Presentation of the Arcyvert toilet block

Natural enzymes Arcyvert

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. Even greener and more efficient. It contains enzymes, lactic bacteria and fatty alcohol which are integrated into a vegetable support but also a perfume of essential oils of lavender to perfume and disinfect your toilets (one of the many properties of lavender)

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.

These enzymes have been integrated for several years in sanitizing and descaling toilet blocks. It is as effective or even more effective than an identical petroleum chemistry product, but it is without comparison in terms of toxicity and environmental protection.

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.

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.

Advantages of the Arcyvert toilet block

+ Triple enzymatic action: cleans, descales and shines
+ Deodorizes your toilets thanks to lavender essential oil
+ More than 6 weeks of guaranteed effectiveness with the 2 blocks
+ Microbiological treatment based on biodegradable enzymes
+ No toxicity: the intervention of enzymes is both active in decomposing and neutral because there is no harmful impact on the environment
+ Certified by Ecocert
+ Product not tested on animals
+ Product developed, made in France and packaged in a CAT near Rennes

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 (not supplied, see here)  then hang 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

The big advantage of enzymatic products is that they act precisely, in an almost "intelligent" way, on the target for which they were designed, a bit like a key that only fits in one lock. This advantage makes enzymes really respectful of the environment and also of our health. Ecological detergents have long focused on the life cycle of products and their ecological balance. But today, the consumer is alerted by the possible impact of ecological products on his health (such as respiratory and cutaneous allergies). Enzymes are neutral constituents for the body but their effectiveness is as high, or even more, than that of the ingredients at work in maintenance, such as solvents or surfactants.

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 Arcyvert

Founder 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.

Réponse de Penn'Ty Bio

Bonjour Do L,
Nous sommes vraiment désolés que ce produit ne corresponde pas à vos attentes. En effet, le bloc wc Arcyvert mousse peu (+/- en fonction de la dureté de l'eau) mais cela ne veut pas du tout dire qu'il n'est pas efficace pour nettoyer, détartrer et faire briller vos WC !
Quant au parfum, il n'y a pas de parfum de synthèse dans ce produit, uniquement des huiles essentielles, ce qui peut expliquer l'odeur moins forte (mais quand-même présente). Et encore une fois, une odeur très forte ne veut pas dire que les agents nettoyants sont efficaces ...
Bien cordialement.

Do L


Ça ne mousse pas ça ne sent rien ça ne fait rien!

Ch. D.


Je connaissais déjà ce produit. Je le recommande.


recharge bloc wc

Très bonne idée que de pouvoir ne racheter que la recharge et pas le bloc entier. Produit efficace et rapidité de livraison. Bravo à l'équipe !



C'est le meilleur que je connaisse !
