Description of key information
Adsorption / desorption
The Soil Adsorption Coefficient i.e Koc value of 1,1-diethoxy-3,7-dimethylocta-2,6-diene was estimated using EPI suite KOCWIN (v2.00) program as 655 L/kg (log Koc=2.81) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 1,1-diethoxy-3,7-dimethylocta-2,6-diene has a Moderate sorption to soil and sediment and therefore have slow migration potential to groundwater.
Additional information
Adsorption / desorption
Three results including different predicted data from validated models and from US EPA screening report for adsorption (KOC) endpoint of target chemical 1,1-diethoxy-3,7-dimethylocta-2,6-diene (Cas no. 7492-66-2)were summarized as follows:
First study from prediction by KOCWIN model (v2.00) of EPI suite which indicate the adsorption value of 1,1-diethoxy-3,7-dimethylocta-2,6-diene was estimated as 655 L/kg(log Koc=2.81) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 1,1-diethoxy-3,7-dimethylocta-2,6-diene has a Moderate sorption to soil and sediment and therefore have slow migration potential to groundwater.
Above result is assist by U.S. Environmental Protection Agency September,Hazard Characterization Document, 2009 which suggest the Adsorption in soil (log Koc) factor of test chemical Citral diethyl acetal (Cas no.7492-66-2) i.e 1,1-diethoxy-3,7-dimethylocta-2,6-diene was reported to be 2.13 (Dimensionless).This Log Koc suggest that the chemical has moderate mobility in soil compartment.
And Result From CompTox Chemistry Dashboard using OPERA (OPEn (quantitative) structure-activity Relationship Application) V1.02 model in which calculation based on PaDEL descriptors (calculate molecular descriptors and fingerprints of chemical) indicate the adsorption coefficient i.e KOC for test substance 1,1-diethoxy-3,7-dimethylocta-2,6-diene was estimated to be 257 L/Kg.The predicted KOC result based on the 5 OECD principles. Thus based on the result it is concluded that the test substance 1,1-diethoxy-3,7-dimethylocta-2,6-diene has moderate mobility in soil compartment.
Thus all available studies for adsorption endpoint come to conclusion that the test substance 1,1-diethoxy-3,7-dimethylocta-2,6-diene (Cas no. 7492-66-2) is expected to have low to moderate mobility in soil and sediment compartment.
