| What it is | The word alcohol on a label has cost this ingredient a lot of unearned suspicion. Cetearyl alcohol is a fatty alcohol — a waxy solid, closer to shea butter than to vodka — and it thickens and softens rather than dries. If a cream feels rich and stable, this is usually part of the reason. | The most effective occlusive in common cosmetic use, and the most unfairly maligned. Cosmetic-grade mineral oil is highly refined, chemically inert and rates as non-comedogenic in testing — the acne folklore comes from crude industrial grades, not from the ingredient in your cleansing oil. It hydrates nothing itself; it simply stops water leaving. |
