From the manufacturer's website:
Ban® Invisible Solid Unscented Deodorant has the same strong wetness and odor protection, all while going onto skin clear. With odor-fighting ingredients and Kihada extract, our scentless deodorant offers 24-hour odor protection. The formula eliminates odor causes by bacteria breaking down sweat on the surface of your skin. If you want a deodorant without the strong fragrances or white streaks, reach for Ban® Unscented Invisible Solid.
Ban® is famous for our roll-on deodorants, but we also offer the classic solid deodorant as well. Our Invisible Solid may surprise you. It looks white, but glides onto skin clear and dry. It also has less residue than our original solid. That means you don’t have to worry about it rubbing off onto your clothing or skin.
Warning: For external use only. Do not use on broken skin. Stop use if rash or irritation occurs. Ask a doctor before use if you have kidney disease. Keep out of reach of children. If swallowed, get medical help or contact a Poison Control Center right away.

Recommended use: Apply our clear unscented stick deodorant to clean, dry underarms. Swipe deodorant to your underarms using 2-3 upward and downward sweeps. This technique helps ensure you’re covering all of your sweat glands. If you have hair in your armpits, you may need to apply more pressure when putting on deodorant. Experiment with how much you apply and at what time of day to figure out what works best for your body.
