Coal Tar Dyes
Colours, Bleaching & Hair Dyes. SCA endorses products with the Allergy Certified logo, that restrict the use of synthetic colours to a maximum of 1% or less for leave on-products and a maximum of 2.5% or less for wash-off products. Colour additives should also require a warning on the product label to "always patch test before use" and "discontinue use if irritation occurs". Where a brand tests their products and/or the ingredient of concern is tested for carcinogenic contaminants, test reports confirming that the product and/or ingredients are free-from carcinogens can be submitted; SCA will endorse the product(s) containing toxic-free coal tar dyes.

WHAT ARE COAL TAR DYES?
Synthetic colours. FD&C or D&C artificial colours are derived from coal tar or petroleum. Synthetic colors are suspected to be a human carcinogen, a skin irritant and are linked to ADHD in children. Dyes are not pure chemicals and may contain upwards of 10% impurities.
Many artificial food colours are derivatives of petrochemicals and coal tar. Coloring agents blue 1, blue 2, yellow 5, and yellow 6 are banned in the EU. Dyes are manufactured as powders, granules or liquids. They are used as a colouring agent in food, cosmetics and other household products.
Studies show that long-term exposure to artificial dyes can cause cancer or other effects.
