Validation
The surface tension of the reference item hexane was determined on 2012-07-16 as 18.33 ± 0.02 mN/m (20 °C) for the Ring Nr. 1, RI 21. This value is in the range of tolerance of ± 1 mN/m acc. to the literature value of 18.42 mN/m at 20 °C.
Due to the fact, that undissolved particles were observed during the preparation overnight of the aqueous test solution, the resulting “solution” was treated additionally with ultrasound for 5 minutes at room temperature. But as there still remained a turbid test solution also in a repeated preparation (treated with ultrasound, stirred overnight and stored for further 5 days at room temperature), the procedure of the preparation was modified for the (final) testing as finally described under ‘Preparation of the test solution’.
Determination of the density
The density of the1 g/L aqueous solution of Fatty acids,C9-13-neo, calcium salts in double distilled water was determined in a preliminary measurement to be 1.006 g/cm³ (20.2 °C) before and 1.005 g/cm³ (20.0 °C) after filtration of the test solution.
Temperature
The temperature of the test solution during the whole measurements was 20.1 °C before filtration and 20.0 °C after filtration (for the last 10 measurements). The test room temperature during these measurements was 20.2 to 21.0 °C.
Time line of the study
After transfer of the test solution into the test vessel 42.8 minutes (before filtration) and 44.6 minutes (after filtration), respectively, were needed to reach an equilibrium at which 10 successive measurements with a standard deviation of ≤ 0.05 mN/m were possible.

Description of key information
Fatty acids, tall-oil, manganese salts represents an inorganic salt containing a mixture of organic acid anions with an average carbon chainlength of 18, it can safely be assumed that this substance is weakly surface active.
Key value for chemical safety assessment
Additional information
Three tests on the surface tension according to OECD TG 115 were recently conducted for a representative sub-set of RMC substances, i.e. calcium bis(2-ethylhexanoate) (carbon chainlength: 6), fatty acids, C6-19-branched, zinc salts (carbon chain length: 6-19) and fatty acids, C9-13, neo, calcium salts (carbon chain length: 9-13), yielding a result as surface-active substance for fatty acids, C6-19-branched, zinc salts (52.5 mN/m) and fatty acids, C9-13, neo, calcium salts (45.8 mN/m) and not surface-active substance for calcium bis(2-ethylhexanoate) (60.22 mN/m). Since fatty acids, tall-oil, manganese salts represents an inorganic salt containing a mixture of organic acid anions with an average carbon chainlength of 18, it can safely be assumed that this substance is weakly surface active. As stated in the ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, R.7.1.18.1, May 2008, p.182, 185, a low surface tension (of below 33 mN/m) is one indicator for aspiration hazard. It can safely be assumed that the surface tension effect of fatty acids, tall-oil, manganese salts is above 33 mN/m, thus further testing is not required (in accordance with Regulation (EC) 1907/2006, Annex VII, section 7.6, Column 2).
