Aqua, water, H2O, source of all life... in short, the fleet ;) Water is present in the vast majority of cosmetic products and often appears in the first position on the INCI list, meaning that it is the major constituent. Water plays an important role in your products. First, it allows you to make emulsions. Emulsions are mixtures of water and fat, one dispersed in the other in the form of fine droplets. All creams are emulsions, and it is the very process that gives them their pleasant texture. Water is also used to make gels, and overall, most liquid or pasty forms, except for oils, which are liquid, but do not contain water. In terms of sensory, water brings freshness, and avoids the shiny effects on the skin at the end of the application, which we tend to call a "greasy finish". Finally, water is an excellent solvent, and totally harmless to health. Given its high proportion in products, water is treated, and there are several types of water.
