Sanitisers
A
sanitiser is a chemical agent designed to reduce the population of microorganisms, such as bacteria and viruses, to safe levels. Unlike disinfectants, which aim to destroy all organisms on a surface, sanitisers focus on substantial reduction for public health and safety.
Types of Sanitisers
- Alcohol-Based (ABHS): Most common for personal hygiene. They typically contain 60% to 95% ethanol, isopropyl alcohol, or n-propanol. They work by denaturing proteins and disrupting the membranes of pathogens.
- Alcohol-Free: These often use active ingredients like benzalkonium chloride (BAC), chlorhexidine, or triclosan. They are generally less irritating and non-flammable but may be less effective against certain viruses compared to alcohol-based versions.
- Surface Sanitisers: Used in food processing or healthcare on hard surfaces. These may include chlorine-based compounds, quaternary ammonium compounds (“quats”), or peroxyacetic acid.
