Studies and research have been carried out to produce cosmetic emulsions that save time and energy to increase capacity and reduce the environmental impact. There are several issues to address, not least the fact that solid substances such as acids and fatty alcohols, waxes and esters are used in cosmetic emulsions that have to be liquified before emulsification and, once emulsified, re-solidified to bring the finished product to ambient temperature at the end of processing. An unsuitable production system, put into practice with the sole aim of reducing energy consumption, could create suspensions and fake emulsions.

Also, the rheological behavior of an emulsion during production, in particular if it is type WO, represents an obstacle that is difficult to overcome if you do not have an effective stirring system.

The objective of this work is to check whether it is possible to reduce the time and energy required for emulsion production without compromising the quality and stability of the finished product.

We seek to find a method that saves energy and increases production capacity with simple processing that can be performed in a normal production plant. In addition to avoiding damaging thermal stress to thermolabile substances, a low emulsification temperature limits odor and heat emissions, improving environmental and working conditions.
