When to cap hair styling clay pomade?

After making my water based styling clay, and the final pour into containers, I notice that big companies place them in cooling racks.  I have a few questions...

1. How long are you suppose to leave them uncapped?

2. Do you refrigerate them?

I'm asking because I always get this firm top layer.  It's really annoying.  I typically place the jars in the coolest room in my house overnight then cap them in the morning.

  • Also, when I stir I get air bubbles.  Too much air...how do you minimize this?  Can I spray with alcohol?

    @KingRoland78 try to reduce the speed of stiring it helps to minimize bubbles.

    get them as cool as practically possible before filling them into containers, and put the caps on them straight away; this ensures any water loss (which causes the hard layer) is kept to a minimum

  • I use a small stick mixer and always have bubbles on top of my trials. Been trying to figure out to eliminate that from happening.
  • Proper mixing and time to settle with reduced speed mixing will eliminate most air bubbles. Moreover, bottom dispensing/filling will help as well... i.e. gravity drain on main vessel to containers being filled.
  • @justa_pinch @Bill_Toge caping my containers right after pouring really helped that firm top layer!! I actually used cheesecloth so it can breathe a little.  Still having issues with final product being kinda frothy with air.  Almost looks like i whipped up thick butter.
