ImerCare® 266D is a natural, medium-grind, diatomaceous earth (DE). DE is composed of siliceous fragments of fossilized skeletal remains of aquatic algae. Thanks to its micro-porous structure, ImerCare® 266D exhibits high absorbency power, resulting in a matt effect in make-up and a dry touch in emulsions. It also helps to accelerate the drying time of face masks. ImerCare® 266D is Cosmos approved.
