Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Data waiving (other justification): According to the column 2 of REACH Annex VIII, the study does not need to be conducted since the substance is expected to have low potential for adsorption based on the low octanol-water partition coefficient (log Kow < 3).
Supporting study: KOCWIN v2.00, MCI method. Soil adsorption of propyltriacetoxysilane was estimated to be: Koc = 15.89 L/kg and Log Koc = 1.201.
