This clay is used to adjust rheological properties and to stabilize emulsions and suspensions.
When it is part of the cosmetic industrial formulation, which generally includes surfactant molecules, perfumes, and antioxidants, among others, it is expected that the clay undergoes some type of chemical modification – especially when it is a liquid or pasty product in which the clay is in suspension.
Brazilian Kimberlite Clay is used to stabilize oil emulsions in water in creamy products. Its role is to remain as a protector between the two emulsion phases. It is used as a rheological agent in this type of emulsion, mainly because it can be wet by both liquid phases. It acts as a physical
barrier by preventing the coalescence of liquid emulsion drops and by stopping phases from separating.
