The Potassium Iodide Starch Test Paper is capable of detecting free Iodine, Chlorine, and Peroxides in solution. Lower concentrations of these substances will react with the strip at 5 - 10 ppm. This is utilized for qualitative testing in lab and industry settings. For instance, it can assess the amount of remaining chlorine in treated water. It is beneficial in water treatment facilities, environmental surveillance, and safety assurance.

This test paper is infused with potassium iodide and starch, and upon contact with an oxidizing agent, produces a blue-black complex. Iodine typically takes around 60 seconds to react, with initial reactions producing a subtle blue color. For higher concentrations, the strip will change from dark blue to purple.

Saved my skin barrier!!
I rarely write reviews, but this product truly deserves it. I have sensitive, dry skin with mild to moderate rosacea that became even more fragile after chemotherapy. While trying to repair my skin barrier, I overdid it with actives and completely wrecked my skin — it was red, raw, burning, and peeling. I turned to ChatGPT for help, and this Avene Cicalfate+ was one of the top recommendations. I started using it about three weeks ago, and wow — the difference is incredible! My skin has healed beautifully. The redness is dramatically reduced, the irritation is gone, and my skin feels soft, smooth, and calm again. The texture is soft and luxurious without being sticky. I love that there’s no noticeable scent, which is perfect for sensitive skin. It arrived well packaged and intact. For the results it delivers, I consider it an amazing value and will absolutely repurchase again and again. If you’re on the fence about trying this, go for it — it truly rescued and revived my skin barrier. This is now a permanent part of my routine and 100% a holy grail product for me!

Hydrating and Powerful Barrier Repair Serum!💧
This serum has been life-changing in calming and restoring my skin barrier. It absorbs quickly, feels lightweight, and instantly soothes irritation without feeling greasy. I’ve noticed my skin looks healthier and more balanced after just a few uses. It’s gentle enough for sensitive skin and works especially well when my skin barrier feels compromised. It is also fragrance-free, which I always appreciate! Trust me, it’s well worth the money!
