Sanitizer

Sanitizer

A sanitizer is a substance, or a mixture of substances, that reduces the number of microorganisms on a surface or in a material to a safe level. Sanitizers are commonly used in healthcare settings, food production, and personal care to prevent the spread of infectious diseases.

Types of Sanitizers

There are several types of sanitizers, including:

• Alcohol-based hand sanitizers: These sanitizers contain 60-95% alcohol, typically in the form of ethanol, isopropanol, or n-propanol. They are effective against many bacteria and viruses, but not all types of microorganisms.

• Quaternary ammonium compounds: Also known as quats, these sanitizers are used in a variety of settings, including food service and healthcare. They are effective against a wide range of microorganisms.

• Peroxide-based sanitizers: These sanitizers use hydrogen peroxide or peracetic acid to kill microorganisms. They are often used in food production and healthcare settings.

• Chlorine-based sanitizers: These sanitizers use chlorine or hypochlorite to kill microorganisms. They are commonly used in water treatment and food production.

Effectiveness

The effectiveness of a sanitizer depends on several factors, including the type of microorganism, the concentration of the sanitizer, the contact time, and the presence of organic matter. Some sanitizers, such as alcohol-based hand sanitizers, are not effective against certain types of microorganisms, such as Clostridium difficile spores and norovirus.

Safety

While sanitizers are generally safe when used as directed, they can cause skin irritation or allergic reactions in some people. Ingestion or inhalation of sanitizers can also be harmful. It is important to use sanitizers properly and to store them out of reach of children.
