Sanitizer
Sanitizer
Sanitizer (/ˈsanɪtʌɪzər/), also known as a disinfectant, is a substance that is designed to kill or inactivate microorganisms such as bacteria, viruses, and fungi. The term is derived from the Latin word sanitas, meaning health, and the suffix -izer, which denotes an agent of action.
Types of Sanitizers
There are several types of sanitizers, including:
- Alcohol-based hand sanitizers: These sanitizers contain between 60% and 95% alcohol, which can kill many types of bacteria and viruses on contact.
- Non-alcohol-based hand sanitizers: These sanitizers use other chemicals, such as Benzalkonium chloride, to kill microorganisms.
- Surface sanitizers: These sanitizers are used to disinfect surfaces in environments such as homes, hospitals, and food preparation areas.
Usage
Sanitizers are used in a variety of settings, including healthcare, food service, and personal hygiene. They are often used when soap and water are not available for hand washing. The Centers for Disease Control and Prevention recommends using a hand sanitizer that contains at least 60% alcohol if soap and water are not available.
Safety and Effectiveness
While sanitizers can effectively kill many types of microorganisms, they are not effective against all types. For example, they are not typically effective against noroviruses or C. difficile spores. In addition, some bacteria have developed resistance to certain sanitizers.
Sanitizers can also cause skin irritation or dryness, especially with frequent use. It is important to use them as directed and to moisturize the skin regularly.
