Disinfectant

Disinfectants are a type of chemical used to eliminate bacteria and other microorganisms.

Usage
Naked Snake carried several disinfectants in his field medical kit during his missions into the Virtuous Mission and Operation Snake Eater. In the former mission, he was forced to use it during the mission's conclusion after he sustained injuries during his encounter with The Boss at Dolinovodno's bridge, including lacerations to his upper arms, right elbow, and abdomen. GRU Spetsnaz soldiers also carried these on hand at Tselinoyarsk.

Disinfectants were also carried in large variants of the medical kits used by the personnel on the San Hieronymo Peninsula.

Behind the scenes
The Disinfectant is a healing item used for the Survival Viewer in Metal Gear Solid 3: Snake Eater. The name is technically inaccurate as "disinfectants" are chemicals used to eliminate bacteria and other microorganisms on non-organic surfaces. A more accurate term for it would be "anti-septic." They are limited at the start of the game, but the player can gain more of them either ready-made in certain locations, or by procuring some silk horehounds, identifiable as tall bushy shrubs with white flowers on it.
