  Ointment for summer weather

  Posted by YoungLia on September 4, 2016 at 2:26 pm

  Hi, 

  I am trying to make simple ointment in pilot scale. Like 10-25kg per batch.

  Ingredients:
  Petrolatum/ Petroleum jelly
  wax
  water soluble solids (quite a chunky granules)

  What would be the best way if I try not to use three roll mill? 
  My three roll mill is too slow (small capacity) and fiddly.

  Thanks in adv.

  Regards,
  Lia

  You need a cowles dissolver or similar high-speed, high-shear disperser if you can’t use a 3-roll mill:

  Anything else will be either nearly impossible to clean or extremely expensive - or both.
