Sooo…I had a jug of what I thought was HO sunflower oil in my pantry. To my surprise, it’s SAO that I’ve had since 12/2000. It smells absolutely fine and I wanted to use it to make scrubs. I assume it’s too late to add ROE. Is there anything I can do to possibly guarantee it’ll last like another 3-6 months or so?? I’m thinking I could use a short expiration date. Thoughts??
