Episode 16 — Dirty Thirty Chemicals: The Preservative You Can't Pronounce and Shouldn't TouchHey, welcome back to the Dirty Thirty at KeysPure.com. I'm Bob Root. Today's chemical wins the award for most unpronounceable name on the list: Iodopropynyl Butylcarbamate. Say that five times fast. Actually, don't — just stop buying products that contain it.This is a preservative found in a wide range of cosmetics and personal care products. Japan has already restricted it. And while it might not have the most extensive rap sheet on our list, what it does have is real cause for concern.Iodopropynyl Butylcarbamate is classified as a human toxicant. It's a possible liver and immune system toxin. It is significantly allergenic — meaning it can cause allergic reactions that range from mild irritation to serious sensitization. Once you develop a sensitivity to an allergen, it can persist for life.Preservatives in skincare are necessary — products need to stay stable and bacteria-free. But there is a difference between preserving your product and potentially sensitizing your immune system. At Keys, we find preservation solutions that protect the formula, not ones that put your health at risk.
