A promise to your customer: synthetic sapphire
The International Nomenclature of Cosmetics Ingredients (INCI) recently classified this particular type of aluminum oxide as “synthetic sapphire”.This allows cosmetics developers and marketers like you to add a notion of real luxury to your color cosmetics and personal care products and pass on a gemstone story or image to customers. You can let your imagination run freely with claims ranging from “Precious as a sapphire - white like snow” to “real gems add richness and beauty”. The ingredient may also be claimed as “alumina”.
RonaFlair® White Sapphire is the future of cosmetic fillers that add real luxury and functional properties to any cosmetic formulation.
