I need a freelancer search for information about antimicrobial activity (efficacy and contact time) against bacteria and virus, included COVID19, for the following compounds:
- Benzethonium Chloride
- Benzalkonium Chloride
- Chlorhexidine Gluconate
The freelancer should provide scientific articles to support the information. I need information about which micro-organism the products above are active against and the necessary contact time.
