Key value for chemical safety assessment

Surface tension:
71.1
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

Based on REACH Regulation (EC n. 1907/2006), annex VII, column 2 the study need only be conducted if:

— based on structure, surface activity is expected or can be predicted, or

— surface activity is a desired property of the material.

Calcium Hypophosphite is inorganic and ionic. There is no hydrophobic moiety and cannot have surfactant properties. Surface property is absolutely not a desired property of the material.
