Cetyl Alcohol is a fatty alcohol that is derived from coconut and palm oils. (Just FYI, avoid this ingredient if you’re allergic or even slightly allergic to coconuts.) Far from drying, this alcohol is actually an emollient (makes hair and skin softer).
Stearyl Alcohol is another fatty alcohol that needs mention. It is nothing like ethanol, it is is actually a white solid and is insoluble in water. Stearyl alcohol is often used in conditioners and shampoos and acts as an emollient (softener).
Fatty alcohols provide an emollient effect, and bind water and oil to give hair conditioners their slip and creaminess.
Unfortunately, lots of people are sensitive (or believe themselves to be sensitive) to fatty alcohols and find them pore-clogging. Many acne-prone people would rather not take the chance doing skincare trial and error to find out if they’re truly sensitive and avoid all products with these ingredients.
