Description of key information

The substances in the lithium salts of monocarboxylic acids C14 -C22 category have relative densities of just above 1, in the range of 1.025 to 1.07.

Key value for chemical safety assessment

Additional information

The relative density of substances in the lithium salts of monocarboxylic acids C14-C22 category have been determined in GLP-compliant pycnometer studies following OECD guideline 109. The data on lithium myristate, lithium 12 -hydroxystearate and lithium behenate are taken from proprietary study reports (Harlan 2012, Harlan 2013). The test data for the endpoint is supported by published data on lithium stearate from CIR (1982). Studies are currently ongoing for 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.
