soy bean oil. It's not a sexy oil or one that's trending in beauty products, but it's one of the most inexpensive ones you can find and it's packed full of all kinds of neat stuff, like tocopherols (anti-oxidants), phytosterols, and isoflavones in addition to its awesome fatty acids, like linoleic acid.
The phytosterols in soy bean oil can help reduce inflammation and restore skin's barrier mechanisms. The isoflavones behave as anti-oxidants and help soften skin. And the linoleic acid helps restore barrier function and reduces scaling on your skin. This oil will offer your skin lots of lovely moisturizing and softening with some anti-oxidants and anti-inflammatories as well. It has a shelf life of up to a year with a light and greasy feeling. I've seen it listed as being medium to high comedogenicity, but as I've said before, these scales aren't that accurate and you have to try things to see how your skin reacts.
All of this awesome for the low low price of $9 or so per litre (33 ounces)! Per litre! To put this in perspective, it's about $8 for 2 ounces/60 ml of evening primrose oil, $12 for 4 ounces/120 ml of meadowfoam seed oil, $12 for 2 ounces/60 ml of pomegranate oil, or $12 for 2 ounces/60 ml of sea buckthorn oil. Rice bran oil is around $15 per litre and sweet almond oil is about $14 per litre, so even within the range of carrier oils, it's still inexpensive.
anhydrous or non-water containing products like a facial serum, whipped butter, or lotion bar, to give a few examples - or in products that contain emulsifiers, like facial moisturizers, lotions, or hair conditioners. It's a fabulous addition to any product intended to moisturize and soften skin. I absolutely love it in my winter body butters because it can help speed up skin's barrier mechanism repair or this winter hand protectant lotion. I love it in this six ingredient lotion, and I think it's awesome in this emulsified sugar scrub! It would be fabulous in this make-up remover, and a great substitute for the rice bran oil in this hand lotion.
I love soy bean oil and have tried it in every product I make with oils. It is a little greasy feeling, so if you really hate that sensation, this oil probably isn't for you. If you like sunflower oil or pumpkin seed oil, you should like soy bean oil.
