networks in France. Working hand in hand with the organic circuit, the company has continued to grow by developing new products closer to consumer needs, while remaining on a human scale.

Today the torch has passed to the next generation: Thierry Mauban thus perpetuates the values of the family company and social commitment, in particular with the Specialized Establishment for Work Assistance (ESAT), Les Ateliers de L'Espoir in Rennes (35), for packaging.

Bonjour F Pouget,
Merci pour votre retour. La durée indiquée est une moyenne. Tout dépend surtout de la dureté (teneur en calcaire) de votre eau de réseau.
Bien cordialement,
Penn'Ty Bio

F Pouget


Efficacité et odeur bien. En revanche la durée annoncée de 21 jours est surestimée, chez moi, elle n'a pas dépassée 15 jours . Je remets une nouvelle recharge et je vais suivre précisément la durée.
