I can't make any claims that this will be good for eczema, but I have been making successful bars using 20% palm, 20%coconut, and 60% olive oil pomace. You can always try subbing canola for the pomace (BUT DO RUN EVERYTHING THROUGH YOUR LYE CALCULATOR!), but I've been advised to use soaps with high soybean/canola/corn oil quickly once they have cured a minimum of 4 weeks because those types of oil go rancid quicker. So far the only bar of soap that I've made that has signs of going bad is one I did at 100% hydrogenated vegetable shortening (soybean/cottenseed oils). I have one bar I am keeping just to analyze and it started getting DOS around 2 months.
