CPC effectively inactivates viruses with a lipid envelope6
El CPC effectively prevents infections in the upper respiratory tract caused by viruses with a lipid envelope.
Cetylpyridinium chloride-containing mouthwashes reduce in vitro SARS-CoV-2 infectivity
Here we show that Cetylpyridinium chloride (CPC), a quaternary ammonium compound present in many oral mouthwashes, reduces SARS-CoV-2 infectivity by inhibiting viral fusion with target cells.
We also found that CPC and CPC-containing mouth rinses decreased a thousand times the infectivity of SARS-CoV-2 in vitro, while the corresponding vehicles had no effect. CPC containing mouth rinses could represent a cost-effective measure to reduce SARS-CoV2 infectivity in saliva, aiding to reduce viral transmission from infected individuals.

What’s the difference between N95, KN95, FFP2 and KF94 mask rating?
The N95 mask has a full name of NIOSH-approved N95 respirator, which means these respirators are tested of 95% filtration and certified by the U.S. National Institute of Occupational Safety and Health (NIOSH).
And the KN95, FFP2 and KF94 mask is as effective as NIOSH-certified N95 mask with the same filtration efficiency, but are tested by different nation criteria. The KN95 respirator is a particulate-filtering mask tested using the China criteria.
The FFP2 is a filtering facepiece score of 94% filter capacity approved by Europe, and the KF94 is tested by Korea criteria.
To simply put, we could put these respirators into an equation as below:
-
N100 (99.97%) = FFP3 (99.95%)
-
N95 (95%) = KN95 (95%) = FFP2 (94%)
-
KF94 (94%)
-
KN90 (90%).
