Ivy X Post-Contact Skin Cleanser is effective in assisting in the removal of poisonous plant oils (Urushiol) found in Poison Ivy, Poison Oak and Poison Sumac. Standard soap and water will not emulsify poisonous plant oils. Ivy X Post-Contact Skin Cleanser is designed to be “Wetter than Water” to start the emulsifying process to assist in removing plant oils before they have time to cause the uncomfortable rash, blisters and itching commonly associated with poisonous plants. Our packaging allows for a compliant and affordable skin protection program to help in poisonous plant protection.
