ColdZyme Mouth Spray Can Deactivate Covid-19 By 98%
ColdZyme Mouth Spray, sprayed onto the mouth and throat could lower the risk of infection, and decrease the viral load locally. The lowered viral load may decrease viral shedding and thus minimise the spread of coronavirus, says the company, Enzymatica.
Enzymatica, claims its mouth spray ColdZyme can deactivate SARS-Cov-2 or COVID-19 by 98.3 per cent in just 20 minutes. The primary results of an in-vitro (lab test) study of the mouth spray have shown that ColdZyme acts as a protective barrier against COVID-19 and other viruses by deactivating it in “oral cavity”, the company has said.

The barrier solution of the device is mainly composed of glycerol and Atlantic cod trypsin. “The goal of the present study was to determine the ability of ColdZyme to deactivate SARS-CoV-2 known to cause the COVID-19 pandemic. A virucidal efficacy suspension test was conducted using ColdZyme against SARS-CoV-2. ColdZyme deactivated SARS-CoV-2 by 98.3% (1.76 log10) in 20 minutes,” the company added.
Furthermore, no cytotoxicity (the quality of being toxic to cells) was detected for ColdZyme at any dilution tested. The study — based on a standardised and validated methodology, i.e. ASTM International test method — was conducted by the US company Microbac Laboratories Inc – an independent, accredited and certified laboratory.
How does ColdZyme work?
SARS-CoV-2 actively replicates in the throat and shows high viral shedding also at a time of mild symptoms. “ColdZyme sprayed onto the mouth and throat could lower the risk of infection, and decrease the viral load locally. The lowered viral load may decrease viral shedding and thus minimise the spread of SARS-CoV-2,” the company claimed.
“Even if the current in vitro results cannot be directly translated into clinical efficacy, it is very interesting that ColdZyme is able to effectively deactivate SARS-CoV-2 in vitro since it constitutes a proof-of-principle that can be taken further into clinical studies,” said Claus Egstrand, Enzymatica’s Chief Operating Officer.
Egstrand said the results indicated that ColdZyme could offer a protective barrier against SARS-CoV-2. No company has claimed full-proof success in finding COVID-19 pandemic so far.
