Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- 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)
- GLP compliance:
- no
- Type of method:
- plate method
- Specific details on test material used for the study:
- Name β-Alanine, N-coco alkyl derivs.
Batch no. LAB PREPARATION
Appearance Yellow Liquid
CAS No. 84812-94-2
Molecular formula H25C12NHCH2CH2COOH
Production date 01. Dec. 2017
Expiry date 01. Dec. 2022
Storage Room Temperature (20 ± 5 °C) - Key result
- Surface tension:
- 27 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 mg/L
- Conclusions:
- During a certain period of time, no significant changes in the surface tension were detected.
In dependence on time and temperature, values between 26.93 and 27.40 mN/m were recorded showing no significant variations. As the determined surface tension of β-Alanine, Ncoco alkyl derivs. was lower than 60 mN/m, the test substance can be classified as surface active.
