Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The constituents of the substance reaction mass of S2 and S3 hydrolyses to (3-{[3-(trihydroxysilyl)propyl]disulfanyl}propyl)silanetriol and (3-{[3-(trihydroxysilyl)propyl]trisulfanyl}propyl)silanetriol respectively, with a hydrolysis half-life of greater than 40 hours. The other hydrolysis product is ethanol. Given the slow rate of hydrolysis, the environmental hazard assessment is based on the properties of the parent substance in accordance with REACH guidance for Chemical Safety Assessment(Chapter R16).

(3-{[3-(Trihydroxysilyl) propyl]disulfanyl}propyl)silanetriol and (3-{[3-(trihydroxysilyl)propyl]trisulfanyl}propyl)silanetriol are the expected final products of hydrolysis reactions under conditions of a hydrolysis laboratory study. However, other biotic or abiotic reactions may occur over longer time-scales in the environment.
