Summary

Sunset Yellow FCF, also known as Yellow 6, is a synthetic food coloring widely used to provide an orange-yellow hue to various food products, drugs, and cosmetics [5], [14], [23], [24]. It is derived from petroleum and is categorized as an azo dye [16], [26].

What it is

Sunset Yellow FCF is a synthetic colorant that belongs to the family of azo dyes [5], [23]. It is primarily the disodium salt of 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid [24], [25].

Common uses

Candy [16], [18], [19]
Snack foods [16], [18], [19]
Baked goods [24]
Beverages [16], [18], [19]
Dessert powders [24]
Cosmetics [14], [24]
Drugs [14], [24]

Public Perception

Anxiety level

High, due to concerns about potential health effects, particularly hyperactivity in children, allergic reactions, and the presence of potentially carcinogenic contaminants [16], [17], [18], [19], [20], [21], [22].

Cultural claims

Some advocate for the removal of artificial dyes due to potential risks, especially to children [16], [18], [19].
There are concerns about the lack of nutritional value and potential harm caused by artificial dyes [16].

Source sentiment

Generally negative, reflecting concerns about potential health risks, especially regarding hyperactivity in children and allergic reactions [16], [17], [18], [19], [20], [21], [22].

History

Timeline

1929

First listing of FD&C Yellow No. 6 for food use [14].

1939

Approved for use in food, drugs, and cosmetics [14].

1986

Permanently listed for use in food, drugs, and cosmetics [14], [24].

2014

EFSA sets Acceptable Daily Intake (ADI) of 4 mg/kg bw/day for Sunset Yellow FCF [8], [9].

2025

The FDA and HHS announced a plan to phase out petroleum-based synthetic dyes from the American food supply [16], [18], [19], [22].

Origin

To provide stable and uniform coloring to food products [5], [17].

Science

Key findings

Some studies suggest a link between Sunset Yellow FCF and hyperactivity in children [16], [17], [20], [21].
Sunset Yellow FCF may trigger allergic reactions in some individuals [17], [28].
Chronic consumption of Sunset Yellow may cause gut dysbiosis and alter gut integrity in rats [7].
Studies indicate potential neurotoxic effects, including oxidative stress and neurotransmitter imbalances [5], [6].

Studies

Assessment of FD&C Yellow No. 6 (Sunset Yellow FCF) effects on sperm count, motility and viability in the rat in a 28-day toxicity study

No adverse effects on sperm quality parameters were observed in male rats at intake levels up to 1,475 mg/kg bw/day [11].

Sunset Yellow dye effects on gut microbiota, intestinal integrity, and the induction of inflammasomopathy with pyroptotic signaling in male Wistar rats

Chronic oral consumption of Sunset Yellow in rats causes gut dysbiosis, reduces beneficial taxa, increases potentially pathogenic microorganisms, reduces jejunal adherens and tight junctions, and triggers intestinal inflammasomopathy and pyroptotic cell death [7].

Biochemical processes mediating neurotoxicity induced by synthetic food dyes: A review of current evidence

Synthetic food dyes, including Sunset Yellow FCF, can significantly impact brain function and overall neurological health by affecting oxidative stress, neurotransmitter imbalances, mitochondrial dysfunction, and inflammatory responses [5], [6].

Determination of the effect of sunset yellow on the morphological parameters of male mice during the development period

Sunset Yellow administration during childhood caused retardation in growth and development parameters in mice [12].

Safety status

Sunset Yellow FCF is generally considered safe within the established ADI (Acceptable Daily Intake) by regulatory bodies like the FDA and EFSA [8], [9], [14], [24]. However, concerns persist regarding potential adverse effects, especially in sensitive individuals and children [16], [17], [18], [19], [20], [21], [22].

Nuance

While regulatory bodies have established acceptable daily intake levels, some studies suggest potential adverse effects, particularly concerning hyperactivity in children and gut health. More research is needed to fully understand the long-term impacts of Sunset Yellow FCF consumption [5], [6], [7], [8], [9], [11], [12].

Avoidance tips

Read food labels carefully to identify products containing Sunset Yellow FCF (Yellow 6 or E110) [27], [31].
Choose products with natural coloring agents instead of synthetic dyes [27], [31].
Monitor children's consumption of artificially colored foods [27], [31].
