Octyldodecanol is a branched-chain primary alcohol used as the isomer 2-octyl-1-dodecanol in cosmetics such as lipstick, [2] or as an anti-blooming agent in facepowder. [3] It is a medium spreading emollient, with equilibrium spreading pressure of 17.0 dyne/cm. [4] Octyldodecanol is in the class of Guerbet alcohols, because it has the branch at the β position. [5] Compared to arachidyl alcohol, the linear alcohol of the same molecular weight, it has a lower melting point, yet retains low volatility. [5]
2-Octyldodecanol is produced by the Guerbet condensation of decyl alcohol. [6]
When octyldodecanol is melted with an alkali it yields octyldodecanoic acid by a dehydrogenation reaction. [5]
