Description of key information
Substances in the lithium salts of monocarboxylic acids C14 -C22 category have increasing surface tension with increasing carbon number. As the cut-off for being considered surface active is 60 mN/m and lithium behenate, the longest chain length category member, only slightly exceeds this (61.8 - 65.9 mN/m), category members with carbon chain lengths of less than 22 are considered to have surface active properties. This is supported by experimental data on lithium myristate, which gives a surface tension of 34 mN/m, and lithium 12 -hydroxystearate, which gives a surface tension of 52 mN/m.
Key value for chemical safety assessment
Additional information
The surface tensions of substances in the lithium salts of monocarboxylic acids C14-C22 category have been determined in GLP-compliant studies following OECD guideline 115. The data on lithium myristate, lithium 12 -hydroxystearate and lithium behenate are taken from proprietary study reports (Harlan 2012, Harlan 2013). Studies are currently ongoing for lithium stearate, fatty acids C16 -18 lithium salts, fatty acids C16 -22 lithium salts, fatty acids C16 -18 (even numbered) saturated and C16 -20 (even numbered) unsaturated lithium salts, and tallow lithium salt.
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).
