This is the ferulic acid molecule as I couldn’t find one for rice bran oil! Rice bran oil (INCI: Oryza Sativa (Rice) Bran Oil) contains 16% palmitic acid, 2% stearic acid, 42% oleic acid (C18:1), 36.6% linoleic acid (C18:2), and 1.5% linolenic acid (C18:3). It contains tocopherols at 400 mg per kg of oil, which...
This is a squalene molecule – note the “-ene” at the end indicating it contains double bonds. It’s found in rice bran, olive, and wheat germ oil, as well as shark’s livers! (Make sure the squalene you buy comes from olive oil and not shark livers – it’s unlikely you’ll encounter this problem, but double...
Oleic acid (C18:1) is another fatty acid that shows up a lot in the oils we use in lotion making. It is found in olive oil at really high rates (78%) and high oleic sunflower oil (74%). It has only the one double bond, so it has a longer shelf life than those oils with...
Polyphenols are found in oils and other botanical ingredients in five major categories… phenolic acids, the derivatives of hydroxycinnamic acid and hydroxybenzoic acid hydroxycinnamic acid – caffeic acid, ferulic acid, p-coumaric acid hydroxybenzoic acid – vanillic acid, syringic acid, gallic acid flavonoids, which include flavones, flavonols, flavanols, flavanone, isoflavones, and anthocyanins (but not Flavour Flav,...
