Additional information

Water compartment is represented by a PNEC derived from an acute short-term value of LC50. Long-term toxicity is not available and testing shall be proposed by the registrant if the chemical safety assessment according to Annex I of the REACH Regulation 1907/2006 indicates the need to investigate further the effects on aquatic organisms.

SEDIMENT

PNEC sediment using Equilibrium Partitioning Method:

The following formula is applied:

PNECsed= Ksusp-water/RHOsusp*PNECwater*1000

PNECwater	Predicted No Effect Concentration in water	[mg.l-1]	0,1
RHOsusp	bulk density of wet suspended matter	[kg.m-3]	1150
Ksusp water	partition coefficient suspended matter water	[m3.m-3]	0,998
PNECsed	Predicted No Effect Concentration in sediment	[mg.kg-1of wet sediment]	0,0868

Ksusp water= Fwatersusp+ Fsolidsusp*Kpsusp/1000*RHOsolid

Kpsusp= Focsusp*Koc

Therefore PNEC sediments = (0,998/1150)*0,1*1000 = 0,0868 mg/kg

The value of Ksusp-water of 0,0868 mg/kg is consistent with the calculated value with EUSES 2.1.1 (non hydrophobic substances).

PNEC marine sediment using Equilibrium Partitioning Method:

Being marine PNEC usually derived by freshwater PNEC with an adding assessment factor of 10, consequently the marine sediment PNEC can be directly derived from PNEC sediment with an assessment factor of 10.

Therefore PNEC marine sediments = 0,0086 mg/kg

SOIL

PNEC soil using Equilibrium Partitioning Method:

The following formula is applied:

PNECsoil= Ksoil-water/RHOsoil*PNECwater*1000

PNECwater	Predicted No Effect Concentration in water	[mg.l-1]	0,1
RHOsoil	bulk density of soil	[kg.m-3]	1700
Ksoil water	partition coefficient soil water	[m3.m-3]	0,318
PNECsoil	Predicted No Effect Concentration in soil	[mg.kg-1 of wet soil]	0.0187

Ksoil water= Fairsoil*Kair-water+Fwatersoil+ Fsolidsoil*Kpsoil/1000*RHOsolid

Kpsoil= Focsoil*Koc

Therefore PNEC soil = (0,318/1700)*0,1*1000= 0. 0187 mg/kg

Conclusion on classification

The substance Sulfosuccinate of lanolin alcohol is not classified toxic for the environmental compartment because it doesn't meet the classification criteria of the CLP regulation n. 1272/2008:

Acute (short-term) data available

Category Acute 1:

96 hr LC50 (for fish) ≤ 1 mg/l and/or

48 hr EC50 (for crustacea) ≤ 1 mg/l and/or

72 or 96 hr ErC50 (for algae or other aquatic plants) ≤ 1 mg/l  

Substances for which adequate chronic toxicity data are not available.

Category Chronic 1:

96 hr LC50 (for fish) ≤ 1 mg/l and/or

48 hr EC50 (for crustacea) ≤ 1 mg/l and/or

72 or 96 hr ErC50 (for algae or other aquatic plants) ≤ 1 mg/land the substance is not rapidly degradable and/or the experimentally determined BCF≥ 500 (or, if absent, the log Kow≥ 4)

Category Chronic 2:

96 hr LC50 (for fish) > 1 to ≤10 mg/l and/or

48 hr EC50 (for crustacea) > 1 to ≤10 mg/l and/or
