Glutaraldehyde

Also called: glut, cold sterile, high-level disinfectant

A strong liquid sterilant and high-level disinfectant for heat-sensitive items.

Glutaraldehyde (2% or stronger) can sterilize with very long soaks, or high-level disinfect (kill everything except large numbers of spores) in a shorter time. CDC lists 20 minutes at room temperature as the minimum for high-level disinfection; your product label may require longer. Because it is toxic and slow, CDC discourages using heat-sensitive items that need it, since heat-tolerant or disposable versions exist for most dental items.

How to spot it

  • A jug of solution with an activator, and a covered soaking tray with a date label.

What it is used for

  • Only for heat-sensitive semicritical items (they touch mucous membranes) that cannot be heat-sterilized, exactly as the label directs.
  • Rinse items well afterward; items soaked this way are not sterile once stored.

Safety and care

  • Irritates skin, eyes and lungs and can cause allergies; use closed containers and good ventilation.
  • Regular exam gloves are not a good barrier; wear chemical-resistant gloves and an apron, goggles and a face shield.
  • Never use it as a surface disinfectant or holding solution.
