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

Acute toxicity towards plants was tested on Avena sativa (oat), Glycine max (soy bean) and Brassica napus (rape) according to OECD guideline 208. The test was conducted according to OECD 208 using Chlorhexidine digluconate as test substance. As Chlorhexidine base is the active component, the results can be converted to equivalents of CHD-Base. No effects on seedling emergence were observed at the highest concentrations tested (NOECs were always ≥ 563 mg CHD-Base/kg dry soil). Seedling growth, as determined by shoot fresh-weight and -height, was a more sensitive endpoint displaying EC50s between 296 and > 563 mg CHD-Base/kg dry soil.

Key value for chemical safety assessment

Short-term EC50 or LC50 for terrestrial plants:
