(64,852 posts)...sanitizers with active chlorine are even faster.
As I put in another post, it's a matter of 2 vs. 20 seconds. Exactly why is detail I won't bore people with by repeating.
CDC study (on their website) uses 1000 ppm as sodium hypochlorite as the standard. Tests were done for 30 seconds. Common sanitizing agents (with active chlorine), 70% ethanol or isopropanol, and common household surfactants were used. They all pretty much worked the same, but 30 seconds is quite a long duration compared to the actual mechanistic rates.
Alcohol also damages the lipid layer by simple solubility. Faster than detergent, slower than chlorine. The article misidentified the mechanism though by saying it's the same as with soap. That's incorrect.
Truth is, they all work, and although alcohol or active chlorine is faster, soap (better, detergents which are not soap) is a perfectly fine sanitizer for this.
At some point, it's a matter of preference. One is no better or worse than the others. Just different.
