NOVELTY - Durable graphene antiviral and antibacterial liquid comprises 3-8 pts. wt. graphene oxide, 10-15 pts. wt. antibacterial synergistic agent, 3.5-5 pts. wt. sodium dodecylbenzenesulfonate, 3-5 pts. wt. emulsifier, 1-3 pts. wt. glycerol, 1-3 pts. wt. propylene glycol and 80-100 pts. wt. water. USE - Used as durable graphene antiviral and antibacterial liquid. ADVANTAGE - The liquid causes bacterial cell death, blocks electron transfer between cytochrome b and cytochrome c1 thus inhibiting mitochondrial respiration, and makes mitochondria unable to supply the energy needed for normal metabolism of cells.
