Ivy X Post-Contact Skin Cleanser assists in removing poisonous plant oils (Urushiol). Ivy X Post-Contact helps start the emulsifying process removing oils from poison ivy, poison oak, and poison sumac before they have time to irritate the skin and cause rashes and blisters. Simple soap and water will not wash away plant oils. Ivy X has been specially formulated to rid yourself of these harmful natural oils. In addition to using Ivy X Post-Contact Cleanser on your skin after exposure to harmful plants, Ivy X can also be added to the wash to aid in breaking down the oils that may attach to clothing or used to wipe down tools and other work gear that may have also come in contact with poisonous plants. Ivy X dries quickly and forms a barrier that doesn't wipe off or form clay-like caking on the skin like zinc-based products. Ivy X is easy to apply and is water- and sweat-resistant. To take the product off, simply wash with soap and water. This product is made in the U.S.A.
