Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures

Skin Contact:

Remove contaminated clothing.

In case of burns immediately wash area with water for 10-15 minutes.

Wash affected area with plenty of polyethylene glycol.

Eye contact:

In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice.


Remove patient to fresh air. Apply artificial respiration only if patient is not breathing.


Have patient rinse mouth thoroughly with water.

If swallowed, do not induce vomiting: seek medical advice immediately and show this container or label.

General Advice:

NOTE TO PHYSICIANS: Treat by observation and supportive measures as indicated by the patients conditions.

Fire-fighting measures

Suitable Extinguishing Media:

In case of fire use water spray or fog, alcohol resistant foam, dry chemical or carbon dioxide.

Do not use water jets.


Toxic and irritant fumes may be formed.

Decomposition products may include carbon monoxide and carbon dioxide.

Fire Fighting Equipment/Instructions:

Not flammable but will support combustion.

High concentration of airborne dust may form explosive mixture with air. Ensure that good housekeeping practices are followed as well as applicable guidelines such as the National Fire Protection Association (NFPA) 654, "Prevention of Fire Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids".

Vapours may be heavier than air and may travel along the ground to some distant source of ignition and flash back.

Keep container(s) exposed to fire cool, by spraying with water.

Wear Chemical Protection Suit and Positive-Pressure Breathing Apparatus.

Accidental release measures

Environmental Precautions:

Avoid raising dust.

If contamination of drainage systems or water courses is unavoidable, immediately inform appropriate authorities.

Personal Precautions:

Do not breath vapours, ensure adequate ventilation and keep away from spillage or leak.

Eliminate all sources of ignitions.

Wear suitable protective clothing.

Methods for Cleaning Up:

Shut off all ignition sources.

Shut off source of leak if safe to do so.

Contain spillage by using sand, earth or any other appropriate absorbent barriers.

Sweep or shovel-up spillage and remove contaminated material to a safe location.

Do not flush away residues with water.

Handling and storage


The usual precautions for handling chemicals should be observed.

Ensure adequate ventilation.

Keep away from heat and sources of ignition.

Material can accumulate static charges from material handling management. Bond and ground as appropriate. For additional recommendations, consult and applicable guideline such as National Protection Association (NFPA) 77, "Recommended Practices on Static Electricity".

The Minimum Ignition Energy for some organic solids as a dust may be as low as 3 mJ (millijoules). The Minimum Explosive Concentration for some organic solids as a dust may be as low as 0.025 oz/ft3 or ~20 g/m3.

use product only in closed system.

Do not empty into drains.


Keep tightly closed in a dry, cool and well ventilated place.

Avoid release to the environment.

Exposure controls / personal protection

Exposure Limit Values:

No exposure limits have been set for this substance.

The UK HSE (EH40) recommends the following limits for dusts: 10 mg/m3 (8hr TWA) total inhalable dust;  4 mg/m3 (8hr TWA) total respirable dust.

An internal limit for 2,6-di-tert-butylphenol is 10 ppm.

Occupational Exposure Controls:

Engineering controls should be provided which maintain airborne concentrations as low as practicable.

Ventilation should be sufficient to efficiently remove, and prevent buildup of, any vapors, dusts, or fumes that may be generated during handling or thermal processing. In order to ensure appropriate electrical safety practices are followed, consult applicable standards. These may include guidelines such as the National Fire Protection Association (NFPA) 70, "The National Electrical Code" and NFPA 499, "Recommended Practice for the Classification of Combustible Dusts and of Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas". NOTE: since the material's vapors, dusts or fumes can form explosives mixtures in air, ensure that any potential areas where explosions may occur are designed to minimize potential damage. For recommendations to prevent such explosions and associated damage, consult applicable guidelines such as National Fire Protection Association (NFPA) 69, "Standard on Explosion Prevention Systems" and/or NFPA 68, "Guide for Venting Defragrations".

Keep working clothes separately and do not take them home.

Wash hands before eating, drinking, smoking or using toilet facilities.

Respiratoty Protection:

Do not breathe vapours.

Respirator must be worn if exposed to dust -- respirator with combination filter for vapour/particulate.

In case of insufficient ventilation, wear suitable respiratory equipment.

Hand Protection:

Wear plastic or rubber gloves with an estimated breakthrough time of >480 minutes are recommended.  The actual choice of glove should be based on a risk assessment of the tasks being carried out. Remember that a glove offers limited protection and may fail through mechanical damage, thus, other protective measures should be used where appropriate. Please refer to your glove supplier to take into account the conditions under which the glove is to be used.

Eye Protection:

Wear eye/face protection.

If splashes are likely to occur, wear: face-shield.

Skin Protection:

Wear suitable protective working clothes.

Stability and reactivity


Stable at least up to 350°C (8hr).

Conditions to Avoid:

Keep away from heat and sources of ignition.

Material may discolour when in contact with cooper and/or bronze.

Materials to Avoid:

Incompatible with strong oxidizing substances.

Disposal considerations

Disposal Instructions:

Incinerate under controlled conditions, using incinerator suitable for the disposal of noxious chemical waste. In the EU, the waste should be classified in accordance with regulations made under the Directive 91/689/EEC.

Waste From Residues / Unused Products:

Do not discharge into drains or the environment, dispose to an authorised waste collection point. The product contains the following organically bound elements: C H O. Special waste-code WS (CH): 2250.

Disposal should be in accordance with local state or national legislation.

Contaminated Packaging:

Do not reuse empty containers without commercial cleaning or reconditioning.
