SPRAY/WIPE & SERUM EMULSIONS
Concentrated emulsion technology for spray, wipe concepts
Thin liquid oil-in-water emulsions with very small droplet sizes of 0.3 μm can be obtained when producing via a simple intermediate concentrated oil-in-glycerin (O/G) emulsification step. The O/G emulsion is then diluted with water to a final spray or wipe formulation. Applications such as baby wipes and spray formulations are easily achieved.
Both hot and cold productions are possible when working via the concentrated emulsification step, creating the most optimum spray/wipe emulsions with respect to stability, viscosity and energy input.
Effective serum formulations
Due to the very small droplet sizes of 0.3 μm, this is also an excellent production method for making serums with a high skin penetration. Serums can require a higher viscosity than the spray and wipe concepts, which can be achieved by selecting the right production process (hot or cold), sucrose ester grade and hydrocolloids.
