Reference
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.
