Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Stability

In accordance with Annex X of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, information regarding phototransformation in air, as well as in water and soil, is not mandatory information requirement.

 

In Annex VIII Column 2 of the REACH Regulation it states that a study on the Hydrolysis as function of pH does not need to be conducted if the substance is highly insoluble. A study on the Hydrolysis as function of pH is not required as Behenyl Bottoms was determined to have a solubility below the limit of quantification (<1mg C/L) in a reliable OECD 105 study and can therefore be regarded as insoluble.

 

Biodegradation

In a reliable OECD 301B Ready Biodegradability study Behenyl Bottoms were determined to be inherently biodegradable in water.

In Annex IX column 2 of the REACH Regulation, it says that a study on the "Biodegradation in Water and Sediment" and a study on "Biodegradation in soil" does not need to be conducted if "direct and indirect exposure of sediment(soil) is unlikely."  Therefore, a study on the "Biodegradation in Water and Sediment" and a study on "Biodegradation in soil" does not have to be conducted forBehenyl Bottoms, characterized asC18-22, distillation residues (CAS No. 1160164-88-4).

In accordance with the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, "mode of degradation in actual use" is not a standard information requirement.

 

Bioaccumulation

Behenyl Bottoms are characterised as Alcohols, C18-22, distillation residues and the data requirement for bioaccumulation is waived. The REACH requirement in Annex IX for a study on bioaccumulation in aquatic species is not needed if the substance has a low potential for bioaccumulation and/or a low potential to cross biological membranes. The waiver argumentations are based on the technical difficulties associated with conducting bioaccumulation studies, the low toxicity in aquatic organisms and the low toxicity in mammals resulting in the unlikely potential for secondary poisoning.

 

Transport and Distribution

Behenyl Bottoms, characterized as Alcohols, C18-22, distillation residues (CAS No. 1160164-88-4) was assessed for its absorption/desorption potential by determining the Log Koc. In a reliable (Klimisch 1) GLP compliant study conducted according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)) the extrapolated Log Koc of Behenyl Bottoms was found to be> 6.61.

 

In accordance with the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, determination of Henry's Law constant and distribution are not mandatory information requirements.
