Disinfectant solution - Tips and recommendations : Your online pharmacy selection

What is a disinfectant solution and how does it work?

A disinfectant solution is a chemical agent used to reduce or eliminate pathogenic micro-organisms on inert surfaces. Common active ingredients include ethyl alcohol, chlorine and quaternary ammonium compounds. These substances act by altering the structure of micro-organisms' proteins and nucleic acids, resulting in their death or inactivation. Used correctly, these solutions are effective in preventing the spread of infections, particularly in medical and public environments.

What are the differences between a disinfectant solution and an antiseptic?

Disinfectant solutions are primarily intended for use on surfaces and objects, while antiseptics are formulated for application to the skin or living tissue. Disinfectants generally have a higher concentration of active substances, making them unsuitable for direct application to the skin due to the risk of skin reactions or toxicity.

How do I choose the most appropriate disinfectant solution for my needs?

The choice of a disinfectant solution should be guided by several factors:

• Spectrum of activity: Opt for a product whose spectrum of activity meets your specific needs (bactericide, virucide, fungicide).
• Surface type: Some solutions are formulated for specific surfaces (medical, food, general).
• Safety and toxicity: Check compatibility with intended use, especially in sensitive environments such as hospitals or kitchens.
• Certifications and standards: Look for products that comply with local and international standards for proven effectiveness.

What precautions should I take when using disinfectant solutions?

It's crucial to use disinfectant solutions in strict accordance with the manufacturer's instructions to guarantee effectiveness while minimizing risks:

• Use of protective equipment: Wear gloves and, if necessary, protective goggles to avoid skin irritation or eye damage.
• Ventilation: Ensure good ventilation during application to avoid inhalation of potentially harmful vapours.
• Dosage and dilution: Follow dosage recommendations to maintain efficacy while reducing the risk of toxicity or property damage.

How to store and handle disinfectant solutions correctly to ensure their effectiveness?

Proper storage and handling are essential to maintain the effectiveness of disinfectant solutions:

• Storage: Keep products in a cool, dry place, away from direct sunlight and extremes of temperature, to avoid degradation of the active substances.
• Product stability: Respect expiration dates and replace any product whose appearance, odor or color has changed.
• Safety: Keep disinfectants out of the reach of children and pets to avoid accidents.

How effective are disinfectant solutions against viruses, particularly COVID-19?

Disinfectant solutions containing at least 70% alcohol, chlorine derivatives or quaternary ammoniums are effective against a broad spectrum of viruses, including coronaviruses such as COVID-19. These compounds work by destroying the lipid envelopes of viruses, neutralizing their ability to infect cells. For optimum efficacy, we recommend following the contact and dosage instructions provided by the manufacturer, and checking regulatory approvals for specific virucidal efficacy.

Can disinfectant solutions be used on electronic equipment?

The use of disinfectant solutions on electronic equipment requires caution and an appropriate choice of product. Low-concentration alcohol-based solutions (less than 70%) are often recommended, as they evaporate quickly and reduce the risk of moisture damage. It is essential to apply the disinfectant with a soft cloth without saturating the devices, avoiding openings such as sockets and ports to prevent internal damage.

How to assess the resistance of micro-organisms to disinfectants?

Micro-organism resistance to disinfectant solutions can develop with the improper and repeated use of insufficiently powerful or poorly applied products. To minimize this risk, it is crucial to vary the types of disinfectants used, and to respect recommended concentrations and contact times. Regular efficacy studies and microbiological testing can help identify the presence of resistant strains and adjust hygiene protocols accordingly.

What are the regulations governing the use of disinfectant solutions in healthcare establishments?

In healthcare establishments, the use of disinfectant solutions is strictly regulated to ensure the safety of patients and staff. Products must be approved by national health authorities and comply with international standards such as those of the World Health Organization (WHO) or the European Medicines Agency (EMA). These regulations guarantee the efficacy of the disinfectants used, and impose rigorous application protocols to avoid cross-contamination and nosocomial infections.

Are there effective natural alternatives to chemical disinfectants?

Although chemical disinfectant solutions are the most widely used for their proven efficacy, natural alternatives do exist, such as plant extracts containing essential oils. Substances such as thymol (derived from thyme) or eucalyptol (derived from eucalyptus) show antibacterial and antiviral properties. However, their spectrum of action may be more limited, and studies are often needed to validate their comparative efficacy and safety, especially in high-risk environments such as hospitals.
