Oil- based scrubs: Oils include natural ester oils, Mineral oil and synthetic oil. Some of the natural oils included are shown in Table3. Most of those oils are triglycerides,which deliver good skin feel, moisturization and skin protection.
One problem with natural oils is their tendency to become rancid. AntiOxidizing agents such as tocopherol (vitamin E),BHT Cbutylated hydroxytoluene) or benzotriazolyldodecyl p-cresol are necessary to prevent rancidity. In addition, winterized natural oils are preferred to prevent temperature-related redimentation.
In Oil scrub formulas that carry salt/sugar abrasives, the total amount of oil is 25% to 40%, with corresponding salt/sugar levels of 60% to 75%. the Specific gravity of these particles is higher than oit; thus, they will sink to the bottom of the container when immersed in oil. When this Occurs, the overall product will present with two distinct phases.
There are some limitations When employing natural oils in salt and sugar scrubs. Changing the color of the oil phase is difficult because most natural oils have a yellow or green- yellow hue. In addition, natural oils do not spread easily across surfaces. Therefore the spreadability of natural oils comes into play and is normally represented in terms of viscosity. Light natural oils (low Viscosity)are preferred to heavy natural oils (high viscosity) because they are easier to spread across the skin surface and do not leave a heavy feel. The preferred viscosity range of oil or oil blends is 50 -200 cps. It is the unfor ternate Case, however, that natural oils (except sunflower oil and Safflower oil) Show moderate comedogenicity.
