Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
There are no ecotoxicoloigcal data available for pentaerythritol tetrastearate (CAS 115-83-3). Therefore, read-across to the structurally related substances fatty acids, C16-18 and C18-unsatd., esters with pentaerythritol (CAS 85711-45-1), 2,2-bis[[(1-oxoisooctadecyl)oxy]methyl]-1,3-propanediyl bis(isooctadecanoate) (CAS 62125-22-8), decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid (CAS 71010-76-9), pentaerythritol tetraoleate (CAS 19321-40-5) and fatty acids, C16-18 and C18-unsatd., tetraesters with pentaerythritol (CAS 68604-44-4) was conducted in order to fulfil the standard information requirements in compliance with Annex XI, 1.5, of Regulation (EC) No 1907/2006. Based on the high degree of similarity between the structural and physico-chemical properties of the target and source substances, these are considered as suitable representatives for the assessment of the short-term toxicity to fish, short and long-term toxicity to aquatic invertebrates, algae and toxicity to microorganisms of the target substance. A detailed analogue approach justification is provided in the technical dossier (see IUCLID Section 13).
All experimental studies available for the source substances were performed according to internationally accepted guidelines. The lowest endpoint for short-term toxicity to fish was determined to be LC50 > 100 mg/L (nominal). For aquatic invertebrates the EC50 was determined to be > 100 mg/L (nominal) and the NOELR ≥ 135 mg/L (nominal). For algae the EL50 was determined to > 100 mg/L and the NOELR ≥ 100 mg/L (nominal). An EC50 and EC10 of > 1000 mg/L were determined for microorganisms.
Based on the available results from structurally related source substances, it can be concluded that pentaerythritol tetrastearate will not exhibit aquatic effects up to the limit of water solubility.
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).
