Denaturovaný ethanol - líh

wikipedia:
nejznámější ze skupiny alkoholů je ethanol, který je znám pro své hojné využití v průmyslu paliv (biopaliva), potravinářství (alkoholické nápoje), kosmetice a především v mnoha reakcích v organické syntéze

virus disinfection methods

Guideline for Disinfection and Sterilization in Healthcare Facilities (2008)


Methyl alcohol (methanol)
has the weakest bactericidal action of the alcohols and thus seldom is used in healthcare 488. The bactericidal activity of various concentrations of ethyl alcohol (ethanol) was examined against a variety of microorganisms in exposure periods ranging from 10 seconds to 1 hour ...


Ethyl alcohol,
at concentrations of 60%–80%, is a potent virucidal agent inactivating all of the lipophilic viruses (e.g., herpes, vaccinia, and influenza virus) and many hydrophilic viruses (e.g., adenovirus, enterovirus, rhinovirus, and rotaviruses but not hepatitis A virus (HAV) 58 or poliovirus) 49. Isopropyl alcohol is not active against the nonlipid enteroviruses but is fully active against the lipid viruses ...



Hydrogen Peroxide
Published reports ascribe good germicidal activity to hydrogen peroxide and attest to its bactericidal, virucidal, sporicidal, and fungicidal properties

Microbicidal Activity.  Hydrogen peroxide is active against a wide range of microorganisms, including bacteria, yeasts, fungi, viruses, and spores 78, 654. A 0.5% accelerated hydrogen peroxide demonstrated bactericidal and virucidal activity in 1 minute and mycobactericidal and fungicidal activity in 5 minutes 656. Bactericidal effectiveness and stability of hydrogen peroxide in urine has been demonstrated against a variety of health-care–associated pathogens; organisms with high cellular catalase activity (e.g., S. aureus, S. marcescens, and Proteus mirabilis) required 30–60 minutes of exposure to 0.6% hydrogen peroxide for a 108 reduction in cell counts, whereas organisms with lower catalase activity (e.g., E. coli, Streptococcus species, and Pseudomonas species) required only 15 minutes’ exposure 657...



Peracetic Acid and Hydrogen Peroxide
Two chemical sterilants are available that contain peracetic acid plus hydrogen peroxide (i.e., 0.08% peracetic acid plus 1.0% hydrogen peroxide [no longer marketed]; and 0.23% peracetic acid plus 7.35% hydrogen peroxide

How do disinfectants kill viruses?

So how do our viruses react to pasteurization, chlorine disinfection and UV radiation?

“A virus is a genome and some proteins. We discovered that each disinfectant has totally different effects, attacking one or several of the virus’ functions.

Coronavirus can persist in air for hours and on surfaces for days
  
Viruses were applied to copper, cardboard, stainless steel, and plastic maintained at 21 to 23°C and 40% relative humidity over 7 days

On plastic and stainless steel than on copper and cardboard, and viable virus was detected up to 72 hours after application

SARS-CoV-2 remained viable in aerosols throughout the duration of our experiment (3 hours), with a reduction in infectious titer from 103.5 to 102.7 TCID50 per liter of air
