Additional information

In accordance with Annex IX column 2 of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, the hydrolysis as a function of pH study does not need to be conducted if the substance is highly insoluble.


In a reliable (Klimisch 1) OECD guideline 105, GLP compliant study the solubility ofBehenyl Bottoms, characterized asC18-22, distillation residues was determined to be below the limit of quantification of the apparatus used at <1 mg C/L. On the basis of Behenyl Bottoms being highly insoluble the requirement for a hydrolysis as a function of pH study is waived.
