ImerCare® 03D is a high whiteness, natural diatomaceous earth (DE). DE is composed of siliceous fragments of fossilized skeletal remains of aquatic algae. Thanks to its micro-porous structure, ImerCare® 03D is designed for formulations requiring high absorbency power and matting. ImerCare® 03D’s fine grind means that it is particularly soft, making it ideal for make-up and foundation applications. ImerCare® 03D is Cosmos approved.
