Someone gave me a lotion that I really liked. It was very emollient, not greasy, a nice lotion. I was curious about what emulsifier was used, so looked more carefully at the ingredients. They are as follows: Water, sunflower oil, glycerin, stearic acid, shea butter, lavender oil, collagen aminos, aloe vera juice, biotin, jojoba oil, some other oils, and the final ingredient was grapefruit seed extract. That's it, nothing else listed. I have never heard about just stearic acid being used as an emulsifier. Has anyone ever made lotion with just SA as an emulsifier? Is that possible that you know of?
