In vitro and in vivo studies have shown that CPC has the ability to break down viruses with a lipid envelope, similar to the envelope that coronaviruses possess.

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.

  • Medical protective respirators: N95, FFP3

  • Public Protective face masks:  FFP2, KN95, 3PLY

  • Infrared thermometers

  • Nitrile & Latex gloves

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%).
