Specific details on test material used for the study:
Name CARMINE LAKE
Batch no. HPFC16006A
Composition Hydrated aluminium chelate of carminic acid (7-beta-D-glucopyranosyl- 3,5,6,8-tetrahydroxy-1-methyl-9,10-dioxo-anthracene-2-carboxylic acid)
CAS No. 1390-65-4
Purity 55% Carmine
Expiry date 12. Apr. 2020
Storage Room Temperature (20 ± 5 °C); Keep away from light
Key result
Surface tension:
> 45.06 - < 51.35 mN/m
Temp.:
20 °C
Conc.:
236.9 mg/L
Conclusions:
Values between 45.06 and 51.35 mN/m of three measurement series were recorded. As the determined surface tension of CARMINE LAKE was lower than 60 mN/m. the test substance can be classified as surface active.
