Synthetic fluorphlogopite, more widely referred to as synthetic mica, is a shimmering powder made of tiny sparkling flakes.
What is SYNTHETIC FLUORPHLOGOPITE used for?
Synthetic fluorphlogopite is used to add sparkling effect in leave-on products and rinse-off products such as face powders, bath soaps, lipsticks, eye makeup products, blushers, highlighters, shampoos, body washes, cleansers, lip & cheek tint.
Origin
A reported manufacturing method of synthetic fluorphlogopite designed for industrial scale batches involved melting oxide–fluoride mixtures (metal, i.e., aluminum and manganese) at a given “soak” temperature (wherein the contents are liquid; up to 1,450°C) and then cooling at a continuous rate of a few degrees per hour between 1,400°C and 1,300°C. This technique produced large fluorphlogopite monocrystals (several centimeters). An alternate method synthesized fluorphlogopite single crystals, several millimeters in size, suited to laboratory uses. A mixture of SiO2, γ-Al2O2, MgO, and K2SiF6 was melted at 1,450°C for 3 hours, cooled to 1,385°C at a rate of 100°C/h, and then quenched into cold water. The resulting charge was loaded back into the furnace, heated from ∼1,000°C to 1,385°C at a rate of 500°C/h, and finally cooled at a rate of 1°C/h down to 1,300°C. This procedure led to the formation of large and detachable monocrystals of synthetic fluorphlogopite up to 1 cm in diameter.
