Description of key information
Captan is a white powder melting at 173 °C. The powder has a very low vapour pressure with 0.000201 Pa. The octanol/water coefficient was found to be Kow 372 (25°C) (log pow 2.57). Captan is slightly soluble in water with 3.77 mg/L but is decomposing with a half-life time of 4.9 hours (pH 7). Captan is stable in different organic solvents (acetone, acetonitril, toluene) stored at ambient temperature for three months. Particle size is determined to a L50D(v,0.5) value of 12.6 µm.
No physical hazards were identified for captan leading to classification according to EU regulation 1272/2008 (e.g. flammability, explosiveness, oxidising properties etc.).
Additional information
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.
