Biocides are chemical or biological agents used to combat harmful organisms such as bacteria, viruses, fungi, insects or rodents. They are used in many areas of everyday life, for example in disinfectants, wood preservatives or insecticides. The term “biocide” comes from the Greek and Latin: “bios” means life, “caedere” means to kill.

What are biocides used for?

Biocides play a crucial role in protecting health, hygiene and the preservation of materials.

Some important areas of application are:



• Hygiene and health protection: Disinfectants are used to eliminate pathogens on surfaces, in water or in the air and thus prevent infections.
• Material protection: Wood preservatives prevent the infestation of timber by fungi or insects and thus extend the service life of buildings and furniture.
• Pest control: The use of insecticides and rodenticides is an effective method of controlling pests such as insects and rodents. These animals can cause considerable damage to supplies or crops.
• Drinking & bathing water treatment: Biocides can be used to disinfect water to prevent the spread of pathogens.

How are biocides used?

The use of biocides can vary depending on the type of product or intended use. It is very important to always observe the instructions for use, safety regulations and hazard symbols. In this way, people and the environment can be protected.

General information on correct handling of biocides:



• Read the instructions for use: Read the labels and product information carefully before use to know the correct dosage and application method.
• Wear protective equipment: Depending on the product, it may be necessary to wear gloves, goggles or respiratory protection.
• Protect the environment: Many biocides should not be released into the environment. Residues and packaging must therefore be disposed of properly.
• Observe the regulations: In Switzerland, the Ordinance on Biocidal Products (OBP) regulates the use and placing on the market of biocidal products. Only approved and tested biocides may be used.

Authorization process for biocides:

Biocides can pose potential risks to human health and the environment and are therefore subject to strict testing and authorization procedures

In the EU and Switzerland, there are various regulations governing the handling of biocides:



• Evaluation of active substances: Before a biocide is approved, the active substance is subjected to a detailed scientific assessment. This examines efficacy, toxicity and possible environmental effects.
• Product-specific authorization: Manufacturers are obliged to apply for authorization for each product. This application must urgently demonstrate that the biocidal product meets the required safety and efficacy criteria.
• Labeling: Biocides must be labeled on the packaging in accordance with the applicable regulations. This serves to ensure that consumers receive all important information and information on risks.
• Regular monitoring: Even products that have already been approved are constantly monitored. This ensures that the biocides comply with the latest scientific findings and legal requirements.

Conclusion:

Biocides play an important role in protecting against harmful organisms and contribute to hygiene, health and material preservation. They help to prevent diseases and control pest infestations in various sectors such as agriculture, industry and healthcare.

Nevertheless, biocides can be harmful to the environment and health. Incorrect application or the use of unauthorized products can endanger water, soil and beneficial organisms. In addition, improper use can encourage the development of resistance and reduce the effectiveness of biocides. They should therefore be used responsibly and, whenever possible, more environmentally friendly alternatives should be considered.
