ViruBLOC Nasal Microgel Spray

The nasal cavity represents a potential site of transmission and replication of the SARS-CoV-2 virus in the initial stage of COVID-19. SARS-CoV-2 is an enveloped virus of the Coronaviridae family. Its outer envelope (pericapsid) consists of a phospholipid bilayer membrane.

ViruBLOC Nasal Microgel is composed of 3 main ingredients: glycerol, hydroxypropyl methylcellulose, and Nicomenthyl® (menthyl nicotinate, a vitamin B3 derivative), acting in synergy to create an efficient triple action of chemical-physical and mechanical nature:

  1. TRAP: glycerol and hydroxypropyl methylcellulose create a transient and osmotically-active mucoadhesive barrier, which traps the viruses.
  2. DEACTIVATE: the lipid/amphiphilic structure (i.e., having both hydrophobic and hydrophilic character) of Nicomenthyl® interferes with the viruses’ pericapsids (also of lipid and amphiphilic nature), disrupting their conformation and preventing them from penetrating and infecting the cells.
  3. PROTECT: the barrier of ViruBLOC Nasal Microgel protects the nasal cavity, stimulating mucous secretion (one of its most important natural defenses) and helping to remove the deactivated virus (towards the stomac or blowing the nose).
