Bovine Spongiform Encephalopathy

In speaking with Dr. Ermias Belay of the Center for Disease Control (CDC) in Atlanta, the transmission of Bovine Spongiform Encephalopathy (BSE) is still under investigation. Currently, the most accepted theory is that transmission occurs through a prion protein that has been genetically altered through an anomaly of chromosome #20. Bone charcoal and bone ash are derived from bones which are de-fatted, de-tallowed, and devoid of tissue. This leaves only bone material which is hydroxyapatite or tricalcium phosphate. This material is then placed into retort kilns and burned at temperatures reaching 1000o C for 12 hours. This temperature will denature any protein, therefore the risk of BSE in these products are non-existent.

Specified Risk Material Removed Certification

Bone Black Pigments are manufactured only from crushed cattle bones that are sourced from countries that are declared free from Bovine Spongiform Encephalopathy (BSE) by the United States Department of Agriculture (USDA). These countries are India, Pakistan and Nigeria. Prior to shipment, all the cattle bones have the Specified Risk Material (SRM) removed and all shipments used to manufacture the Bone Black Pigments have governmental documentation attesting to this.

CONEG and Proposition 65 Requirements

In order to comply with the requirements mandated by the Coalition of New England Governors (CONEG), the State of New Jersey Community Right-to-Know Act, and California's Proposition 65 legislation, the Ebonex Corporation certifies that the Cosmic Bone Black pigment and charcoal it provides contains less than the total concentration of Cadmium, Hexavalent Chromium, Lead and Mercury of 100ppm.

The results measured by ICP (Inductively Coupled Plasma) are as follows:

Cadmium  =  0.082ppm
Chromium (hex)  =  0.290ppm
Lead  =  2.305ppm
Mercury  =  0.050ppm

Hazardous Air Pollutant (HAP)

The 1990 Clean Air Act directs the EPA to regulate emissions into the air of 189 toxic chemicals known as Hazardous Air Pollutants(HAPs) which are known or suspected carcinogens. Bone Black pigments are not contained on the list of Hazardous Air Pollutant (HAP) section 112(b)(1) set forth by the 1990 Clean Air Act.


Bone Blacks are non-hazardous, and are Generally Regarded As Safe (GRAS) by the FDA (Food and Drug Administration) for indirect food contact applications provided they meet specifications under CFR 175.300(b)(1), CFR 174.5(d)(1), CFR 182.1217, and CFR 182.8217 set forth by the Food Chemical Codex.
