Howdy folks-
Anyone know why a shaving soap burns? Too much fragrance/essential oil? Unconverted lye?

I've had a couple (Cirmes Sapera, _____ Dragon Blood) that burn quite a bit.
i added a couple of drops of veg oil to the mug & that boosted the lather, tho it still did dissipate quickly but did not cure the burn.

Any solutions to this?

thanks

Joe
