Glutaraldehyde is a colorless, oily, liquid-chemical with a pungent odor. It is used for a number of applications such as the following:
- A cold sterilant in the health care industry
- A cross-linking and tanning agent
- A biocide in metalworking fluids and in oil and gas pipelines
- An antimicrobial in water-treatment systems
- A slimicide in paper manufacturing
- A preservative in cosmetics
- A disinfectant in animal housing
- A tissue fixative in histology and pathology labs
- A hardening agent in the development of X-rays
- In embalming solutions
- In the preparation of grafts and bioprostheses
- In various clinical applications
In the health care industry, glutaraldehyde is most often used to disinfect equipment that cannot be heat sterilized such as dialysis instruments, surgical instruments, suction bottles, bronchoscopes, endoscopes, and ear, nose, and throat instruments.
The chemical is most often used in a diluted form with solutions ranging from 0.1% to 50% glutaraldehyde in water. Trade names for glutaraldehyde-containing formulations include Cidex®, Sonacide®, Sporicidin®, Hospex®, Omnicide®, Metricide®, Rapicide® and Wavicide®.
Workers can be exposed to glutaraldehyde through inhalation or skin contact. Health effects that may occur as a result of exposure to glutaraldehyde include but are not limited to the following:
- Throat and lung irritation
- Asthma and difficulty breathing
- Contact and/or allergic dermatitis
- Nasal irritation
- Burning eyes and conjunctivitis
