Additional information
The High Molecular Weight Phthalate Ester (HMWPE) Category consists of phthalate esters with an alkyl carbon backbone with 7 carbon (C7) atoms or greater. The category is formed on the principle that substances of similar structure have similar toxicological properties. The data available on high molecular weight phthalates demonstrate that members of this category have similar biological activities and toxicological properties; verifying the use of read-across data as an appropriate approach to characterize endpoints. DTDP (C13) is a high molecular weight phthalate ester. Where data maybe lacking for DTDP, DINP (C9) and DIDP (C10), which are also high molecular weight phthalate esters, are used as read-across substances to provide toxicological information.
Like other high molecular weight phthalates, DTDP was not mutagenic in vitro in bacterial mutation assays (with and without metabolic activation). The structurally similar compound DIDP is not clastogenic in the mouse micronucleus assay in vivo. Based on these data, DTDP is not mutagenic or genotoxic.
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
No classification for genetic toxicity or mutagenicity is indicated according to the general classification and labeling requirements for dangerous substances and preparations (Directive 67-548-EEC) or the classification, labeling and packaging (CLP) 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
