If you checked it for zap and there is no zap , you are good to go.I always try my soap out early if it doesn't zap. I can't wait I have to try it out. lol .
how much water did you use? if you used full water you may want to wait, they will melt quickly, otherwise you should be fine. as long as there's no zap.
I've used my CPOP soap the next day, but usually I like to wait 2 weeks and the soap is quite nice. Mildness and lather seem to increase the longer it cures, though.
