Description of key information
Additional information
The distribution between the organic phase of soil or sediments and the pore water was estimated using EUSES 2.1 model. The Kocis estimated to be 483 for CTP (Ekotoxikologické centrum Bratislava, s.r.o., 2012b) using measured Log Kowof 3.19 (Research Institute for Organic Syntheses Inc.,2007a).
For comparison the soil adsorption coefficient of N-(cyclohexylthio)phthalimide was estimated using KOCWIN v 2.00 as Koc= 351.8L/kg (Kowmethod) using an estimated log Kowof 3.67(Ekotoxikologické centrum Bratislava, s.r.o., 2010c).
According to peer reviewed data from Hazardous Substances Databank (number 7259) the Kocof N-(cyclohexylthio)phthalimide is estimated as 2,300(SRC), using a log Kowof 3.66 (US EPA, 2004) and a regression-derived equation (Lyman et al., 1990). According to a classification scheme (Swann et al., 1983), this estimated Kocvalue suggests that N-(cyclohexylthio)phthalimide is expected to have slight mobility in soil. N-(cyclohexylthio)phthalimide would be expected to hydrolyze in moist soil. According to peer reviewed data from Hazardous Substances Databank (number7259) The Henry's Law constant for N-(cyclohexylthio)phthalimide is estimated as 6.4x10-8atm-cu m/mole(SRC) using a fragment constant estimation method (Meylan, Howard, 1991).This Henry's Law constant indicates that N-(cyclohexylthio)phthalimide is expected to be essentially non volatile from water surfaces (Lyman et al, 1990). N-(cyclohexylthio)phthalimide is not expected to volatilize from moist soil surfaces based on its estimated Henry's Law constant(SRC). N-(cyclohexylthio)phthalimide would be expected to hydrolyze in moist soil and in water; a hydrolysis half-life of 23.3 hours at pH=7 andhas been reported for N-(cyclohexylthio)phthalimide (US EPA, 2004). N-(cyclohexylthio)phthalimide is not expected to volatilize from dry soil surfaces (SRC) based upon an estimated vapour pressure of 3.8x10 -8 mmHg(SRC), determined from a fragment constant method (Lyman, 1985). Henrys Law Constant recalculated using the latest HENRYWIN in 3.20 atis 6.40E-008 atm-m3/mole (Ekotoxikologické centrum Bratislava, s.r.o., 2010d); the result is comparable to value reported by HSDB and US EPA, 2004. The distribution of CTP was calculated according to the fugacity model level III.The main target compartment of CTP is soil with 70.7 % (US EPA, 2004). The distribution of CTP was recalculated according to the latest fugacity model level III using estimated input parameters (Log Kow(KOWWIN v1.67 estimate) = 3.76, Melting Point, (MPBPVP v1.43) estimated as 197.79 (Mean or Weighted MP), Water Solubility Estimate from Log Kow(WSKOWv1.41)at 25°C: 12.61(mg/L)).Calculated distribution as mass amount is 0.202% for air, 23% for water, 76.7% for soil and 0.145% for sediment (Ekotoxikologické centrum Bratislava, s.r.o., 2010b). The recalculated results are comparable to values reported by US EPA 2004, the main target compartment of CTP is soil with 76.7 %.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).
