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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Guidance on Safe Use
Administrative data
First-aid measures
Emergency measure - Inhalation: Remove patient to fresh air. Seek medical attention if
symptoms develop.
Emergency measure - Eyes: Rinse thoroughly with plenty of water
Emergency measure - Skin: Wash with plenty of water
Emergency measure - Ingestion: Seek medical attention
Fire-fighting measures
Recommended extinguishing agent: Combustion products may contain carbon oxides. Suitable
extinguishing agents are carbon dioxide and water.
Accidental release measures
Emergency measures in case of spillage: Contain the spill. Decompose the substance in hot water
(>46 deg C). tert.Butylhydroperoxide is not formed when the
substance is decomposed thermally.
Handling and storage
Handling: Protective clothing, including PVC gloves (eg Semperit VH,
Sempersoft), should be worn. Goggles with mistless
sight-glass made of cellone in a basket shape designed to
cover ordinary spectacles are recommended to provide eye
protection. Avoid breathing dust, wear a dust mask
(half-mask type) made of silicone rubber with a P3 filter
(i.e. filter screens particles >0.3 microns, see CEN
standard paragraph pr EN 143).
Storage: Store in isolation at temperatures below 5 deg C. Packing
should not be gas-tight.

Stability and reactivity
Danger other than fire: At temperatures above 5 deg C, carbon dioxide will be
generated. The substance slowly hydrolyses in water to
yield tert.butylhydroperoxide which, at high
concentrations, may give the wet decomposition mixture skin
and eye irritating properties.
Disposal considerations
Industry - Possibility of recovery/recycling: Recovery for reuse is not possible.
Industry - Possibility of neutralisation: Thermal decomposition with water at a temperature >46 deg C
will neutralise the hazardous property of the substance.
Industry - Possibility of destruction: controlled discharge: Disposal at a landfill site is not recommended. Discharge
to watercourses may be possible after decomposition in
water at >46 deg C.
Industry - Possibility of destruction - incineration: Recommended method
Industry - Possibility of destruction - water purification: Not recommended but no unfavourable effects to systems are
envisaged for the substance or the decomposition products
after decomposition in water at >46 deg C.
Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
