LD50 oral > 2000 mg/kg
LD50 dermal > 2000 mg/kg (based on read-across)

Key value for chemical safety assessment

Additional information

The LD50 oral of the test substance Tri-C18-22 (even numbered)-alkyl 2-hydroxypropane-1,2,3-tricarboxylate was > 2000 mg/kg. This result was supported with data available from two different studies demonstrating a lack of toxic effects up to doses far above the limit dose as recommended by current regulatory guidelines. No mortalities or any toxic effects in rats after administration of doses up to 50000 mg/kg were observed.

The acute dermal toxicity of Tri-C18-22 (even numbered)-alkyl 2-hydroxypropane-1,2,3-tricarboxylate not specifically determined. However, data are available for a structrurally related substance Tri (hexyl, octyl, decyl) citrate with the only difference in the shorter carbon chain length of the ester groups. The LD50 dermal of the structurally related substance was > 2000 mg/kg.
