Description of key information
No toxicity was observed at a concentration of 12.9 mg/L test item for rosin, fumarated, reaction products with formaldehyde. This result is read across to rosin, fumarated.
The NOEC for resin acids and rosin acids,
maleated, calcium salts was determined to be 1000 mg/L.
The NOEC for resin acids and rosin acids, maleated, sodium salts was
determined to be 32 mg/L.
Key value for chemical safety assessment
Additional information
Differences in ecotoxicity have been observed between fumarated and maleated category members. For this reason, read across between fumarated and maleated substances is not used for ecotoxicity endpoints.
For fumarated substances, ecotoxicity endpoints and environmental classification are assessed based on data for the substance itself, where available, or based on read across from another fumarated rosin substance. One set of PNECs has been derived to cover all fumarated rosin substances, based on the most sensitive ecotoxicity result available for any fumarated rosin substance.
The ecotoxicity of maleated substances is affected by the solubility of the test item, with more soluble substances rosin, maleated and resin acids and rosin acids, maleated sodium salts showing higher aquatic toxicity compared to the poorly soluble substance resin acids and rosin acids, maleated calcium salts. Therefore, ecotoxicity endpoints and environmental classification of resin acids and rosin acids, maleated calcium salts are completed based on data for the substance itself rather than using read across from more soluble maleated substances. However, PNECs have been derived based on pooled data, with one set of PNECs derived to cover all maleated substances within the category. The most sensitive result for any maleated rosin substance has been used as the key value for PNEC derivation.
Toxicity to microorganisms data are available for some category members, and the results are outlined below.
Rosin fumarated
No data are available for rosin, fumarated for this endpoint. Data are therefore read across from another fumarated rosin substance, rosin, fumarated, reaction products with formaldehyde, which is not being registered under REACH but would fit within this category. The results are taken from a toxicity control carried out as part of an OECD 301B CO2evolution test (Harlan Laboratories Ltd., 2010). In the toxicity control the biodegradation rate of a reference substance (sodium benzoate) known to be readily biodegradable is followed in the presence of the test item. The test item did not exhibit any inhibitory effects on the microbial inoculums. The NOEC was reported as 12.9 mg/L.
Rosin maleated
No data are available for rosin, maleated for this endpoint. Data are read across from resin acids and rosin acids, maleated sodium salts as another partially soluble maleated rosin substance.
Resin acids and rosin acids, maleated sodium salts
The results for resin acids and rosin acids, maleated, sodium salts are taken from a GLP-compliant study following OECD guideline 209 (Laus, 2013). The 3-hour EC50 was determined to be greater than the highest test concentration with the result reported as 5500 mg/L (extrapolated). The NOEC was reported as 32 mg/L.
Resin acids and rosin acids, maleated calcium salts
The results for resin acids and rosin acids, maleated, calcium salts are taken from a GLP-compliant study following OECD guideline 209 (Laus, 2013). The EC50 was determined to be greater than the highest test concentration, and was reported as >1000 mg/L and the NOEC was reported as 1000 mg/L.
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).
