EC number: 271-080-4 | CAS number: 68515-39-9 A complex combination of hydrocarbons produced by the esterification of phthalic anhydride with tridecyl alcohol. It consists predominantly of C13 primary aliphatic alcohols, C11-13 paraffins and saturated and unsaturated C26 ethers and boiling in the range of approximately 120°C to 280°C (248°F to 536°F).

Description of key information
Additional information
Stability:
The registered substance is comprised of constituents with the potential to degrade in the atmosphere from hydroxyl radical attack and photodegradation can be a predominant daylight atmospheric degradation process for this substance (half-life <10 hours). The registered substance is a UVCB that does not contain constituents that possess a hydrolytically reactive functional group; thus are resistant to hydrolysis, and will not undergo direct photolysis in water and soil. As such, these fate processes will not contribute to a measurable loss of this substance from the environment.
Biodegradation:
The registered substance is expected to be ultimately biodegradable based on aerobic biodegradation studies using standard OECD test guidelines (62% in 49 days) and is not expected to be persistent. Therefore, biotic degradation will significantly contribute to the loss of this substance from the environment.
Bioaccumulation:
The registered substance is expected to have a low to moderate potential for bioconcentration in aquatic species (calculated BCF values <2000).
Transport and distribution:
Soil adsorption is expected to occur at a moderate to high degree (log Koc = 3.9 to 6.9). Henry's Law constant (3 to >1000 Pa.m3/mole for major constituents) indicates that volatilization from water is expected to occur at a moderate to rapid rate.
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.
