Summary
There are two categories of cleansing scrubs, aqueous and nonaqueous. Water - insoluble abrasives are used in aqueous-based scrubs. Hardness, shape and particle size are three critical factors for evaluation of abrasives. The most appropriate hardness range is from 0.5 to 7.0 The most appropriate shape is spherical and the best size ranges from 40- 80 Mesh ( 180 to 420 Microns). Gel -like, paste- like and cream ( emulsion)-like solution are three different types of aqueous formulas wherein abrasives are varied from 0.5%to10%
In contrast to traditional aqueous scrubs, nonaqueous- based scrubs are focused on cleansing, conditioning and treating skin at the same time. Oits, glycols and silicone oils are three possible continuous phases in the continuous phase, giving better performance in application. The abrasives normally used in these scrubs are salt and sugar. They can be suspended or allowed to settle to the bottom of the hardness, size and shape of abrasives are paramount factors in determining scrub performance. The most preferred sizes range from 20-80 Mesh. The cubic (more regular) shapes are preferred for less abrasive skin-feel. Skin benefits stem from both the Continuous phases and abrasives.
