Soap Allergy and Detective Work
I have broken out from 3 shave soaps. Geo F Trumpers, C&E Moroccan Myrrh and this morning L'Occitane Cade. Oddly enough, I have used Cade several times before without an issue, but this morning it left my face with a rash -- red, hot and painful. My face still looks wind burnt over 12 hours later.
So I put together a spreadsheet with the ingredient lists for all the soaps I have used. Including those that have / have not caused me to break out. The ingredient that stands out is Sodium Palmate (product of palm oil / Lye). It is a top ingredient in all three of the problem soaps and is not present in any of the other soaps. Oddly enough Sodium Palm Kernelate (product of Palm Kernel Oil / lye) is in several of the products that do not cause an issue.
So apparently, I have an allergy to soaps that use Palm Oil in the saponification process. That rules out a lot of the hard soaps. Kinda bummed.
