Old Spice High Endurance: 1 Ingredient Banned in EU by 2027, 1 Flagged for Endocrine Effects
The cyclopentasiloxane carrier the EU is phasing out sits right behind the active, and the only reason it is still legal here is that the US never passed the regulation.
Old Spice High Endurance Pure Sport is a classic stick antiperspirant, aluminum zirconium works, the EU cleared the active on human health, and most of what is in the base is genuinely boring chemistry. Two ingredients are worth knowing about: the cyclopentasiloxane carrier is being phased out of all EU cosmetics by June 2027 for environmental persistence, and the formula for some SKUs contains BHT, which the EU has flagged for potential endocrine effects and the UK formally restricted in 2024. Neither is a crisis at this product's concentration levels, but here is the full label.
The label, flagged
Aluminum Zirconium Tetrachlorohydrex Gly 17%ACTUALLY FINE
The most fearmongered ingredient in your bathroom, and the EU's own scientists found no reliable link to breast cancer or Alzheimer's. We clear it.
active
CyclopentasiloxaneCAUTION
Being phased out across the EU by 2027, but for the planet, not your body. The SCCS judged it safe for human health; the restriction is environmental.
Stearyl Alcohol
wax/emollient
Mineral Oil
Dimethicone
Petrolatum
Hydrogenated Castor Oil
Kaolin
PPG-14 Butyl EtherACTUALLY FINE
An emollient carrier with a clean CIR safety review and no EU or US restriction. Boring, and that's the point, not everything on a label is a villain.
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.
Behenyl Alcohol

What to use instead
The fix isn’t complicated: a fragrance-free or fully-disclosed alternative, with the ingredients flagged on this label designed out, closes these gaps at once. We pick the ones worth your money.
