Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
First-aid measures
Emergency measure - Inhalation: Evacuate victim to fresh air and seek medical advice
immediately (show the label where possible).
Emergency measure - Eyes: Check and remove contact lenses. Immediately flush eyes with
cold running water for at least 15 minutes keeping eyelids
open. Seek immediate medical attention.
Emergency measure - Skin: Immediately flush skin with cold running water for at least 15 minutes removing any contaminated clothing. Seek
immediate medical attention. Thoroughly launder and contaminated clothing before re-use.
Emergency measure - Ingestion: If ingested, seek medical advice immediately (show the label
where possible). DO NOT induce vomiting.
Fire-fighting measures
Recommended extinguishing agent: Small Fires: Use dry chemical powder.
Large Fires: Use water spray, fog or foam. Do not use water
water jet.
Product arising from burning: COx, NOx, SOx, HCl and Na.
Product determined by test: N
Protective equipment: Self-contained breathing apparatus and full protective
equipment are recommended.
Accidental release measures
Emergency measures in case of spillage: The affected area will be fenced or cordoned off and
individuals will not be allowed to touch or walk through the spilled material unless wearing appropriate protective
clothing. Dust generation will be avoided.
Suitable protective clothing will include gloves and
eye/face protection. As a minimum this will include: splash
goggles, disposable lab coat of low permeability with cuffs, double gloves, shoe covers, and an approved respirator.
Depending upon the nature of the spill (quantity and extent
of spill), additional protective clothing and equipment such
as self-contained breathing apparatus may be needed.
Spilled solids will be collected with a contained vacuum
unit or will be moistened and picked-up so as to minimise
dust generation. The substance will be placed in a suitable properly labelled container for recovery or disposal.
The cleaning will be finised by washing thoroughly with
detergent and water that will be disposed of according to
local and national requirements.
Handling and storage
Handling: The substance will be stored, handled, and used under
conditions of good industrial hygiene, and in conformity
with any local regulations in order to avoid exposure to the extent technically feasible. Engineering controls in the
form of local exhaust ventilation and/or closed system
charging are recommended at the reactor. When engineering controls are not sufficient to control dust exposure,
approved respiratory protection in conformance with EN136 will be worn. For manufacturing areas, skin protection will
be provided in the form of overalls, or full air suits
along with impermeable gloves in conformance with EN368 and EN374, respectively. Rubber, neoprene or other gloves will
be required if solvents, corrosives or other chemicals are present. Gloves will be changed regularly and removed after
overt contamination. Chemical safety eye protection in
conformance with EN166 will be worn if a full-face
respirator is not worn.
Avoid dusting when handling and avoid all possible sources
of ignition (spark or flame). Specific areas will be
designated and restricted to persons trained and qualified
to work with these materials wearing appropriate PPE. A
designated area may encompass all or part of a laboratory,
e.g. a hood.
Storage: Storage will be in sturdy containers or unbreakable outer containers. Store at room temperature 25°C (77°F) or lower.
Store away from direct sunlight.
Eating, drinking etc are prohibited. Access is only to
authorised personnel, appropriately gowned and conforming to
local SOPs. Work clothing is not worn outside facility. All
staff are appropriately trained in safe working procedures
and provided with information on materials and processes.
Packaging of the substance and or preparation: UN approved fibre drums

Stability and reactivity
Danger other than fire: None known
Chemical reaction with water: None known
Dust explosion: Material exhibits explosion characteristics if ignited as a
dust cloud. Material is susceptible to accumulating static
charges during processing. Provide suitable bonding and grounding for containers and process equipment to control
static charge. Powder handling equipment such as dust
collectors, dryers, and mills may require additional
protective measures (e.g. explosive venting).
Dust explosion determined by test: Y
Disposal considerations
Industry - Possibility of recovery/recycling: Discharge to the environment will be minimal. Trace
quantities are destroyed by biological oxidation in
wastewater treatment plants. Recovery of larger spillages of uncontaminated material for subsequent use is
recommended. As material is used in the process, no recycling of material is possible.
Industry - Possibility of neutralisation: No method of neutralization is known.
Industry - Possibility of destruction: controlled discharge: Trace quantities are destroyed by biological oxidation in
wastewater treatment plants.
Industry - Possibility of destruction - incineration: Incineration is recommended for larger quantities. A
closed-cycle incinerator with scrubbers should be employed.
National and local regulations must be observed.
Industry - Possibility of destruction - water purification: The substance should not normally be discharged directly to
the sewage system or aqueous environment. However, there
are unlikely to be adverse effects on sewage treatment
systems, because the substance has been shown not to be
unduly toxic to sewage microorganisms. Therefore trace quantities can be treated in a secondary biological WWTP
before discharge to municipal works.
Industry - Possibility of destruction - other: None known.
Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
Public at large - Possibility of neutralisation: The substance will not enter the public domain.
Public at large - Possibility of destruction: controlled discharge: The substance will not enter the public domain.
Public at large - Possibility of destruction - incineration: The substance will not enter the public domain.
Public at large - Possibility of destruction - water purification: The substance will not enter the public domain.
Public at large - Possibility of destruction - others: The substance will not enter the public domain.
