Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Degradation products of the spider silk protein are primarily peptides and amino acids, subsequently degraded to carbon dioxide and water which cause no harm to nature. Thus, systemic availability of spider silk protein by aquatic organism following exposure at occupational exposure levels is without toxicological significance. Degradation products of silk proteins like peptides and amino acids are irreplaceable nutritional components for aquatic organism. The spider silk proteins are not water-soluble, thus, bioavailability of the protein itself cannot be expected in the aquatic environment.


Aquatic toxicity testing of the substance is considered as not scientifically necessary. Aquatic toxicity is not to be expected.
