Science & Benefits

A branched-chain fatty alcohol. Its branching makes it liquid at room temperature and enhances its ability to penetrate the skin. Unfortunately, this also makes it highly comedogenic (Rating 4). It is a stealth trigger in many 'oil-free' moisturizers that aim for a silky, non-tacky finish.
