Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A degradation category approach is applied, based on the very rapid and complete degradation (hydrolysis) of boron trichloride in water to form hydrochloric acid and boric acid. The description and justification of the category is presented in Section 13. The environmental fate depends in each case (also for humid air) on the presence of water or humidity. Therefore it is possible and necessary to describe the environmental fate of BCl3 by the fate of its degradation products.
Relevant information for the 2 degradation products:
Hydrogen chloride:
Following dissociation in water, resultant ions are expected to undergo ion exchange within the soil.
Boric acid:
Boron in sediments and soils will equilibrate with overlying water or pore-water, with the equilibrium favouring the aqueous phase. Boron may leach or dissolve from solids, but rates will vary depending on the matrix. Non-porous solids will retain boron.
The following boron based sorption values (i.e. Kd or Kf) are proposed, if 1 mg/L B is in solution:
Soil: 1.5 mg/kg
Sediment: 2.8 mg/kg
Suspended solids: 3.5 mg/kg
Key value for chemical safety assessment
Additional information
A degradation category approach is applied, based on the very rapid and complete degradation (hydrolysis) of boron trichloride in water to form hydrochloric acid and boric acid. The description and justification of the category is presented in Section 13. The endpoint results of the degradation products are transcribed to boron trichloride.
The environmental fate depends in each case (also for humid air) on the presence of water or humidity. Therefore it is possible and necessary to describe the environmental fate of BCl3 by the fate of its degradation products.
Relevant information for the 2 degradation products:
Hydrogen chloride:
The determination of Koc for the intact molecule is not technically possible to perform. The required test methods are not applicable to molecules which dissociate. Following dissociation in water, resultant ions are expected to undergo ion exchange within the soil.
Boric acid: Based on its high water solubility, relatively low sorption value, low vapour pressure, partition coefficients and environmental distribution, boric acid is considered to be relatively mobile in the environment. Atmospheric boron will wash out via precipitation. Boron in sediments and soils will equilibrate with overlying water or pore-water, with the equilibrium favouring the aqueous phase. Boron may leach or dissolve from solids, but rates will vary depending on the matrix. Non-porous solids will retain boron. The following boron based sorption values (i.e. Kd or Kf) are proposed, if 1 mg/L B is in solution:
Soil: 1.5 mg/kg
Sediment: 2.8 mg/kg
Suspended solids: 3.5 mg/kg
