Pifito Soap Making Oils Sampler - Castor Oil, Avocado Oil, Sunflower Oil (16 oz each) - Premium 100% Pure and Natural Carrier Oil for Essential Oils, Skin Care, Hair and Body Oil

I'm not exactly sure what the difference is between cosmetic grade and food grade, but from a cursory search, it seems that cosmetic grade oil is generally a lower grade of oil vs its food counterpart, and because of that, it's usually cheaper. I believe it also has to do with the extraction methods, as cosmetic grade oils can be extracted using solvents that should not be ingested, but would be fine for things like soap making. Anyways, I tested the smoke point of the avocado oil and sunflower oil, and I was pretty surprised to find that the avocado oil started smoking WAY below the expected smoke point of 500F as measured by my IR thermometer. It was smoking heavily starting around 300F. So, I'm not sure what to make of that. The sunflower oil smoked more or less at the expected temp. Regardless, I decided to use this for soap making.

A friend of ours has a soap making business, and she shows us how to make soap using lye and various oils, fragrances, essential oils, etc... We made a few bars of soap with the sunflower and avocado oil, and they came out well. I'll update the review as we gear up our soap making for the holidays, but so far, this has worked well.
