The ecological drugstore: Ecodis Extracted from natural quarries, mechanically refined, not calcined and without chemical transformation, the amorphous Diatomaceous Earth (silicon dioxide) is composed of very sharp microscopic marine algae fossils. Its biocide-insecticidal action is purely biological (strongly abrasive and drying), without side effects and is applied on many pests and crawling insects. Diatomaceous Earth is also used for animal care, as a household insecticide, for making paints and for housework. Ecological interest Extraction, production (mechanical refining without chemical transformation or heating) and packaging in Western Europe from almost inexhaustible quarries. Wide spectrum of uses. Packed in cardboard tube. Non-toxic for humans. Some technical characteristics - very fine powder of unheated whitish color, composed of 83% silicon dioxide SiO2 - absorbs 130% of its weight in water or oil - non-flammable, pH 8.5 INGREDIENTS Silicon dioxide (amorphous silica natural).
