PurePath™ Banned Ingredient
Risk Level: 
High

Yellow 6

Chemical Identifier:
Yellow 6: Disodium 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonate.

☡Risk Level Summary☡

The "High" risk level is attributed to their status as behavioral neurotoxins and potent allergens. Unlike many other additives, Yellow 5 and 6 have a documented association with Hyperactivity (ADHD) and "behavioral outbursts" in children. Furthermore, they are frequently contaminated with known carcinogens such as benzidine and 4-aminobiphenyl during the manufacturing process.

Biological Impact & Mechanism

Historical & Common Use

Azo dyes were originally developed from coal tar in the mid-19th century. Yellow 5 and 6 were approved for food use in the early 20th century. Their use exploded in the 1950s as the "Technicolor" era of food began, allowing manufacturers to create neon-colored snacks that had never existed in nature.

Consumer Sentiments

Public sentiment is aggressively negative, especially among parents. The "Southampton Six" study (which included these dyes) sparked a massive global movement to ban synthetic colors. In the U.S., major brands like Kraft have been forced to remove these dyes from iconic products due to "mom-led" social media campaigns, leading to a market where "No Artificial Colors" is now a top-tier marketing claim.
