As an essential part of corporate hygiene, companies must consider what types of disinfectants are suitable for their needs, and the various disinfection methods to be used depending on the area of application. Understanding the clear differences between the meaning of disinfection, cleaning and sterilisation helps companies select the most suitable method for their needs, enabling the effective combating of pathogens, minimisation of risks, and maintaining of hygiene standards.

Cleaning, disinfection and sterilisation: their importance for businesses
In companies and public facilities, disinfection is a key component of health protection and regulatory compliance. It ensures that pathogens and unwanted microorganisms are effectively killed or inactivated, protecting employees, customers, and visitors from infection.
It’s important to understand the difference between cleaning, disinfection and sterilization. While cleaning (for example, hand washing) removes visible dirt, the meaning of disinfection is to reduce the number of microorganisms to minimise infection risks. Sterilisation goes one step further and achieves complete germ elimination. Sterilisation is mainly used in healthcare and laboratory environments where maximum hygiene standards are required.
What types of disinfectants are there?
Chemical disinfectants use different active ingredients to eliminate microorganisms on skin, surfaces, or equipment:
- Alcohol-based disinfectants (e.g., ethanol or isopropanol) are particularly skin-friendly. They act quickly against bacteria, enveloped viruses, and fungi and are standard for hand disinfection.
- Aldehydes (e.g., formaldehyde, glutaraldehyde) have a broad spectrum of activity, including spores, and are used mainly for instrument and surface disinfection due to their potential skin irritation.
- Chlorine compounds (e.g., sodium hypochlorite) are fast and cost-effective, suitable primarily for surface disinfection and water treatment.
- Peroxides (e.g., hydrogen peroxide, peracetic acid) are eco-friendly oxidising agents with broad efficacy, increasingly used for surface disinfection.
Fitness centres often use alcohol-based surface disinfectants for equipment, whereas the food industry prefers chlorine-based solutions to prevent residues, while care facilities often rely on aldehyde-free products to protect sensitive respiratory systems.
Disinfectants must be certified and approved for their intended use, e.g. through compliance with EN standards in the EU, BS EN standards in the UK, or EPA registration in the United States. In healthcare and laboratory settings, listings by recognised institutions such as the European Chemicals Agency (ECHA) or the Centers for Disease Control and Prevention (CDC) may also apply. The optimal disinfectant should be selected based on required contact time, material compatibility, and user safety.
Physical disinfection methods: procedures and applications
In addition to chemical products, there are also physical methods of disinfection:
- Thermal Disinfection uses heat, hot air or steam, and is standard in the reprocessing of medical instruments or cleaning systems.
- UV-C-Light uses shortwave radiation to destroy microorganisms and is increasingly used for air and surface disinfection.
- Filtration mechanically removes microorganisms, for example in water systems, and is widely used in the food industry.
Physical methods are residue-free and environmentally sustainable but have limitations with shadowed areas or heat-sensitive materials.
Combined and specialised disinfection techniques
Combined and specialised techniques enhance disinfection performance by combining chemical and physical principles. In highly sensitive areas such as cleanrooms, specialised laboratories, or medical environments, these methods achieve the level of microbial control that conventional techniques alone cannot. A combined or specialised technique is also effective for hard-to-reach areas, where conventional cleaning reaches its limits.
Modern systems such as ozone disinfection use ozone gas, a powerful oxidising agent that destroys microorganisms within minutes and reaches every corner without leaving chemical residues. Equally effective and environmentally friendly is hydrogen peroxide fogging, which creates a fine aerosol cloud that disinfects entire rooms and equipment evenly.
Both ozone disinfection and hydrogen peroxide fogging are particularly suited to room and surface disinfection in areas with high hygiene requirements.
The many application areas of disinfection in companies
Different workplace environments, such as companies, public institutions or sensitive industries require tailored disinfection methods. In offices, schools, and administrative buildings, alcohol-based hand disinfectants are standard, complemented by surface disinfection using chlorine or peroxide-based products. These ensure quick and reliable pathogen reduction on frequently touched surfaces, reducing infection risk.
In gastronomy and food production, HACCP-compliant cleaning and disinfection plans are essential, not only for employee health but especially for food safety. Large kitchens, butcheries, and processing plants often rely on EN norms (Europe), ISO 22000 (International) listed disinfectants approved for food contact, offering broad-spectrum efficacy.
In healthcare and care facilities, disinfection is applied according to risk categories: hand, surface, and instrument disinfection, as well as thermal methods, are indispensable. Strict standards must be observed to protect patients, staff, and visitors from infection.
In modern office environments, preventive hygiene is gaining importance. Many organisations install touchless dispensers at entrances, coffee stations, and meeting rooms, significantly reducing infection rates and sick leave.
Legal requirements and certifications for disinfectant use
Clear legal frameworks are fundamental to ensuring hygiene compliance and protecting public health. Regulations such as the EU Food Hygiene Regulation (EC) No 852/2004, the UK Food Safety and Hygiene Regulations, and international HACCP guidelines define proper disinfection practices for food-related environments. Products must be officially approved, validated for efficacy, and comply with recognised testing benchmarks such as EN standards or EPA registration to guarantee safe and effective use.
For businesses, this means: disinfection measures must be appropriate, documented, and traceable. Proper documentation simplifies audits and certifications and builds trust among employees, customers, and partners, ensuring compliance and hygiene across the board.
The right disinfectant for every need
Disinfection is a fundamental protective measure in all hygiene-sensitive sectors. Whether chemical or physical, the right method depends on the objective, material compatibility, and infection risks. Companies should view disinfection as an integral part of their hygiene strategy and comply with industry-specific standards. This not only safeguards health but also ensures regulatory and quality compliance.
