Table 2.
Agent | Mechanism of Action | Benefits | Drawbacks | Adverse Effects | Reference |
---|---|---|---|---|---|
Ethanol (>60%) | Denaturation of proteins | Recommended by U.S. FDA against SARS-CoV-2; economical and easy to handle | Disagreeable odor, dryness of skin, possibility of unwanted toxicity in children | Skin: Itching, allergy, dermatitis Liver: Hypocalcemia, hypokalemia, hypomagnesemia, myoglobinuria Others: Vomiting, drowsiness, respiratory arrest, keto acidosis, arrhythmia, cardiac arrest |
[42,80,91] |
Isopropanol (>70%) | Denaturation of proteins | Recommended by U.S. FDA against SARS-CoV-2; economical and easy to handle | Unpleasant odor, dryness of skin, possibility of unwanted toxicity in children | Skin: Rash, itching, irritation, allergy Others: Myoglobinuria, gastritis, respiratory depression |
[42,80,91] |
Quaternary ammonium compounds | Enzymatic inactivation; Degradation of cellular proteins | Minimal human toxicity, better tolerability, no bad odor | Less effective in low pH and in the presence of organic substances | Mild irritation | [91,92] |
Hydrogen peroxide | Free-radical induced oxidation of cellular components | Relatively less toxic, inexpensive, easy to use | Corrosive | Mild irritation in skin and mucous membrane, vomiting, air embolism | [80,91,93] |
Iodine compounds | Degradation of cellular proteins, fatty acids, and nucleotides | Non-corrosive, ease of use | Unpleasant odor, staining, irritation | Rash, itching, local swelling | [91,92] |
Chlorine compounds | Halogenation/oxidation of cellular proteins | Effective in low concentration, low-cost | Corrosive, formation of toxic by-products, irritation | Nausea, coughing, shortness of breath, irritation of mucous membrane, stimulation of the upper airways | [91,94] |
