Potential carcinogen in animal studies; may affect thyroid function; restricted in some countries

A synthetic coal-tar/petroleum-derived dye used purely for color, linked to behavioral concerns in sensitive children. The lake form adds aluminum. No health benefit — we flag all artificial colors.

IARC classifies cosmetic-grade talc not containing asbestos as Group 2B (possibly carcinogenic to humans); perineal talc use as Group 2A (probably carcinogenic). Johnson & Johnson voluntarily withdrew talc-based baby powder from US/Canada in 2020 and globally in 2022 after extensive litigation tied to ovarian-cancer and mesothelioma cases. The 2018 FDA contamination survey found asbestos in 9 of 52 cosmetic talc products tested. As a supplement excipient talc is a pure manufacturing convenience — no nutritional or functional benefit to the user — so the asbestos-exposure risk has no offsetting upside. Safer alternatives (silicon dioxide, microcrystalline cellulose, rice hulls) are widely available.

Chassaing et al. 2015 (Nature, PMID 25731162) tested polysorbate 80 directly and showed it thinned the gut mucus barrier, altered microbiota composition, and induced low-grade inflammation and metabolic syndrome in mice. The strongest human evidence is for a related emulsifier rather than polysorbate 80 itself: Chassaing 2022 (Gastroenterology, PMID 34774538) was a controlled human feeding RCT of carboxymethylcellulose (CMC) that found microbial encroachment into the mucus layer — polysorbate 80 has not been tested in an equivalent human trial. In vitro work (e.g. Roberts 2010) shows polysorbate 80 enhances bacterial translocation across intestinal epithelium, and observational data link overall dietary-emulsifier exposure to IBD risk. EFSA is mid re-evaluation of polysorbates (E432–E436). For a supplement excipient with purely cosmetic function (improving the look/texture of soft gels and liquids), the gut-barrier risk profile is unfavorable when safer alternatives (sunflower lecithin, MCT carriers, gum acacia) are widely available.

Same petroleum-derived azo dye as Red 40, linked to hyperactivity in children (Southampton study) and carrying an EU warning label; pure cosmetic color with zero benefit.

Banned in the EU (2022) over concerns that its ultra-fine particles may damage DNA in gut cells. Still allowed in the US. Used only for white coloring — provides no health benefit.

May trigger sensitivity in some individuals; behavioral concerns in susceptible children
