Categories
- Category name:
- CDP, TPP, TCP
Justifications and discussions
- Category definition:
- LANXESS Deutschland GmbH has registered three triphenyl phosphates derivates of similar chemical structure: TPP, CDP and TCP. For these three substances a category approach is undertaken.
- Category rationale:
- The category consists of three methyl phenyl phosphoric acid esters with main components of zero (TPP), one (CDP) and three (TCP) methyl groups. Primarily, the number of methyl groups is the leading property for determining the (eco-)toxicity with TPP showing the lowest and TCP the highest toxicity with CDP in between. This trend is based on the fact that the log Kow as a main driver for toxicity is increasing within the category from TPP over CDP to TCP.
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.
