Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 415-490-5 | CAS number: 141773-73-1 HELVETOLIDE
Endpoint summary
Administrative data
Description of key information
Physico-chemical properties were determined from experimental testing. Some endpoints were waived, based on chemical structure of the constituents.
The substance is liquid at ambient temperature, with low volatility.
In water, it is slightly soluble, less dense (so expected to float), with no dissociation anticipated, and no significant surface-active properties.
It has potential for bioaccumulation and aquatic chronic toxicity, based on CLP criteria.
It is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.
