Want to make your emulsion thicker, more creamy and stable?  Just add 1-2% of either: 

cetyl alcohol (cetanol (1-hexadecanol C16));

stearyl alcohol (1-octadecanol C18); or

cetostearyl alcohol (blend of C16 and C18).

I’m a huge fan of these common higher alcohols.  I use them in many product types including emulsions, hair conditioners, anhydrous balms/sticks.  They are inexpensive, widely available, “natural” and provide emolliency, viscosity build and stability. 

Let’s dig a little deeper….

Cetyl alcohol melts at 49.3°C and stearyl alcohol at 58°C.  Many formulators like to use a combination of both.  Making the alkyl distribution wider, by mixing the different chain lengths (C16 and C18) results in a more robust formulation, ability to cope with a wider range of temperatures, improved stability and ...
