1-Hydroxyoctadecane
1-Hydroxyoctadecane (Stearyl alcohol) is a long-chain fatty alcohol and excipient. 1-Hydroxyoctadecane forms a closed oil film, thereby reducing transepidermal water loss (TEWL) and promoting skin moisturization. 1-Hydroxyoctadecane improves Imiquimod (HY-B0180)-induced psoriatic skin inflammation in mice[1].
