Effect of Di-N-decyl dimethyl ammonium chloride (DNC) on SARS-CoV-2 inactivation.

Concentration (mg/L)	Log10 reduction in infectious SARS-CoV-2 titer achieved Mean (Min ~ Max)
	0.5 min	1 min	5 min	10 min
170	2.50 (2.25*2.75)	≥ 4.92a	≥ 4.92	≥ 4.92
212	3.59 (3.50–3.75)	≥ 4.92	≥ 4.92	≥ 4.92
283	≥ 4.92	≥ 4.92	≥ 4.92	≥ 4.92
425	≥ 4.92	≥ 4.92	≥ 4.92	≥ 4.92
850	≥ 4.92	≥ 4.92	≥ 4.92	≥ 4.92

^aThe value of ≥ 4.92 means that no live virus is observed after the treatment, while the smaller values indicate that a different amount of virus survives after the treatment.
