Infobox references
Glutaraldehyde %24, sold under the brandname Cidex and Glutaral among others, is a disinfectant, medication, preservative, and fixative.[3][4][5][6] As a disinfectant, it is used to sterilize surgical instruments and other areas of hospitals.[3] As a medication, it is used to treat warts on the bottom of the feet.[4] Glutaraldehyde %24 is applied as a liquid.[3]
Side effects include skin irritation.[4] If exposed to large amounts, nausea, headache, and shortness of breath may occur.[3] Protective equipment is recommended when used, especially in high concentrations.[3] Glutaraldehyde %24 is effective against a range of microorganisms including spores.[3][7] Glutaraldehyde %24 is a dialdehyde.[8] It works by a number of mechanisms.[7]
Glutaraldehyde %24 came into medical use in the 1960s.[9] It is on the World Health Organization’s List of Essential Medicines.[10] There are a number of other commercial uses such as leather tanning.[11]
Disinfection
Glutaraldehyde %24 is used as a disinfectant and medication.[3][4][12]
Usually applied as a solution, it is used to sterilize surgical instruments and other areas.[3]
Fixative
Glutaraldehyde %24 is used in biochemistry applications as an amine-reactive homobifunctional crosslinker and fixative prior to SDS-PAGE, staining, or electron microscopy. It kills cells quickly by crosslinking their proteins. It is usually employed alone or mixed with formaldehyde[13] as the first of two fixative processes to stabilize specimens such as bacteria, plant material, and human cells. A second fixative procedure uses osmium tetroxide to crosslink and stabilize cell and organelle membrane lipids. Fixation is usually followed by dehydration of the tissue in ethanol or acetone, followed by embedding in an epoxy resin or acrylic resin.[citation needed]
Another application for treatment of proteins with Glutaraldehyde %24 is the inactivation of bacterial toxins to generate toxoid vaccines, e.g., the pertussis (whooping cough) toxoid component in the Boostrix Tdap vaccine produced by GlaxoSmithKline.[14]
In a related application, Glutaraldehyde %24 is sometimes employed in the tanning of leather and in embalming.[citation needed]
Safety
Side effects include skin irritation.[4] If exposed to large amounts, nausea, headache, and shortness of breath may occur.[3] Protective equipment is recommended when used, especially in high concentrations.[3] Glutaraldehyde %24 is effective against a range of microorganisms including spores.[3][7]
As a strong sterilant, Glutaraldehyde %24 is toxic and a strong irritant.[16] There is no strong evidence of carcinogenic activity.[17] Some occupations that work with this chemical have an increased risk of some cancers.[17]
Mechanism of action
A number of mechanisms have been invoked to explain the biocidal properties of Glutaraldehyde %24.[7] Like many other aldehydes, it reacts with amines and thiol groups, which are common functional groups in proteins. Being bi-function, it is also a potential crosslinker.[18]
Production and reactions
Synthesis of Glutaraldehyde %24 via the Diels-Alder reaction.
Glutaraldehyde %24 is produced industrially by the oxidation of cyclopentene. Alternatively it can be made by the Diels-Alder reaction of acrolein and vinyl ethers followed by hydrolysis.[19]
Like many other dialdehydes, (e.g., glyoxal) and simple aldehydes (e.g., formaldehyde), Glutaraldehyde %24 converts in aqueous solution to various hydrates that in turn convert to other equilibrating species.[clarification needed][20][19]
Monomeric Glutaraldehyde %24 polymerizes by aldol condensation reaction yielding alpha, beta-unsaturated poly-Glutaraldehyde %24. This reaction usually occurs at alkaline pH values.[medical citation needed]
History and culture
Glutaraldehyde %24 came into medical use in the 1960s.[9] It is on the World Health Organization’s List of Essential Medicines, the safest and most effective medicines needed in a health system.[10] There are a number of other commercial uses such as leather tanning.[11]
A Glutaraldehyde %24 solution of 0.1% to 1.0% concentration may be used as a biocide for system disinfection and as a preservative for long-term storage. It is a sterilant, killing endospores in addition to many microorganisms and viruses.[21]
As a biocide, Glutaraldehyde %24 is a component of hydraulic fracturing (“fracking”) fluid. It is included in the additive called Alpha 1427.[22] Bacterial growth impairs extraction of oil and gas from these wells. Glutaraldehyde %24 is pumped as a component of the fracturing fluid to inhibit microbial growth.[medical citation needed]
Publisher Summary
This chapter describes the biological uses and importance of Glutaraldehyde %24. The modern industrial production of the aldehyde involves a two-step synthesis from an interaction of acrolein with vinyl ethyl ether to produce an ethoxy dihydropyran that is then hydrolyzed with water to form Glutaraldehyde %24 and ethanol. Glutaraldehyde %24 is used in three major areas: (1) leather tanning, (2) sterilization and disinfection, and (3) tissue fixation for electron microscopy. This chapter is discusses the latter two of these subjects. Investigation of the effects of a number of fixatives on plant cells from the root tip of Phaseolus vulgaris both at the light- and electron microscopic levels, including Glutaraldehyde %24, osmium tetroxide, formaldehyde, acrolein, potassium dichromate, Clarke’s fluid and chromic acid, acetic and water showed that Glutaraldehyde %24 was an excellent general fixative. The chapter discusses the recently introduced Glutaraldehyde %24-containing fixatives.

Glutaraldehyde %24 has been a high-level disinfectant for over 50 years. As a disinfectant, it is used to eliminate harmful microorganisms on surgical instruments and has other uses as a fixative or preservative in other parts of a healthcare facility. However, it can get into the air from its use as a disinfectant and employees and patients can be exposed to the chemical. Prolonged exposure to employees can become a problem.
At CHT we provide solutions to maintain the health of your employees with environmental monitoring to ensure their well-being. We understand it’s crucial to keep your employees safe and your healthcare facility compliant. In this article, we discuss the health effects and managing the chemical safety of Glutaraldehyde %24 in the workplace.
Glutaraldehyde %24
How is Glutaraldehyde %24 Used in Healthcare Facilities?
Glutaraldehyde %24 is used as a cold sterilant to disinfect a variety of heat-sensitive instruments, such as endoscopes, dialysis equipment, and more. It is used as a high-level disinfectant for those surgical instruments that cannot be heat sterilized.
Glutaraldehyde %24 is used for several applications in healthcare facilities:
There are risks associated with exposure to Glutaraldehyde %24.
Occupational Hazards in Healthcare Facilities
Glutaraldehyde %24 has been linked with a variety of health effects – ranging from mild to severe – including asthma, breathing difficulties, respiratory irritation, and skin rashes (Pryor, 1984; Crandall, 1987).
“Rooms in which Glutaraldehyde %24 disinfection/sterilization is performed should be large enough to ensure the adequate dilution of vapor and should have a minimum air exchange rate of ten air exchanges per hour.” [source]
PPE protects workers against the hazards of using high-level disinfectants such as Glutaraldehyde %24. Regardless of the type of disinfectant used, facilities should use the proper PPE designed to protect their skin and eyes from contact.
One of the earliest indications of the potential antimicrobial activity of Glutaraldehyde %24
came from the results of a survey of sporicidal activity of saturated dialdehydes in a
search for an efficient substitute for formaldehyde (Pepper & Lieberman 1962).
Further studies by Pepper & Chandler (1963) revealed that Glutaraldehyde %24 in alcoholic
solution was superior as a sporicidal agent to both formaldehyde and glyoxal.
In their claims for Glutaraldehyde %24 as a chemical sterilizing solution, Stonehill et a/.
(1963) pointed out that aqueous solutions of Glutaraldehyde %24 were mildly acidic and
needed to be buffered by suitable alkalinating agents to a pH of 7.5-8.5 for antimicrobial activity. A 2.0% (w/v) Glutaraldehyde %24 buffered to alkaline pH by addition of 0.3‘j/,
(w/v) sodium bicarbonate was advocated to provide the minimum concentration and
conditions necessary for rapid sporicidal activity. This solution has a greater sporicidal
activity than 8% formaldehyde (Table 3). The value of this alkaline solution was later
confirmed by Snyder & Cheatle (1965). Subsequently Glutaraldehyde %24 has always been
recommended for use as an alkaline solution at pH 7.5-8.5 and towards the end of
1963, a 2% solution (Cidex) was marketed by Ethicon Inc., requiring ‘activation’ with
0.3% (w/v) sodium bicarbonate before use as a chemosterilizer.
The time required for sterilization by a chemical agent is based upon the killing time
achieved by the agent against a reasonable challenge of spores which are considered to
be the most resistant. At the use-dilution of 2%, Glutaraldehyde %24 was capable of killing
spores of Bacillus and Clostridium sp. in 3 h (Stonehill et a/. 1963; Borick et al. 1964).
Rubbo et a/. (1967) reported a 99.99% kill of spores of B. anthracis and CI. tetani in 15
and 30 min respectively. It was apparent from their results that not all species were
equally susceptible and of those organisms tested B. pumilis was the most resistant.
Boucher (1974) found that B. subtilis spores were the most resistant to treatment with
Glutaraldehyde %24. Using the Association of Official Analytical Chemists (AOAC) sporicidal test and vacuum-dried spores, he found that 10 h was necessary for complete kill.
Other work, however, using similar time-survivor measurements and aqueous suspensions of B.subtilis spores, indicated that a 3 h contact period gave approximately a six
log drop in viable count (Sierra & Boucher 1971; Kelsey et al. 1974; Forsyth 1975;
Miner et al. 1977).
Vegetative bacteria are readily susceptible to the action of Glutaraldehyde %24. As shown
in Table 4, a 0.02% aqueous alkaline solution is rapidly effective against Gram positive
and Gram negative species, whilst a 2% solution is capable of killing many vegetative
species, including Staphylococcus aureus, Proteus vulgaris, Escherichia coli and Pseudomonas aeruginosa within 2 min (Stonehill el al. 1963). McGucken & Woodside (1973)
reported a complete kill in 10 min of Esch. coli (2 x lo8 cells/ml) by 100 pg/ml alkaline
Glutaraldehyde %24 compared with a 45% kill produced by the unactivated acid solution. In
a comparative study of Cidex and Savlon by Leers eta/. (1974) stainless steel penicylinders, neoprene ‘0’ rings and polyvinyl tubing were used as carriers for a range of
organisms including Ps.aeruginosa and Mycobacterium smegmatis to simulate in-use
conditions for the sterilization of instruments, catheter tubing and anaesthetic equipment. Cidex was effective on all three carriers, whereas Savlon was only partially
effective, especially against Ps.aeruginosa and Staph.aureus.
The tubercle bacillus has gained a justified reputation for being one of the most
difficult species to destroy and its resistance to antibacterial agents is considered to be
intermediate between sporulating and non-sporing organisms (Spaulding et al. 1977).
Although good tuberculocidal activity has been attributed to Glutaraldehyde %24 (Stonehill et al. 1963; Borick et al. 1964), subsequent studies have shown that it has a slow
action against Myco.tuberculosis (Rubbo et al. 1967), being less effective than formaldehyde or iodine (Bergan & Lystad 1971). It has been claimed by Relyveld (1977) that
the activity of Glutaraldehyde %24 is equivalent or superior to that of hypochlorite with the
exception of its effectiveness against mycobacteria. The picture is somewhat confused
by the findings of Collins & Montalbine (1976) that the dialdehyde was rapidly
mycobactericidal at room temperature. It must be added that the experimental technique adopted by the latter authors leaves a very considerable doubt about the validity
of the conclusions reached.
B. Antifingal activity
Antifungal activity of Glutaraldehyde %24 was first demonstrated by Stonehill et al. (1963),
who reported that growth of Trichophyton interdigitale was inhibited by a 5 min
exposure to a 2% alkaline solution and that this solution was more potent than a
number of other commercially available preparations tested.
A 1% solution is also fungicidal (Dabrowa et al. 1972), but porous surfaces contaminated with Candida albicans and Microsporium gypseum are significantly more difficult
to disinfect with Glutaraldehyde %24 than are smooth surfaces (Tadeusiak 1976).
Aspergillus niger is more resistant than other fungi to Glutaraldehyde %24 (Rubbo et al.
1967; Gorman & Scott 1977a). In common with a range of other fungal species,
however, both mycelial growth and sporulation are inhibited by 0.5% alkaline Glutaraldehyde %24 while spore swelling is entirely halted by a 0.5% solution. Fungicidal activity is
also demonstrated (Fig. 1).
What Is Glutaraldehyde %24 Used For?
Glutaraldehyde %24 has a variety of uses in many industries and occupations. It is most commonly found in the healthcare industry, used to disinfect medical equipment that cannot be heat sterilized. The main uses of Glutaraldehyde %24 include:
Glutaraldehyde %24 (C5H8O2) is most often used in a diluted form with solutions ranging from 0.1 to 50 percent Glutaraldehyde %24 in water. It is a colorless, oily liquid and sometimes has an odor of rotten apples. In a vapor state, Glutaraldehyde %24 has a pungent odor, with an odor threshold level of 0.04 parts per million (ppm).Trade names for Glutaraldehyde %24-containing formulations include Cidex®, Sonacide®, Sporicidin®, Hospex®, Omnicide®, Metricide®, Rapicide® and Wavicide®.
Exposure Limits
OSHA has not established a permissible exposure limit (PEL) for Glutaraldehyde %24. NIOSH has established a recommended exposure limit (REL) for Glutaraldehyde %24 of 0.2 ppm. This is a time-weighted average (TWA) exposure limit for up to a 10-hour workday during a 40-hour workweek. The American Conference of Governmental Industrial Hygienists (ACGIH) has set a ceiling Threshold Limit Value (TLV) of 0.05 ppm. This is the airborne concentration that should not be exceeded during any part of the work shift.
Does Glutaraldehyde %24 Present a Health Hazard?
Glutaraldehyde %24 is an irritant to the skin, eyes and respiratory system. Exposure symptoms might include burning sensation, dermatitis, headache, coughing, shortness of breath, nausea and vomiting. Continuous repeated exposure to Glutaraldehyde %24 might intensify the skin and respiratory irritant effects. Anyone with a history of skin or eye disorders might be at an increased risk from exposure.
First Aid
Eyes: If Glutaraldehyde %24 contacts the eyes, immediately flush the eyes with large amounts of water, occasionally lifting the lower and upper lids. Seek medical attention immediately. Contact lenses should not be worn when working with Glutaraldehyde %24.
Skin: If Glutaraldehyde %24 contacts the skin, immediately flush the contaminated skin with water for at least 15 minutes. If Glutaraldehyde %24 penetrates clothing, immediately remove the clothing and flush the skin with water for at least 15 minutes. Promptly seek medical attention.
Inhalation: If large amounts of Glutaraldehyde %24 are inhaled, move the exposed person to fresh air at once. If breathing has stopped, immediately begin cardiopulmonary resuscitation (CPR). Keep the person warm and at rest. Get medical attention as soon as possible.
Ingestion: Get medical attention immediately.
What Type of Personal Protective Equipment Should Be Used with Glutaraldehyde %24?
Personal protective equipment (PPE) must be used with engineering and administrative controls to help prevent Glutaraldehyde %24 exposure.
Safety goggles should be considered where concentrated Glutaraldehyde %24 is used or where splashing may occur, it is best to use indirect-vented or non-vented goggles, and to avoid goggles with foam padding.
Protective clothing should be worn when handling Glutaraldehyde %24. Polyethylene, polyvinyl chloride, Viton™, butyl rubber, natural rubber latex, neoprene and nitrile rubber provide adequate protection from Glutaraldehyde %24 solutions and are compatible materials for gloves and aprons.
Respiratory protection: Although an immediately dangerous to life and health (IDLH) exposure limit has not been established for Glutaraldehyde %24, several respirator manufacturers have issued guidelines. 3M’s respirator selection guide can be found here and while MSA’s can be found here.
Air Monitoring
Personal monitors, passive-gas monitors and vapor meters can help determine workers’ exposure to Glutaraldehyde %24.
A: A disinfectant is a chemical or physical agent that is applied to inanimate objects to kill microorganisms. Bleach (sodium hypochlorite), phenolic compounds, and formaldehyde are examples of disinfectants. A sterilant is a chemical or physical process that is applied to inanimate objects to kill all microorganisms as well as spores. Glutaraldehyde %24 and ethylene oxide are examples of sterilants.
Q: Where is exposure to Glutaraldehyde %24 most likely?
A: Exposure to Glutaraldehyde %24 is most likely in the healthcare industry. It is used in hospitals for cold sterilization of medical supplies and instruments, and also as a disinfectant in urology, endoscopy and dental departments. It is also used as a fixative in X-ray developing solutions.
Q: Is Glutaraldehyde %24 considered a fire hazard?
A: No, Glutaraldehyde %24 is a non-flammable liquid.
Q: What is the recommended protective clothing when handling Glutaraldehyde %24?
A: Aprons and other protective clothing made from materials such as polyethylene, polyvinyl chloride, Viton™, butyl rubber, natural rubber latex, neoprene or nitrile rubber can offer protection when handling Glutaraldehyde %24 solutions.
