Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data has been obtained from studies conducted with Pentaerythritol.
Aquatic tests covering 3 trophic levels (algae, daphnia, fish) were conducted. For all three trophic levels there was only one short-term study for each and one supportive chronic study with Daphnia, with test concentrations based on nominals concentrations.
The results of these studies indicated that the L(E)C50 values were all >100 mg/L (Fish LC50 >100 mg/L, Daphnia EC50 >1000 mg/L, Algal ErC50 = >1000 mg/L).
However, since there is insufficient data available for the freshwater organisms, further testing proposals for long term studies (OECD 210, OECD 211) are included in sections 6.1.2 and 6.1.4 to fulfill the data requirement (ANNEX IX).
It has to be noted that, the lowest L(E)C50>100 mg/l obtained from the available acute studies performed with the substance on aquatic organisms neither showed any hazard, nor fell under any of the identified hazard categories (CLP classification, article 14) for the protection target reported in the Section 3 of REACH Annex I. To comply with the REACH regulation, no PNEC was derived for any of the environmental compartments (ECHA GD document B.8.4).
If new endpoints obtained from the proposed chronic studies on fish and daphnia will show further hazard, PNEC will be derived to perform a quantitative risk assessment.
As the substance is readily biodegradable and as no significant exposure is expected, no PNEC for the STP is required. Moreover, data are available from a respiration inhibition study and a bacterial growth inhibition study. The lowest available endpoint is an EC10 for Pseudomona putida of >500 mg/L. As such, no risk to STP microorganisms is expected.
Conclusion on classification
The test substance demonstrates no signficant toxicity to aquatic organisms. As such no hazards are indentified for the environment and the substance should not be considered harmful to aquatic organisms.
No classification is triggered based on available data, according to EEC Council Directive 79/831/EEC Annex VI, Part II (D) as described in Commission Directive 93/21/EEC or Regulation (EC) No 1272/2008,
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).
