Hazelnut oil is another high oleic acid (66 to 85%) oil containing a little linoleic acid (up to 25%), a little palmitic acid (4 to 9%), and a little stearic acid (1 to 4%). It’s high in phytosterols – 1.2 to 1.4 grams per kg of oil – and Vitamin E (between 382 to 472...

Avocado oil (INCI: Persea gratissima (avocado) oil)contains a great deal of oleic acid (75 to 80%), and very little linoleic (7 to 10%), stearic (up to 4%), or palmitic (about 10%) fatty acids.
