SAR Aliphatic Amines 8/2008 

FISH 96-h LC50 (Mortality) 

ESTIMATED TOXICITY: 

The fish 96-h LC50 values used to develop this SAR were measured and the octanol water 

partition coefficients (Kow) were calculated using the computer program, KOWWIN (Version 

1.67). The SAR equation used to estimate toxicity is: 

Log 96-h LC50 (mmol/L) = -0.6016 (log Kow) + 0.4479 

The LC50 is in millimoles per liter (mM/L); N = 117 + 23; and the Coefficient of Determination (R2

) 

= 0.7609. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the 

compound. 

Maximum Kow: 6.0 

Maximum MW: 1000

APPLICATION: 

This SAR may be used to estimate toxicity for aliphatic amines. 

LIMITATIONS: 

For aliphatic amines with log Kow values greater than 7.0, a test duration of greater than 96 hours 

may be required for proper expression of toxicity. Also, if the toxicity value obtained by the use of 

this equation exceeds the water solubility of the compound (measured or estimated), mortalities 

greater than 50% would not be expected in a saturated solution during an exposure period of 96 

hours.

Log 48-h LC50 (mmol/L) = -0.5119 (log Kow) - 0.7278 

The LC50 is in millimoles per liter (mM/L); N = 44 + 15; and the Coefficient of Determination (R2

) 

= 0.554. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the 

compound.

APPLICATION: 

This SAR may be used to estimate toxicity for aliphatic amines. 

LIMITATIONS: 

For aliphatic amines with log Kow values greater than 5.0, a test duration of greater than 48 hours 

may be required for proper expression of toxicity. Also, if the acute toxicity value obtained by the 

use of this equation exceeds the water solubility of the compound (measured or estimated), 

significant mortalities would not be expected in a saturated solution during an exposure period of 

48 hours.

ESTIMATED TOXICITY: 

The green algae 96-h EC50 values used to develop this SAR were measured, and the octanol 

water partition coefficients (Kow) were calculated using the computer program, KOWWIN 

(Version 1.67). The SAR equation used to estimate toxicity is: 

Log 96-h EC50 (mmol/L) = -0.3708 (log Kow) -1.3744 

The EC50 is in millimoles per liter (mM/L); N = 49 + 10; and the Coefficient of Determination (R2

ESTIMATED TOXICITY: 

The fish chronic values (ChV) used to develop this SAR were measured and the octanol water 

partition coefficients (Kow) were calculated using the computer program, KOWWIN (Version 

1.67). The SAR equation used to estimate toxicity is: 

Log ChV (mmol/L) = -0.5648 (log Kow) - 1.3894 

The ChV is in millimoles per liter (mM/L); N = 3; and the Coefficient of Determination (R2

DAPHNID ChV 

ESTIMATED TOXICITY: 

The daphnid chronic values (ChV) used to develop this SAR were measured and the octanol 

water partition coefficients (Kow) were calculated using the computer program, KOWWIN 

(Version 1.67). The SAR equation used to estimate toxicity is: 

Log ChV (mmol/L) = -0.0977 (log Kow) - 3.7304 

The ChV is in millimoles per liter (mM/L); N =3; and the Coefficient of Determination (R2

) = 

0.9538. To convert the ChV from mM/L to mg/L, multiply by the molecular weight of the 

compound.

DAPHNID 48-h LC50

ESTIMATED TOXICITY: 

The daphnid 48-h LC50 values used to develop this SAR were measured, and the octanol water 

partition coefficients (Kow) were calculated using the computer program, KOWWIN (Version 

1.67). The SAR equation used to estimate toxicity is: 

Log 48-h LC50 (mmol/L) = -0.1509 (log Kow) – 1.0196 

The LC50 is in millimoles per liter (mM/L); N = 6 + 2; and the Coefficient of Determination (R2

) = 

0.3151. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the

FISH 14-d LC50 (Mortality) 

ESTIMATED TOXICITY: 

The fish 14-d LC50 values used to develop this SAR were measured and the octanol 

water partition coefficients (Kow) were calculated using the computer program, 

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log 96-h (mmol/L) = - 1.223 (log Kow) + 3.7379 

The LC50 is in millimoles per liter (mM/L); N = 1 + 1; and the Coefficient of 

Determination (R2

) = N/A. To convert the LC50 from mM/L to mg/L, multiply by the 

molecular weight of the ester.

APPLICATION: 

This SAR may be used to estimate toxicity for the following esters: 

 1. Acetates

 3. Dicarboxylic aliphatics 

 4. Phthalates derived from aliphatic alcohols and phenol. 

Page 54 of 148
LIMITATIONS: 

If the log Kow value is greater than 6.0, or if the compound is solid and the LC50 

exceeds the water solubility by 10X, no effects at saturation are predicted.

GREEN ALGAE 96-h EC50 (Growth) 

ESTIMATED TOXICITY: 

The green algae 96-h EC50 values used to develop this SAR were measured and the 

octanol water partition coefficients (Kow) were calculated using the computer program, 

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log 96-h EC50 (mmol/L) = -0.6744 log (Kow) + 0.4247 

The EC50 is in millimoles per liter (mM/L); N = 20 + 6; and the Coefficient of 

Determination (R2

) = 0.8426. To convert the EC50 from mM/L to mg/L, multiply by the 

molecular weight of the ester.

GREEN ALGAE ChV 

ESTIMATED TOXICITY: 

The green algae chronic values (ChV) used to develop this SAR were measured and the 

octanol water partition coefficients (Kow) were calculated using the computer program, 

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log ChV (mmol/L) = -0.5331 (log Kow) - 0.4564 

The ChV is in millimoles per liter (mM/L); N = 13 + 5; and the Coefficient of 

Determination (R2

) = 0.721. To convert the ChV from mM/L to mg/L, multiply by the 

molecular weight of the compound.

APPLICATIONS: 

This SAR may be used to estimate toxicity for the following esters: 

 1. Acetates 

 2. Benzoates 

 3. Dicarboxylic aliphatics 

 4. Phthalates derived from aliphatic alcohols and phenol. 

LIMITATIONS: 

If the log Kow value is greater than 8.0, or if the compound is solid and the ChV exceeds 

the water solubility by 10X, no effects at saturation are predicted.

FISH 96-h LC50 

ESTIMATED TOXICITY: 

The fish 96-h LC50 values used to develop this SAR were measured and the octanol water 

partition coefficients (Kow) were calculated using the computer program, KOWWIN (Version 

1.67). The SAR equation used to estimate toxicity is: 

Log LC50 (mmol/L) = -0.8799 log Kow + 1.6467 

The LC50 is in millimoles per liter (mM/L); N = 327 + 61; and the Coefficient of Determination 

(R2

) = 0.8753. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the 

compound.

SAR NEUTRAL ORGANICS 07/20/2006

FISH 14-d LC50 

ESTIMATED TOXICITY: 

The fish 14-d LC50 values used to develop this SAR were measured and the octanol 

water partition coefficients (Kow) were calculated using the computer program, 

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log 14-d LC50 (mmol/L) = -0.8729 log Kow + 1.6375 

The LC50 is in millimoles per liter (mM/L); N = 70 + 5; and the Coefficient of 

Determination (R2

) = 0.9173. To convert the LC50 from mM/L to mg/L, multiply by the 

molecular weight of the compound. 

 

Maximum Kow: 6.0 

Maximum MW: 1000

SAR NEUTRAL ORGANICS 07/20/2006

DAPHNID 48-h LC50 

ESTIMATED TOXICITY: 

The daphnid 48-h LC50 values used to develop this SAR were measured and the 

octanol water partition coefficients (Kow) were calculated using the computer program, 

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log 48-h LC50 = -0.8157 (log Kow) + 1.2695 

The LC50 is in millimoles per liter (mM/L); N = 115 + 37; and the Coefficient of 

Determination (R2

) = 0.7712. To convert the LC50 from mM/L to mg/L, multiply by the 

molecular weight of the compound.

SAR NEUTRAL ORGANICS 07/20/2006

GREEN ALGAE 96-h EC50 

ESTIMATED TOXICITY: 

The green algae 96-h EC50 values used to develop this SAR were measured and the 

octanol water partition coefficients (Kow) were calculated using the computer program, 

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log 96-h EC50 (mmol/L) = -0.6271 log Kow + 0.5687 

The EC50 is in millimoles per liter (mM/L); N = 51 + 11; and the Coefficient of 

Determination (R2

) = 0.5956. To convert the EC50 from mM/L to mg/L, multiply by the 

molecular weight of the compound. 

Maximum Kow: 6.4 

Maximum MW: 1000

FISH 30-d ChV 

ESTIMATED TOXICITY: 

The fish 30-d chronic values (ChV) used to develop this SAR were measured and the 

octanol water partition coefficients (Kow) were calculated using the computer program, 

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log ChV (mmol/L) = - 0.8508 log Kow + 0.6063 

The ChV is in millimoles per liter (mM/L); N = 46 + 7; and the Coefficient of 

Determination (R2

) = 0.7393. To convert the ChV from mM/L to mg/L, multiply by the 

molecular weight of the compound. 

Maximum Kow: 8.0 

Maximum MW: 1000

KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log 16-d ChV (mmol/L) = - 0.7469 log Kow + 0.1961 

The ChV is in millimoles per liter (mM/L); N = 29 + 1; and the Coefficient of 

Determination (R2

) = 0.8593. To convert the ChV from mM/L to mg/L, multiply by the 

molecular weight of the compound.

ESTIMATED TOXICITY: 

The saltwater mysid shrimp 96-h LC50 values used to develop this SAR were measured 

and the octanol water partition coefficients (Kow) were calculated using the computer 

program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is: 

Log 96-h LC50 (mmol/L) = - 1.1897 log Kow + 2.2651 

The LC50 is in millimoles per liter (mM/L); N = 14 + 1; and the Coefficient of 

Determination (R2

FISH 14-d LC50 (Mortality) 

ESTIMATED TOXICITY: 

No adequate data were available for the phenols SAR fish 14-d LC50 endpoint. Predictions for this 

endpoint are based on SARs for neutral organics. The neutral organic SAR equation used to estimate 

toxicity is:

DAPHNID 48-h LC50 (Mortality) 

ESTIMATED TOXICITY: 

The daphnid 48-h LC50 values used to develop this SAR were measured and the octanol water partition 

coefficients (Kow) were calculated using the computer program, KOWWIN (Version 1.67). The SAR 

equation used to estimate toxicity is: 

Log 48-h LC50 (mmol/L) = - 0.5667 (log Kow) - 0.1481 

The LC50 is in millimoles per liter (mM/L); N = 63 + 7; and the Coefficient of Determination (R2

GREEN ALGAE 96-h EC50 (Growth) 

ESTIMATED TOXICITY: 

The green algae 96-h EC50 values used to develop this SAR were measured and the octanol water 

partition coefficients (Kow) were calculated using the computer program, KOWWIN (Version 1.67). The 

SAR equation used to estimate toxicity is: 

Log 96-h EC50 (mmol/L) = -0.6089 (log Kow) + 0.599 

The EC50 is in millimoles per liter (mM/L); N = 40 + 4; and the Coefficient of Determination (R2

) = 0.6748. 

To convert the EC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

FISH 60-d ChV 

ESTIMATED TOXICITY: 

The fish 60-d chronic values (ChV) used to develop this SAR were measured and the octanol water 

partition coefficients (Kow) were calculated using the computer program, KOWWIN (Version 1.67). The 

SAR equation used to estimate toxicity is: 

Log ChV (mmol/L) = 0.0077 (log Kow) - 4.5107 

The ChV is in millimoles per liter (mM/L); N = 3; and the Coefficient of Determination (R2

) = 0.0145. To 

convert the ChV from mM/L to mg/L, multiply by the molecular weight of the compound.

FISH (SW) 96-h LC50 (Mortality) 

ESTIMATED TOXICITY: 

The fish (sw) 96-h LC50 values used to develop this SAR were measured and the octanol water partition 

coefficients (Kow) were calculated using the computer program, KOWWIN (Version 1.67). The SAR 

equation used to estimate toxicity is: 

Log 96-h LC50 (mmol/L) = -0.9959 (log Kow) + 1.0316 

The LC50 is in millimoles per liter (mM/L); N = 5 + 2; and the Coefficient of Determination (R2

) = 0.8224. 

To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the compound.
