Description of key information

Substances in the lithium salts of monocarboxylic acids C14 -C22 category have melting points between 166°C and 231°C and slowly decompose on melting.

Key value for chemical safety assessment

Additional information

The data on lithium myristate, lithium 12 -hydroxystearate and lithium behenate are taken from proprietary study reports (Harlan 2012, Harlan 2013). The results for the endpoint are supported by data on lithium myristate, lithium palmitate and lithium stearate from Shoeb (1999) and on lithium stearate from US EPA (2011) and Lide (2009). Studies on 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 are currently ongoing (Covance 2020).
