Would it be ok to save mixed Blank Canvas (Pulp Riot) for the next day?

I’ve mixed Blank Canvas 1:4 with 10 volume developer; I only planned on applying it to half my hair today (I didn’t have enough time to apply to all my hair today), but there’s enough left over to cover the rest of my hair.

Would it be ok to cover the bowl with the remaining Blank Canvas with clingfilm and use it tomorrow?

(Sorry if it’s a silly question, it’s hard to find Blank Canvas so I don’t want to throw it away if it’s possible to use it tomorrow)
