Benzyl Alcohol occurs in nature in many essential oils and plants, and it is used as an effective liquid preservative for skincare. So although it belongs to the alcohol family, its physical forms and properties are very different to say ethyl alcohol that we find in beer, wine and hand sanitisers for instance. When we say alcohol free, we are referring to common alcohol, which is used in cosmetics, but can cause reactions. Although benzyl alcohol is technically an alcohol, it is not classified as a drying or denatured alcohol like ethanol or isopropyl alcohol, which are commonly associated with skin irritation and dryness.
