- Specific details on test material used for the study:
- Test Item Code: 2012-004738
Batch / Lot number: SZB9174XV
Active ingredient: Captan
Content of a.i. (analysed): 99.6 % (w/w)
Appearance / Colour: White powder
Certificate of Analysis: 21 March 2011
Expiry date: 23 June 2016
Storage conditions: Ambient temp., dark, dry - Key result
- Surface tension:
- 63 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Conclusions:
- In the described surface tension test under the experimental conditions the results showed a surface tension > 60 mN/m. Therefore the test item has to
be regarded to be not surface active. - Executive summary:
The surface tension of Captan was determined according to EC method A.5 and OECD 115.
The mean surface tension of a 90 % saturated aqueous solution of Captan was determined as 63 mN/m at 20 °C.
The results showed a surface tension > 60 mN/m. Therefore the test item has to be regarded to be not surface active.
