Glutaraldehyde hazard class and category

GHS hazard classes Glutaraldehyde falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 3 H301 GHS06
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06
Skin corrosion/irritation GHS chapter 3.2 Category 1A or 1B or 1C H314 GHS05

Hazardous to the aquatic environment - acute GHS chapter 4.1 Category 1 H400 GHS09
Hazardous to the aquatic environment - chronic GHS chapter 4.1 Category 2 H411 GHS09

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for Glutaraldehyde

Our own Glutaraldehyde safety data sheet walks through all sixteen sections of the published data. What it is not is the document an inspector asks for: an SDS is issued for a product by its supplier, so the sheet covering the grade actually standing in your store exists only in that supplier’s version. Collecting those and keeping them current as suppliers revise them is a separate job.

04 · Precautionary statements

Glutaraldehyde precautionary statements

CLP Annex VI assigns 16 precautionary statements to Glutaraldehyde. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

05 · Names in the regulation

Glutaraldehyde name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

07 · Health hazards

Glutaraldehyde health hazards and exposure limits

Glutaraldehyde hazard summary

Glutaraldehyde is a colorless, oily liquid with a sharp, pungent odor. Glutaraldehyde is used for industrial, laboratory, agricultural, medical, and some household purposes, primarily for disinfecting and sterilization of surfaces and equipment. For example, it is used in oil and gas recovery operations and pipelines, waste water treatment, x-ray processing, embalming fluid, leather tanning, paper industry, in fogging and cleaning of poultry houses, and as a chemical intermediate in the production of various materials. It may be used in select goods, such as paint and laundry detergent.

Glutaraldehyde carcinogenicity classification

Under the conditions of these 2-year inhalation studies, there was no evidence of carcinogenic activity of glutaraldehyde in male or female F344/N rats exposed to 250, 500, or 750 ppb. There was no evidence of carcinogenic activity in male or female B6C3F1 mice exposed to 62.5, 125, or 250 ppb.

Source: US National Toxicology Program · TR-490: Toxicology and Carcinogenesis Studies of Glutaraldehyde (CASRN 111-30-8) in F344/N Rats and B6C3F1 Mice (Inhalation Studies) (1999 )

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

Glutaraldehyde occupational exposure limits

US occupational exposure limits reported for Glutaraldehyde. PEL is enforceable (OSHA), REL is a recommendation (NIOSH), IDLH is the concentration at which escape becomes impossible without injury.
Limit Value Source
PEL none See Appendix G The National Institute for Occupational Safety and Health (NIOSH)
REL 0.2 ppm (0.8 mg/m³) Occupational Safety and Health Administration (OSHA)
REL C 0.2 ppm (0.8 mg/m3) See Appendix C (Aldehydes) The National Institute for Occupational Safety and Health (NIOSH)
IDLH N.D. The National Institute for Occupational Safety and Health (NIOSH)

These are United States values. The European Union sets its own indicative and binding limits, and the figure that applies at a given workplace is the one in the local regulation — not the one shown here.

10 · Handling and storage

Glutaraldehyde storage and handling

Glutaraldehyde reactive group

CAMEO Chemicals places Glutaraldehyde in the reactive groups Aldehydes, Polymerizable Compounds, Water and Aqueous Solutions. Compatibility with other chemicals is worked out from the group, not from the individual substance — which is why two substances you have never seen react can still be flagged as a pair that must be separated.

A reactive group is a CAMEO Chemicals (US NOAA) grouping, not a GHS hazard class: it has no code, no category and no legal force. It is what the storage compatibility matrix on this site computes from.

Glutaraldehyde safe storage

Store only in original container. Well closed. Separated from food and feedstuffs, incompatible materials and amines. Separated from strong oxidizers and strong bases. Keep in a well-ventilated room. Keep in the dark.

Source: ILO-WHO International Chemical Safety Cards (ICSCs)

Glutaraldehyde storage conditions

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature: -20 °C. Store under inert gas. Air sensitive.

Glutaraldehyde incompatible materials

11 · Questions

Glutaraldehyde — frequently asked questions

What is the CAS number of Glutaraldehyde?

The CAS number of Glutaraldehyde is 111-30-8. Its EC number is 203-856-5.

What is the chemical formula of Glutaraldehyde?

The molecular formula of Glutaraldehyde is C5H8O2 and its molecular weight is 100.12 g/mol.

What does a Glutaraldehyde label have to show?

Under CLP Annex VI the label for Glutaraldehyde carries the pictograms Skull and crossbones, Corrosion, Health hazard and Environment and the signal word is Danger.

Is Glutaraldehyde flammable?

CLP Annex VI assigns Glutaraldehyde no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it. The flash point reported for it is 95 °C (203 °F), above this value (ICSC).

Is Glutaraldehyde a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Glutaraldehyde. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.

What is the exposure limit for Glutaraldehyde?

The US occupational exposure limit reported for Glutaraldehyde is none See Appendix G (The National Institute for Occupational Safety and Health (NIOSH)). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.

What is the boiling point of Glutaraldehyde?

The boiling point reported for Glutaraldehyde is 100 °C (212 °F) (NIOSH).

What is the melting point of Glutaraldehyde?

The melting point reported for Glutaraldehyde is -14 °C (6.8 °F) (HSDB).

How should Glutaraldehyde be stored?
