Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 30. Oct. 2019 (Study Plan dated); 06. Nov. 2019 (Experimental Starting Date); 06. Nov. 2019 (Experimental Completion Date)
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- Dated 27. July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- Commission Regulation (EC) No. 440/2008, from 30. May 2008, published on 31 May 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Preparation of the test material:
A solution of the test item containing 1.00 g/L in water HPLC grade was prepared. 0.1000 g of the test item was weighed into a 100 mL volumetric flask, dissolved in water HPLC grade using an ultrasonic bath then the flask was filled up to the mark with the water HPLC grade.
The Tyndall effect of the test solution was checked with a laser pointer, no Tyndall effect was visible - Key result
- Surface tension:
- 72.31 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of an aqueous solution of Ferric Choline Citrate was determined as 72.31 ± 0.08 mN/m at 20.0 °C. As the determined surface tension of the substance is higher than 60 mN/m, the substance can be classified as not surface active in a concentration of 1.00 g /L.

Measured Values Test Item First Series (see Table 8.2-a at page 11 of the attached full study report).
Measured Values Test Item Second Series (see Table 8.2 -b at page 11 of the attached full study report).
Description of key information
The surface tension of an aqueous solution of the substance (1 g/L) was determined as 72.31± 0.08 mN/m at 20.0 ºC.
Key value for chemical safety assessment
- Surface tension:
- 72.31
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
