Active ingredients : pure and natural enzymes

Active ingredients: natural enzymes

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

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

What are they used for ? Enzymes are found everywhere in nature: they are responsible for more than 5,000 reactions between molecules 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, bacteria in the intestine produce an enzyme, cellulase, which digests plant cellulose.

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

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

1 - A catalytic property : An enzyme accelerates a chemical reaction and is intact at the end of the reaction. The term biocatalyst is used to refer to the fact that an enzyme is manufactured by a living organism.

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

3 - A very rapid action. An enzymatic reaction lasts a thousandth of a second. One of the most efficient enzymes known to date in Nature, involved in the synthesis of the basic elements of DNA and RNA, allows this reaction to be accelerated, taking 18 milliseconds rather than 78 million years!

4 - A natural action : An action in the conditions of life on earth (of temperature, pressure, acidity, etc.), thus limiting the need for additional energy for the reaction to occur.Tablettes WC Arcyvert

What is so new about these enzyme-based products ?

First of all, they act in a completely different way. Conventional chemicals will act through a corrosive effect. By simply loosening the dirt so that it is carried away in the rinse water. More cleverly, enzymes destroy dirt by digesting and breaking it up. Cellulases, for example, destroy paper fibres, while lipases solubilise fats.

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


Instructions for use

Remove the ARCYVERT tablet from its packaging, tear open the bag and place the tablet directly into the toilet bowl. Leave to work for at least 30 minutes. Ideally, put the tablet in the evening so that it can work all night. Take the toilet brush and scrub with the water to obtain a good cleaning, to remove the tartar and to give a whiteness to the bottom of the bowl. Repeat the operation as soon as scale and/or dirt appears at the bottom of the bowl.

We answer your questions

▼ Are these toilet pads compatible with my micro-station that treats my wastewater (grey and black) ?
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 enzyme products is that they act precisely, almost "intelligently", on the target for which they have been designed, rather like a key that only fits in one lock. This advantage makes enzymes truly environmentally friendly and also friendly to our health. Ecological detergents have long focused on the life cycle of products and their ecological balance. But today, consumers are alerted to the possible impact of ecological products on their health (such as respiratory and skin allergies). Enzymes are neutral constituents for the body, but their efficiency is as high or higher than that of ingredients used in cleaning, such as solvents or surfactants.

Precautions for use

Caution. Causes skin irritation and severe eye irritation. In case of medical advice, keep container or label available. Keep out of reach of children. Wash hands thoroughly after use. Wear eye protection. In case of contact with eyes, rinse cautiously with water for several minutes. Remove contact lenses if present and easily removable. Continue rinsing. If eye irritation persists, consult a doctor. 

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

Logo Arcyvert

In 1979, the founder Daniel Mauban began designing cleaning products, first for septic tanks and then for sanitary facilities, based on environmentally friendly active principles. ARCYVERT was created as a precursor of an ecological offer for cleaning products. This was the start of the "septic tanks - drains" range, whose formulations remain unchanged to this day.

The range was then extended to household cleaning products, with the birth of organic shop networks in France. Working hand in hand with the organic circuit, the company has continued to grow by developing new products that are as close as possible to the needs of consumers, while remaining on a human scale.

Today the torch has been passed on to the next generation: Thierry Mauban perpetuates the values of the family company and the social commitment, in particular with the ESAT (Etablissement Spécialisé d'Aide au Travail), Les Ateliers de L'Espoir in Rennes, for the packaging.

Efficacité très relative

Détruit calcaire mais seulement à l’endroit où tablette se pose. Dommage

Godelle Chantal

Très bien.

Je les trouve très efficaces.



Détartre très bien, surtout quand on l'utilise avant un bon moment d'inactivité, pas besoin de frotter longtemps dans ce cas, cuvette impeccable !

Lila Rose

Au top !

J'ai réussi à récupérer le fond de la cuvette des wc de l'appart où je viens d'arriver !! J'y croyais pas au début mais j'en ai mis 1 galet 3 soirs de suite et miracle ! J'en mets maintenant 1 par semaine en entretien. Vraiment efficace.

Super !

Le produit détartre bien le fond des W.C. Envoi rapide et soigné. Je suis heureux :)
