Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Hydrolysis:
A hydrolysis study does not need to be conducted if the substance is highly insoluble in water, therefore, this endpoint is waived.
Biodegradation
Biodegradation in water: Screening:
In an OECD 301B study, conducted according to GLP, the test material attained 20% degradation after 28 days and is considered not readily biodegradable under the strict terms and conditions of OECD 301B. The test material did attain 7% degradation by day 21, an indication of inherent biodegradation between days 21 through 28.
Biodegradation in water and sediment:
Although an OECD Guideline 308 study would demonstrate that radioactivity detected in bound residues can be mineralised to CO2 in two aerobic sediment systems, the results of this feasibility study demonstrate that conducting a full study would not generate any further information and it is unlikely that a full study would meet the objectives of the OECD Guideline 308 in aerobic or anaerobic aquatic sediment systems.
Biodegradation in soil:
The results of this feasibility trial demonstrate that conducting a full study according to OECD Guideline 307, “Aerobic and Anaerobic Transformation in Soil”, would not provide any further useful information. It is unlikely that a full study would meet the objectives of the OECD Guideline 307.
Bioaccumulation
Bioaccumulation:
The following bioaccumulation factors (BCF) have been predicted based on the constituents identified in Section 1.2 (Section 1.1, Table 2 of the Chemical Safety Report) of the registered substance using the Estimation Programs Interface (EPI) suite™ developed by the US Environmental Protection Agency's Office of Pollution Prevention and Toxics and Syracuse Research Corporation (SRC)BCFBAF v3.01.
Phosphoric acid, monooctadecyl ester (CAS Number 2958-09-0):
The calculated log BCF was predicted to be 2.21.
Phosphoric acid, monohexadecyl ester (CAS Number 3539-43-3):
The calculated log BCF was predicted to be 2.65.
Phosphoric acid, dioctadecyl ester (CAS Number 3037 -89 -6):
The calculated log BCF waspredicted to be -0.049.
Phosphoric acid, dihexadecyl ester (CAS Number 2197-63-9):
The calculated log BCF waspredicted to be -0.047.
Hexadecyl octadecyl hydrogen phosphate (CAS Number 93803-11-3):
The calculated log BCF was predicted to be -0.049.
Transport and distribution
Adsorption / desorption:
The following adsorption coefficients have been predicted based on the constituents identified in Section 1.2 (Section 1.1, Table 2 of the Chemical Safety Report) of the registered substance using the Estimation Programs Interface (EPI) suite™ developed by the US Environmental Protection Agency's Office of Pollution Prevention and Toxics and Syracuse Research Corporation (SRC) KOCWIN v2.00.
Phosphoric acid, monooctadecyl ester (CAS Number 2958-09-0):
The calculated log Koc was predicted to be 4.872.
Phosphoric acid, monohexadecyl ester (CAS Number 3539-43-3):
The calculated log Koc was predicted to be 4.35.
Phosphoric acid, dioctadecyl ester (CAS Number 3037 -89 -6):
The calculated log Koc waspredicted to be 9.595.
Phosphoric acid, dihexadecyl ester (CAS Number 2197-63-9):
The calculated log Koc waspredicted to be 8.55.
Hexadecyl octadecyl hydrogen phosphate (CAS Number 93803-11-3):
The calculated log Koc was predicted to be 9.07.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
