Cetyl Alcohol


CH3(CH2)14CH2OH. Also known as hexadecyl alcohol, cetyl alcohol is a saturated primary aliphatic alcohol. A colorless crystalline compound, it is insoluble in water and soluble in alcohol and ether. It has a melting point of 49.27°C and a boiling point of 344.0°C.

Compounds of cetyl alcohol are encountered in nature; for example, the cetyl alcohol ester of palmitic acid is the major component of spermaceti. In industry, cetyl alcohol is obtained, along with other higher alcohols, by the catalytic addition of carbon monoxide and hydrogen to olefins (hydroformylation or oxo process) with the subsequent reduction of the aldehydes produced to alcohols and by the hydrogenation of palmitic acid. It is used in cosmetics and as a starting material in the production of surfactants.

Increase in cetyl alcohol/amine ratio in DDA containing SLNs caused decrease in particle size (Figure 2), which could be because of the low miscibility of the DDA with cetyl alcohol, so that lower amounts of DDA had a lower negative effect of particle size leading to smaller particle size when its concentration is decreased in the SLNs (Figure 2).
The following discussion will be limited to costabilizers, such as hexadecane, which are not present at the interface and do not exhibit substantial interactions with the surfactant at the interface (as cetyl alcohol).
