Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In the absence of any significant findings relating to systemic, reproductive or developmental endpoints in appropriate tests, the critical health effect is considered to be corrosion. Trichloro(2,4,4-trimethylpentylsilane is not classified as mutagenic, carcinogenic or sensitising.

The DNEL used for risk characterisation is therefore:

DNEL (long-term, inhalation): 18.1 mg/m3

Qualitative risk characterisation for corrosive effects following dermal exposure will also be required.

There is no potential for exposure of consumers to tricloro(2,4,4-trimethyl)silane by any route, therefore DNELs for consumers are not calculated.
