Additional information
Given the rapid hydrolysis and extremely low estimated water solubility level (5.343 x 10 E-13 mg/L to 6.29 x 10E-7 mg/L) for this substance it is not possible to conduct aquatic toxicity studies on it. The primary hydrolysis product, isotridecyl alcohol, is separately registered and PNECs for it were used in this assessment. Since the PNECs for the hydrolysis products are orders of magnitude higher than the water solubility limit of tris isotridecyl phosphite, the conclusion is that the substance is not toxic to aquatic life.

1Extrapolation
method
assessment factor
Experimental sediment toxicity data for Alcohols, C11-14-iso, C13-rich are not available. PNECs for the sediment compartment were
derived based on the results from three long-term endpoints representing three trophic levels, as well as the Equilibrium PartitioningMethod.
PNEC soil 93.7 mg/kg soil dw
Assessment
factor
1Extrapolation
method
assessment factor
Alcohols, C11-14-iso, C13-rich is expected to have a low potential to produce toxicity in terrestrial species (earthworm and plants), based on
(Q)SAR predictions and the Equilibrium Partitioning Method.
PNEC oral 22.22 mg/kg food
Assessment
factor
90
Based on a 13 week rat NOAEL of 100 mg/kg/d with iso-undecanol. Conversion factor for a rat of 20 bw/dfi and an assessment factor for a
90 day study (90).
An assessment of secondary poisoning was not conducted. Data exists indicating that
bioconcentration potential in fish is low (see Section 4.2.1.2 of CSR). Therefore, it can be
concluded that Alcohols, C11 -14 -iso, C13 -rich does not pose a risk towards top predators
as it is not expected to bioaccumulate through the food chain. Also, this substance is not
classified for long-term effects (i.e. not a CMR).
Alcohols, C11 -14 -iso, C13 -richis classified N, R50 for the environment. Although it demonstrates acute aquatic toxicity in the range of 0.1
to 1mg/L, it is also rapidly biodegradable and has a BCF less than 100 (based on dietary and aqueous studies).
Phosphorous Acid PNECs
(fromVan Iperen Registration of Phosphorous Acid, Potassium Salt as of 8 April 2014)
PNEC aqua (freshwater):137 µg/L
PNEC STP:100 mg/L
PNEC sediment (freshwater):0.117 mg/kg dw
PNEC soil:1 mg/kg dw
Conclusion on classification
Substance is not toxic to the aquatic environment based on its very low water solubility and the fact that resulting concentrations of hydrolysis products (isotridecanol and phosphorus acid) are orders of magnitude lower than toxicity values for the hydrolysis products.
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).
