Application
Isopropyl palmitate is an emollient and moisturizer, it also acts as a binder and solvent. Similar to isopropyl myristate, it is produced from the combination of palmitic acid (coconut or palm oil) . enzymes are able to metabolize this ingredient and studies do not show allergic reactions or toxicity. Some sources indicate comedogenicity potential.
