Light cold particles, which quickly freeze water through a cascading effect.

Reactions

Freeze powder freezes water through a series of reactions. First, water is turned into freeze water:

+ →

Next, freeze water converts nearby water into more freeze water:

+ → 2×

Finally, freeze water solidifies into ice with ctype FRZW:

→

The resulting ice will get colder by itself, until it hits -273.15°C. Freeze powder also turns into such supercooling ice (marked with asterisk below) on contact with usual ice:
