I have started making soap using lye with the Cold process method, meaning I mix the lye in water then combine with oils to make soap. I take great care with safety, goggles, gloves etc, but I have started to notice swelling in my legs and feet and sometime urine incontinence. I bought a respirator because I thought it might be some of the fragrance oils I use, but I made soap 2 days ago after a 2 week break with no fragrance and I got the swelling again. Could this be an allergy to Lye? Should I wear the respirator all the time and see if it occurs again? Please help, this is my new hobby after breast cancer and I do not want to give it up as I started it to make natural products for myself. Thank you very much.
