Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- other: OECD 318
- GLP compliance:
- no
- Executive summary:
The study is technically not feasible.
The preparation of a stock solution was not successful. The resulting suspension is heterogeneous with most of the pigment accumulated in a foam-like upper phase. It is an indication that the pigment is too hydrophobic and thus it is not sufficiently wetted by water. This makes it impossible to perform all other steps in accordance to the guideline TG-318. Thus the evaluation of the stability of Pigment Yellow 128 in simulated environmental media is not possible.

Applicant's summary and conclusion
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.
