- Conclusions:
- The surface tension of a 90 % saturated solution of Octanoic acid, zinc salt, basic was determined to be 38.89 mN/m with a standard deviation of 0.02 mN/m at a mean temperature of 20.0 °C. Since the surface tension is lower than 60 mN/m, Octanoic acid, zinc salt, basic can be regarded as surface-active substance according to Council Regulation (EC) No. 440/2008 Method A.5.

Description of key information
The substance zinc dioctanoate (carbon chain length: 8) can be regarded as surface-active substance. The surface activity depends mainly on the chain lenghts and the water solubility of a substance which is comparable for the substances octanoic acid, zinc salt, basic (38.89 mN/m) and it´s neutral from zinc dioctanoate.
Key value for chemical safety assessment
Additional information
A test on the surface tension according to OECD TG 115 was conducted for the substance octanoic acid, zinc salt, basic (carbon chain length: 8), yielding a result as surface-active substance (38.89 mN/m). Octanoic acid, zinc salt, basic ia a surface-active substance. The substance zinc dioctanoate, which is the neutral from can be regarded as surface-active as well, since surface activity depends mainly on the chain lenghts and the water solubility of a substance which is comparable for the substances octanoic acid, zinc salt, basic and zinc dioctanoate. It can safely be assumed that this substance is 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 zinc dioctanoate 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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
