Pantene Pro-V: SLES, 1,4-Dioxane, and the Preservative Europe Capped at 15 ppm
No banned actives here, but the sulfate that carries a probable carcinogen as a manufacturing byproduct is the lead ingredient, and the preservative system the EU restricted over a sensitization epidemic comes uncapped.
Pantene Pro-V Daily Moisture Renewal leads with sodium laureth sulfate, an ethoxylated surfactant that carries 1,4-dioxane (IARC Group 2B, EPA 'likely carcinogenic to humans') as a manufacturing byproduct that never appears on the label. The shampoo also contains MIT and MCI, the preservative system the EU capped at 15 ppm in rinse-off products after a wave of contact sensitization cases across Europe. Neither the 1,4-dioxane pathway nor the MIT concentration is limited by any federal US regulation.
The label, flagged
Water
Sodium Laureth SulfateCAUTION
The sulfate itself just cleans, the real issue is 1,4-dioxane, a probable carcinogen created when it's made, that never appears on the label.
Sodium Citrate
Cocamidopropyl BetaineCAUTION
Named Allergen of the Year in 2004, but the molecule isn't the culprit. A manufacturing impurity (DMAPA) is what sensitizes people.
Sodium Xylenesulfonate
Sodium Lauryl SulfateCAUTION
It does NOT cause cancer, that viral claim is a myth. What it actually does is strip and irritate skin, which matters if yours is reactive.
Sodium Chloride
FragranceCAUTION
Not a hazard in itself, but a legal black box. “Fragrance” can shield ingredients (including EU-banned ones) that you are never told are there.
Sodium Benzoate
Citric Acid
Tetrasodium EDTAACTUALLY FINE
A chelator that keeps formulas stable. It barely penetrates skin and carries no hazard finding. Cleared, though it does nudge other ingredients in slightly.
Panthenol
Stearyl Alcohol
emollient
Cetyl Alcohol
emollient
Polyquaternium-6
Guar Hydroxypropyltrimonium Chloride
Trihydroxystearin
Panthenyl Ethyl Ether
Histidine
MethylchloroisothiazolinoneCAUTION
A preservative the EU banned from all leave-on products after it triggered an allergy epidemic across Europe. Capped hard in rinse-off there; uncapped here.
