Speed Stick Power Fresh Antiperspirant
Summary
Speed Stick Power Fresh scores 17/100. Colgate-Palmolive's mainstream antiperspirant for men, with aluminum zirconium tetrachlorohydrex GLY 15.9% as the active (standard sweat-duct blocker, systemic absorption concern). The supporting cast: cyclopentasiloxane (D5 silicone, EU vPvB-flagged), PPG-14 butyl ether, PEG-8 distearate (1,4-dioxane risk), C12-15 alkyl benzoate, hydrogenated castor oil, and synthetic fragrance with no allergen disclosure. Slight bumps for real palm kernel oil and hydrogenated soybean oil as fats. Includes pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate, a synthetic phenolic antioxidant similar to BHT.
