„Biologisch“ klingt gut. Aber was bedeutet es konkret – und warum sollte es bei einem Rohrreiniger eine Rolle spielen? Dieser Artikel erklärt den echten Unterschied zwischen biologischen und chemischen Ansätzen beim Fett im Abfluss. Ohne Marketingsprache.
What chemical drain cleaners do – and what they don't
Most commercially available drain cleaners are based on sodium hydroxide (caustic soda) or strong acids. They are effective against hair and protein – both of which dissolve quickly in alkali. With fat, the situation is different.
Chemically, fat is an ester compound made of glycerin and fatty acids. Alkali breaks this bond – a process known as saponification. The result is soap, which is water-soluble and flows away. Sounds like a solution. But it isn't.
The problem: Saponification only works on the surface. The fat deeper in the pipe – in deposits, biofilm, pipe bends – is hardly reached by the alkali. What it does reach, it liquefies temporarily. This liquefied fat continues into the piping system – where, once the alkali is depleted, it settles again. Often even deeper and harder to reach than before.
In short: Chemical drain cleaners displace the problem. They do not solve it.
What biological treatment does
Biological products such as lipasanF® contain no aggressive chemicals. They contain lipase microorganisms – microorganisms that enzymatically break down fat. This process is called lipolysis.
During lipolysis, the bacteria produce the enzyme lipase. This enzyme splits triglycerides (the main component of dietary fat) into glycerin and free fatty acids. Both are water-soluble and are then metabolized by the bacteria as a food source. The fat disappears completely – it is not merely displaced.
And because the bacteria form a living colony that remains in the pipe: They continue to work, even when you do nothing. 24 hours a day, 7 days a week – as long as monthly refills are provided.
The decisive difference: One-time vs. permanent
| Criterion | Chemical | Biological (lipasanF®) |
|---|---|---|
| Duration of action | One-time, hours | Permanent, 24/7 |
| Fat breakdown | Saponification (surface level) | Lipolysis (complete) |
| Effect on biofilm | None | Breaks down biofilm |
| Pipe materials | Attacks seals | pH-neutral, gentle |
| Food grade | No | Yes |
| Odor reduction | Short-term | Permanent |
What applies to acute blockages
Biological treatment is not an emergency remedy. If the drain is acutely blocked, you must resolve it mechanically – plunger, drain auger, or in serious cases, a plumber. The same applies to chemical agents, by the way: even Drano often fails to clear a major blockage.
lipasanF® takes over afterwards: It prevents the blockage from recurring. That is the difference between treating symptoms and eliminating the cause.
Conclusion
Chemical drain cleaners are suitable for specific applications (hair removal, limescale removal). For grease in the drain, they are an emergency solution that allows the problem to recur. Biological treatment with lipasanF® is the only method that permanently breaks down grease – because it eliminates the cause, not the symptom.
