what is in hand sanitizer that kills bacteria
Hand sanitizer Hand sanitizer that contains at least 60 percent alcohol or contains a "persistent antiseptic" should be used.[16][17] Alcohol rubs kill many different kinds of bacteria, including antibiotic resistant bacteria and TB bacteria. 90% alcohol rubs are highly flammable, but kill many kinds of viruses, including enveloped viruses such as the flu virus, the common cold virus, and HIV, though is notably ineffective against the rabies virus.[18][19][20]
Hand sanitizer Hand sanitizer is a liquid generally used to decrease infectious agents on the hands.[2] Formulations of the alcohol-based type are preferable to hand washing with soap and water in most situations in the healthcare setting.[3] It is generally more effective at killing microorganisms and better tolerated than soap and water.[4] Hand washing should still be carried out if contamination can be seen or following the use of the toilet.[5] The general use of non-alcohol based versions has no recommendations.[3] Outside the health care setting evidence to support the use of hand sanitizer over hand washing is poor.[6][7] They are available as liquids, gels, and foams.[4]
Hand sanitizer On April 30, 2015, the FDA announced that they were requesting more scientific data based on the safety of hand sanitizer. Emerging science also suggests that for at least some health care antiseptic active ingredients, systemic exposure (full body exposure as shown by detection of antiseptic ingredients in the blood or urine) is higher than previously thought, and existing data raise potential concerns about the effects of repeated daily human exposure to some antiseptic active ingredients. This would include hand antiseptic products containing alcohol and triclosan.[44]
Wastewater If the wastewater contains human feces, as is the case for sewage, then it may also contain pathogens of one of the four types:[2][3]
