Several methods are used to achieve suspension of salt/Sugar abrasives in the oil phase. In the following example, oils are gelled with thickening agents that impart yield value to the solution. It is the yield value that allows particles to remain in suspension. Fumed silica is one of the agents for gelling the oil phase. It should be noted that fumed silica is very light and dusty, and special protective measures should be taken by compounders. The use of ethylene copolymers is another methods form gets that break easily under shear stress, yet recover viscosity and yield quickly over time, which is to say they have thixotropic properties. As such they are considered a desirable medium for supporting and suspending particles in scrub formulations.The amount of fumed silica or ethylene copolymers varies according to oil type and the desired consistency of the final product.
Other oil thickening agents are quaternium-18 bentonites or stearalkonium bentonites, trihydroxystearin, and Rhns uerniciflua peel wax .These gelling agents also impart yield to the continuous phase and thus will Suspend salts or sugar .
Certain pre-made gels are also suitable for this application. One company offers several pre-made gels composed of mineral oil, ethylene/propylene/stylene copolymer and butylene/ethylene/ styrene copolymer Another Company's line has more than ten different pre-made gels that are oils thickened by bentonite derivatives.
consistency will vary with the amount of salt or sugar added to the formulation. The consistency can further be modified by incorporating surfactants into the system, which can improve both the viscosity, foaming or non foaming, and skin after-feel.
