Bismuth Oxychloride - This ingredient is not used in Skin Rich mineral makeup however it is used in mineral makeup as a ‘filler’.

Itcan cause breakouts and irritation. Serecite is the most naturalreplacement however some are replacing it with boron nitrate/nitrite,which falls into the category of magnesium stearate, as it moves awayfrom being a pure mineral and undergoes processing.

Dimethicone/Methicone/Cyclomethicone - These ingredients are not used in Skin Rich mineral makeup. Theyare all minerals, however they are derived from silicone (cosmeticsilicone) which are synthetic. They add a creamy texture toformulations, however they can irritate sensitive skins.

Rice Powder - This ingredient is not used in Skin Rich formulations. It is anaturally occurring soft powder often used in place of talcum with amedium absorbancy.

We choose to use kaolin clay as a much more cosmetically accepted ingredient with far more mineral content.

Magnesium stearate, stearic acid and calcium stearate, made by hydrogenating cottonseed or palm oil, are used throughout the supplements industry as lubricants. They are added to the raw materials in supplements so that production machinery will run at maximum speeds. These fatty substances coat every particle of the nutrients, so the particles will flow rapidly. This ensures that production schedules will meet profit targets.

Cottonseed oil has the highest content of pesticide residues of all commercial oils; cotton crops are heavily sprayed. In the hydrogenation process, the oil is subjected to high heat and pressure in the presence of a metal catalyst for several hours, creating a hydrogenated saturated fat. Hydrogenated vegetable fats contain altered molecules derived from fatty acids that may be toxic. The metal catalyst used in the hydrogenation process may also contaminate the stearates produced (see Erasmus, Fats and Oils).

While toxicity is one problem, decreased absorption is another. In a study published in the journal Pharmaceutical Technology, the percent dissolution for capsules after 20 minutes in solution went from 90% without stearates to 25% with stearates (article available from us upon request). This delays the absorption of nutrients. Individuals with impaired digestion may have particular difficulty absorbing nutrients coated with stearates.

Another problem with stearates: concentrated doses of stearic acid suppress the action of T-cells, a key component of the immune system. The article "Molecular basis for the immunosuppressive action of stearic acid on T cells" appeared in the journal Immumology in 1990
