Conclusions:

The mean surface tension of the Maltitol diluted at 1 g/L in distilled water at 20.0 °C was 71.4 mN/m. The test item was not considered as surface-active in the experimental conditions used.

Executive summary:

The surface tension of maltitol was determined according to EU Method A.5 and OECD 115 and in compliance with the GLP.

The surface tension of the test item at 1 g/L in distilled water was measured using the ring method. The measurements are performed in a thermo-regulated cup at the requested temperature, which is 20.0 °C ± 0.5 °C.

The surface tension of Maltitol diluted at 1 g/L in distilled water at 20.0 °C was 71.4 mN/m ±,0.2 mN/m (mean of 3 assays).

Even if the standard deviation is slightly higher than normaly requested (0.2 in place of 0.1 mN/m), this study is considered as acceptable and the maltitol is not a surface active substance in the experimental conditions.

Description of key information
