Description of key information

68.3 mN/m at 20°C; OECD Guideline 115 / EU method A.5; RL2, GLP; read-across MDEA-Esterquat C16-18 and C18 unsatd.

Key value for chemical safety assessment

Additional information

The surface tension of the structurally similar source substance MDEA-Esterquat C16-18 and C18 unsatd. was investigated in a study conducted according to OECD Guideline 115 (Surface Tension of Aqueous Solutions; 1995) and EU Method A.5 (Surface Tension; 2008).

The result in this test is not in line with the expected surface tension behaviour of the test substance (please refer to the discussion on surface tension in the Endpoint summary "Physical and chemical properties").
