Shipped in a safety sealed wide mouth HDPE quart container with a resealable lid COUNTRY OF ORIGIN: U.S.A. SOURCE: lignite coal (a natural recurring source) METHOD: steam activation APPEARANCE: fine powder PHYSICAL STATE: solid COLOR: black ODOR: generally odorless, may produce slight sulfur smell when wet pH (water extract): 4.3 - 7.0 PARTICLE SIZE (laser): * d5, micron 2.7 min. * d50, micron 30 - 42 * d95, micron 130 max. CAS: 7440-44-0 SOLUBILITY: insoluble USES: Particularly suited for purification applications such as treatment of sugar solutions, corn syrups, and fine chemicals as well as decolorization, separation, deodorization, and catalyst. CAUTIONS: * Depletes oxygen from the air (especially when wet) and, therefore, dangerously low levels of oxygen could be encountered if area is not properly ventilated. * High surface area in activated carbons may cause self-heating during oxidation. * Do not create a dust cloud. * While difficult to ignite, it tends to burn slowly (smolder) without smoke or flame. INCOMPATIBLE MATERIALS: * strong acids * strong oxidizing agents High adsorptive capacity, good filterability, and above average purity. Well suited as an ingredient in soapmaking for clean, healthy skin, and in personal care products such as tooth powder and facial cleansers. Kosher and meets ANSI/NSF Standard 61.
