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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Phenol, isopropylated, phosphate (3:1) is dually classified on the basis of triphenyl phosphate content for ecotoxicology. The PNECS presented within the dossier are for the substance where triphenyl phosphate is present at >5%. When triphenyl phosphate is present at <5%, it is the opinion of the registrant that the substance does not display ecotoxic properties, and is only subject to being potentially persistent
Confirmation of this is provided in the associated study reports summarised in support of this registration. Derivation of PNEC for TPP at < 5% is attached below for reference.
The following classifications are applicable:
Triphenyl phosphate is present at >5%
On the basis of effects noted in fish and Daphnia, the substance is deemed to be classified according to Regulation (EC) No 1272/2008 as:
Aquatic Chronic 1; H410: Very toxic to aquatic life with long lasting effects.
Triphenyl phosphate is present at <5%
On the basis of effects noted in fish and Daphnia, the substance is deemed to be classified according to Regulation (EC) No 1272/2008 :
Aquatic Chronic 4; H413: May cause long lasting harmful effects to aquatic life.
The risk assessment covers assessment against both PNECs, however it is only possible to list one set within the dossier. Therefore, the TPP >5% values are listed within the dossier, but should be considered in conjunction with the <5% values below. Please refer to attached documents below.
Conclusion on classification
Classification and labelling:
The substance is dually classified on the basis of triphenyl phosphate content for ecotoxicology. The PNECS presented above are for the substance where triphenyl phosphate is present at >5%. When triphenyl phosphate is present at <5%, it is the opinion of the registrant that the substance does not display ecotoxic properties, and is only subject to being potentially persistent
Confirmation of this is provided in the associated study reports summarised in support of this registration. Derivation of PNEC for TPP at < 5% is attached below for reference.
The following is applicable:
Triphenyl phosphate is present at >5%
On the basis of effects noted in fish and Daphnia, the substance is deemed to be classified according to Regulation (EC) No 1272/2008 as:
Aquatic Chronic 1; H410: Very toxic to aquatic life with long lasting effects.
Triphenyl phosphate is present at <5%
On the basis of effects noted in fish and Daphnia, the substance is deemed to be classified according to Regulation (EC) No 1272/2008 :
Aquatic Chronic 4; H413: May cause long lasting harmful effects to aquatic life.
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.
