Liquid Chlorophyll (Fresh Mint Flavor)

EU Cosmetics Regulation restricts methylparaben + ethylparaben to a combined 0.4% in cosmetics (single paraben) or 0.8% total. Methylparaben shows weak estrogenic activity in vitro (~10,000× weaker than estradiol, but additive with other parabens in mixed exposure). Darbre 2004 detected parabens in breast tumor tissue (mechanism uncertain). EFSA group ADI of 10 mg/kg/day for methyl + ethylparaben combined is conservative — typical supplement exposure is well below — but the additive is purely cosmetic and the paraben class is under sustained regulatory and consumer scrutiny. For supplements where a preservative is needed, lower-concern alternatives (potassium sorbate, sodium benzoate at low pH) are widely available.

EFSA Scientific Opinion (2004) withdrew the temporary group ADI for propylparaben and butylparaben because available toxicology data were inadequate to establish a no-observed-adverse-effect-level — propylparaben showed reproductive-toxicity signals in rat studies (decreased sperm/testosterone). EU Cosmetics Regulation banned propylparaben + isopropylparaben + butylparaben + isobutylparaben + pentylparaben from leave-on cosmetics in 2014. Estrogenic activity is ~1,000× weaker than estradiol but bioaccumulates in breast tissue (Darbre 2004, contested but real). FDA's 'safe at current usage' position has not been updated since EU's regulatory action. For a supplement excipient with purely preservative function, safer alternatives are widely available.
