SCA endorses products with the Toxic-Free Tick, that do not contain carbon black. If exposed to carbon black, the main concern is lung disease from inhaling carbon black particles that can irritate the lungs, causing coughing. It can also irritate the eyes, nose & throat, over many years the particles can lodge deep in the lungs. NHS states that “Scientists have found that “carbon nanotubes could pose a cancer risk similar to that of asbestos”, The Guardian reports. They are reported to be a similar in size and shape to certain asbestos particles.” - NHS. Classed as a skin, eye & lung irritant.
CAS No: 1333-86-4. Carbon Black; and "Synonym(s): CHANNEL BLACK; PIGMENT BLACK 6; PIGMENT BLACK 7; ACETYLENE BLACK; AROFLOW; AROGEN; AROTONE; AROVEL; ARROW; ATLANTIC; BLACK PEARLS " - EWG
HOW IS IT USED?
Carbon Black functions as a colourant; "composed of finely divided particles of elemental carbon obtained by the incomplete combustion of hydrocarbons (channel or impingement process)." - EWG
RESEARCH - WHAT DO THE EXPERTS SAY
WHAT IS CARBON BLACK?
NICNAS has No restrcitions on importing or use of this colourant that is banned in the US;
"Violation of government restrictions - Restricted in cosmetics; use, concentration, or manufacturing restrictions - Color additive not approved by FDA for cosmetics used around eyes (only for products for use around the eyes)" And, "Violation of government restrictions - Banned or found unsafe for use in cosmetics." CTFA International Cosmetic Ingredient Dictionary and Handbook. And, "Possible human carcinogenCalifornia EPA Proposition 65" - EWG
Toxicity Assessment "Results from reactive oxygen species (ROS) assay indicated that carbon black waste extract induced oxidative stress by increasing intracellular ROS generation in these three human cell lines. Moreover, induction of oxidative damage in these cells was also observed through the alteration of glutathione (GSH) and superoxide dismutase (SOD) activities. Last but not least, by treating the cells with V-spiked solution of concentration equivalent to that found in the carbon black waste extract, V was identified as the main culprit for the high toxicity of carbon black waste extract. These findings could potentially provide insight into the hazards of carbon black waste extract and its toxicity mechanism on human cell lines." - NCBI
