Thanks for your replies. I've only done M&P soaping myself, but would like to make soap from scratch so bought some homemade ones to try out & compare.
I'm not sure if it was CP or HP, but the soap had a label saying it was made end of June. Ingredients were coconut, sunflower, canola, flax seed, castor oils, goats milk & lye. The smell is hard to describe, but is acidic & definitely smells burnt - almost chemical, like burnt plastic.
Should I throw it out? I def won't be using it on my face or on my baby, which is what I wanted it for!
