Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Emergency measure - Inhalation: Not known to be a direct inhalation hazard.  If exposed to

dust, move to area of fresh air.  Seek medical advice if

signs of discomfort.

Emergency measure - Eyes: Rinse immediately with plenty of water for at least 15

minutes.  Seek medical attention if signs of discomfort.

Emergency measure - Skin: Wash with water and mild soap or detergent.  If signs of

discomfort, seek medical attention.   Remove contaminted

clothing and wash thoroughly before re-use.

Emergency measure - Ingestion: Do not induce vomiting.  If ingestion has occurred within

the previous 5 minutes, administer small amounts of milk or

water (approx 160 ml, but less than 240 ml).

Seek medical advice if signs of discomfort.  Show copy of

SDS or label to medical staff.

Fire-fighting measures

Recommended extinguishing agent: Dry foam, powder, water spray, carbon dioxide and other

extinguishing agents.  No adverse reaction with normal

extinguishing agents is known. Evaluate the nature of the

incident before using water.

Product arising from burning: Complete combustion will lead to the formation of carbon

dioxide and water. Incomplete combustion (eg in enclosed

spaces) will result in volatile organic derivatives and

carbon monoxide.

The products of combustion are not considered to be

hazardous except in confined spaces.

Product determined by test: N

Protective equipment: Full protective equipment is recommended including breathing

apparatus, suitable gloves, goggles and face protection.

Precautions suitable for weak organic acids should be taken.

Accidental release measures

Emergency measures in case of spillage: Collect and place into correctly labelled containers and

dispose of as hazardous waste in accordance with local

regulations.  Residues and minor spills may be washed away

with water to process drainage system if permitted under

local regulations.

Protective clothing should be worn including suitable eye

protection, gloves, coveralls and dust mask.

Handling and storage

Handling: Personal protective equipment applicable to a potential

irritant is required, such as rubber gloves, eye/face

protection and coveralls.

There is not considered to be a significant risk of

inhalation when used in an adequately ventilated area,

although precautions are recommended to avoid exposure.

Storage: The substance should be stored in the containers used for

supply, sealed under nitrogen to avoid oxidation.  The

containers should be kept cool (< 25°C) to avoid melting.

Packaging of the substance and or preparation: Slurry transported in 200 litre drums or bulk containers

from site of synthesis for purification.

Purified solid transported in metal or fibre kegs with an

aluminium lining, containing up to 50 kg.

Stability and reactivity

Danger other than fire: Avoid contact with strong oxidising and reducing agents.

Chemical reaction with water: The substance does not react violently with water.

Dust explosion: As with other organic solids, there is a possibility of dust

explosion.  As a precaution, it is recommended that levels

of dust are kept low and equipment is suitably earthed to

prevent electrostatic discharge.

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: The substance is not consumed during use.  The preparation

cannot be recycled and any unused material should be


Industry - Possibility of neutralisation: As a weak organic acid, saponification with suitable strong

base will reduce the potential irritancy of the substance.

Industry - Possibility of destruction: controlled discharge: Not recommended, although suitable treatment methods will

ensure breakdown of the susbtance.

Industry - Possibility of destruction - incineration: This is recommended for large quantites and solvent wastes.

Closed system incinerators with scrubbers should be used in

compliance with local and national legislation.

Industry - Possibility of destruction - water purification: A combination of chemical, physical and biological processes

will remove the substance from water.

Industry - Possibility of destruction - other: No other recommended methods of disposal.

Public at large - Possibility of recovery/recycling: Not applicable to the general public.
