What is Coal-Tar Synthetic Dyes?
Coal-Tar Synthetic Dyes are artificial colorants derived from coal tar, a byproduct of coal processing. These dyes are manufactured through complex chemical reactions to produce vibrant colors used in a variety of industries.
These dyes are used primarily in cosmetics and personal care products to enhance visual appeal. The evidence surrounding their safety is mixed; some studies suggest potential health risks, such as allergic reactions or hyperactivity, although regulatory bodies consider certain dyes safe for use within specified limits.
When you see these dyes on a label, it may indicate the product has non-natural colorants. Checking product labels can help those who wish to avoid synthetic ingredients.

Scout's take
Blue 1 (triphenylmethane) + Yellow 5 (azo-tartrazine) added solely for color. Yellow 5 is a recognized contact sensitizer; both have documented dermal absorption.
