Some of the symptoms that a person may experience if they are having an allergic reaction to this chemical can be very bothersome and uncomfortable. These would include changes in the color of their skin, headaches, pain in the stomach, congestion in the nasal passages, swelling in the face, feet, and hands, symptoms that appear to be asthma-like that may include wheezing and trouble breathing, hives, a skin rash, and itching.
