I have read online via this site and others that this ingredient can be good and bad. From my personal experience, each product that I have used with this ingredient has worked extremely well in my hair. I think it is because Isopropyl Myristate absorbs so well. The products I have used with it are Hollywood Olive Creme, Optimum Oil Therapy Hair Quencher (second ingredient in both products), and most recently, I have been sealing my Nexxus Humectress with Apoghee Essential Oils, which also contains the ingredient. Anybody else like Isopropyl Myristate?
