Octyldodecanol is a widely used ingredient in cosmetics, personal care, and skincare formulations. Depending on its function, it may serve as a moisturizer, preservative, emulsifier, or active ingredient to enhance the overall effectiveness and performance of a product.
Octyldodecanol is a branched-chain primary alcohol used as the isomer 2-octyl-1-dodecanol in cosmetics such as lipstick, or as an anti-blooming agent in facepowder. It is a medium spreading emollient, with equilibrium spreading pressure of 17.0 dyne/cm. Octyldodecanol is in the class of Guerbet alcohols, because it has the branch at the β position. Compared to arachidyl alcohol, the linear alcohol of the same molecular weight, it has a lower melting point, yet retains low volatility.
