Chemical Properties

Chemical Properties

white solid

Chemical Properties

Cetyl alcohol occurs as waxy, white flakes, granules, cubes, or castings. It has a faint characteristic odor and bland taste.


Reported as a major constituent of spermaceti oil, where it is present chiefy as cetyl palmitate Also reported found in guava, peach, pear, kohlrabi, baked potato, mustard, Parmesan cheese, butter, milk powder, boiled egg, cooked chicken, roasted beef, beef fat, whiskies, tea, starfruit, mango, rice, licorice, kiwifruit, loquat, endive, shrimp, crab, clam, Cape gooseberry and pawpaw


Pharmaceutic aid (emulsifying and stiffening agent).


cetyl alcohol is a versatile ingredient that can serve as an emollient, emulsifier, thickener, binder, foam booster, or emulsion stabilizer, depending on the formulation and need. It is derived from coconut or palm oil as well as being synthetically manufactured. It is considered by some sources to be a non-comedogenic material.


ChEBI: A long chain fatty alcohol that is hexadecane substituted by a hydroxy group at position 1.

Production Methods

Cetyl alcohol may be manufactured by a number of methods such as esterification and hydrogenolysis of fatty acids or by catalytic hydrogenation of the triglycerides obtained from coconut oil or tallow. Cetyl alcohol may be purified by crystallization and distillation.

Pharmaceutical Applications

Cetyl alcohol is widely used in cosmetics and pharmaceutical formulations such as suppositories, modified-release solid dosage forms, emulsions, lotions, creams, and ointments.
In suppositories cetyl alcohol is used to raise the melting point of the base, and in modified-release dosage forms it may be used to form a permeable barrier coating. In lotions, creams, and ointments cetyl alcohol is used because of its emollient, water-absorptive, and emulsifying properties. It enhances stability, improves texture, and increases consistency. The emollient properties are due to absorption and retention of cetyl alcohol in the epidermis, where it lubricates and softens the skin while imparting a characteristic ‘velvety’ texture.
Cetyl alcohol is also used for its water absorption properties in water-in-oil emulsions. For example, a mixture of petrolatum and cetyl alcohol (19 : 1) will absorb 40–50% of its weight of water. Cetyl alcohol acts as a weak emulsifier of the water-in-oil type, thus allowing a reduction of the quantity of other emulsifying agents used in a formulation. Cetyl alcohol has also been reported to increase the consistency of water-in-oil emulsions.
In oil-in-water emulsions, cetyl alcohol is reported to improve stability by combining with the water-soluble emulsifying agent. The combined mixed emulsifier produces a close packed, monomolecular barrier at the oil–water interface which forms a mechanical barrier against droplet coalescence.
In semisolid emulsions, excess cetyl alcohol combines with the aqueous emulsifier solution to form a viscoelastic continuous phase that imparts semisolid properties to the emulsion and also prevents droplet coalescence. Therefore, cetyl alcohol is sometimes referred to as a ‘consistency improver’ or a ‘bodying agent’, although it may be necessary to mix cetyl alcohol with a hydrophilic emulsifier to impart this property.
It should be noted that pure or pharmacopeial grades of cetyl alcohol may not form stable semisolid emulsions and may not show the same physical properties as grades of cetyl alcohol that contain significant amounts of other similar alcohols.


Cetyl alcohol is mainly used in topical formulations, although it has also been used in oral and rectal preparations.
Cetyl alcohol has been associated with allergic delayed-type hypersensitivity reactions in patients with stasis dermatitis. Crosssensitization with cetostearyl alcohol, lanolin, and stearyl alcohol has also been reported. It has been suggested that hypersensitivity may be caused by impurities in commercial grades of cetyl alcohol since highly refined cetyl alcohol (99.5%) has not been associated with hypersensitivity reactions.
LD50 (mouse, IP): 1.6 g/kg
LD50 (mouse, oral): 3.2 g/kg
LD50 (rat, IP): 1.6 g/kg
LD50 (rat, oral): 5 g/kg


Cetyl alcohol is stable in the presence of acids, alkalis, light, and air; it does not become rancid. It should be stored in a well-closed container in a cool, dry place.

Purification Methods

Crystallise the alcohol from aqueous EtOH or from cyclohexane. Alternatively purify it by zone refining. The purity can be checked by gas chromatography. [Beilstein 1 H 429, 1 I 219, 1 II 466, 1 III 1815, 1 IV 1876.]


Incompatible with strong oxidizing agents. Cetyl alcohol is responsible for lowering the melting point of ibuprofen, which results in sticking tendencies during the process of film coating ibuprofen crystals.

Regulatory Status

Included in the FDA Inactive Ingredients Database (ophthalmic preparations, oral capsules and tablets, otic and rectal preparations, topical aerosols, creams, emulsions, ointments and solutions, and vaginal preparations). Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Nonmedicinal Ingredients.
