Guest guest Posted March 14, 2003 Report Share Posted March 14, 2003 A high saving in time and energy can be achieved by heating the oil phase and 1/2 water phase of a lotion to 80 celsius and combining. Cool to about 60 celsius then add the remaining water at 25 celsius to cool down the lotion rapidly. This saves both time and energy in cooling with water jacket, and only needing to heat half the water. POE surfactants usually work well with this method, and every particular formula should be tested for stability. Probably not worth the bother when making below 1 tonne batches but thought it worth mentioning. Dave Eastham Quote Link to comment Share on other sites More sharing options...
