Description of key information

Distribution coefficients (Kd) for reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda were in the range 2.1 to 7.9 mL/g and KOC values were in the range 60 to 234 mL/g. Depending on the soil, reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda was shown to be of ‘medium’ or ‘high mobility’ according to the McCall classification.

Additional information

The Koc value of Reaction product of naphthalene, butanol, sulfonated and neutralized by caustic soda is determined by a read-across approach based on analogue substance Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda.

A GLP-compliant study, scored as Klimisch 2 and flagged as a key study, is available on the Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda.

The adsorption characteristics of reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda were determined in three soils and two sediments at 20 ± 2°C according to OECD Guideline 106.

Distribution coefficients (Kd) for reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda were in the range 2.1 to 7.9 mL/g and KOC values were in the range 60 to 234 mL/g. Depending on the soil,reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda was shown to be of ‘medium’ or ‘high mobility’ according to the McCall classification.
