Product Description:
Hand sanitizer is a product which may be in liquid, form or gel, or pressurized containers in a spray form or sometimes in form of foam generating product Hand Saitizers are generally used to decrease infectious agents on the surface of hands.[3][4] In most settings, hand washing with soap and water is generally preferred.[5][6][7] Hand sanitizer is less effective at killing certain kinds of germs, such as norovirus and Clostridium difficile and unlike soap and water, it cannot remove harmful chemicals.[5] Minimum contact time with antimicrobial agent in hand sanitizer is must therefore hand sanitizer is often incorrectly wiped off before its optimum contact time or it has dried,[5] and some are less effective because their alcohol concentrations are too low.[5]
In most healthcare settings alcohol-based hand sanitizers are preferable to hand washing with soap and water.[8][9] Reasons include it being better tolerated and more effective.[4] Hand washing with soap and water; however, should be carried out if contamination can be seen, or following the use of the toilet.[10] The general use of non-alcohol-based hand sanitizers has no recommendations.[8] Currently in the outbreak of SARS-COV-2 Virus outbreak Alcohol based hand sanitizers demand went up and duet to meet decontamination requirements water based hand sanitizer that contain minimum of 200 PPM available chlorine is recommended.[11]
Alcohol-based versions typically contain some combination of isopropyl alcohol, ethanol (ethyl alcohol), or n-propanol, with versions containing 60% to 75% alcohol the most effective. Optimum Alcohol concentration considered is 70% to 75% higher than that may render hand sanitizer less effective, and give just a dehydrating effect on microbial cell wall, presence of water molecule alcohol works as bactericidal [4] Care should be taken as they are flammable.[8] Alcohol-based hand sanitizer works against a wide variety of microorganisms but not spores.[4] Compounds such as glycerol may be added to prevent drying of the skin.[4] Some versions contain fragrances; however, these are discouraged due to the risk of allergic reactions.[12] Non-alcohol based versions typically contain benzalkonium chloride or triclosan; but are less effective than alcohol-based ones.
