Short answer — according to Yuka’s “Top 10 Deodorants (US)” ranking, the deodorants with the highest Yuka scores are (top scorers first):

• Simply Unscented Deodorant — Humble — 100/100. (Yuka.io)
• Charcoal Deodorant (Scent Free) — Cleo + Coco — 100/100. (Yuka.io)
• Natural Deodorant — Hibar — 100/100. (Yuka.io)

Other highly rated deodorants in the same Yuka Top 10 (mostly 93/100) include Schmidt’s (Rose & Vanilla), Hello (Sweet Coconut), Every Man Jack (Sandalwood), Tom’s of Maine (Unscented), Curie (Coconut Nectar), Dr. Squatch (Fresh Falls) and Clean Age (Waves). (Yuka.io)

Notes and context

• Yuka publishes these “top” lists on their site/app and ranks products by availability and by their internal score; the Top 10 page I used was posted by Yuka (Feb 28, 2024). Scores and product rankings can change as Yuka updates entries or evaluates new formulations. (Yuka.io)
• Yuka’s cosmetic ratings are based on ingredient risk assessments; their help pages explain the selection and scoring process. If you want a live check for a specific deodorant (or the most up-to-date score), I can look it up now — tell me which product(s) you want checked and I’ll fetch current Yuka ratings. (help.Yuka.io)
