I use EOs in mine, so it smells like them (rosemary and lavender are antiseptic, so help prolong it.) I'm not sure citric acid will preserve it very long--I use a combination of EOs, citric acid, Vit E and this time potassium sorbate. I freeze most of it and just defrost it in 4 oz, portions. Mine usually lasts a few weeks unrefrigerated. I only use it once a week.
