4 Drug and Medication Information
4.1 Therapeutic Uses

A synthetic surfactant (Exosurf), and its non-surface-active components tyloxapol and cetyl alcohol, can function as antioxidants, and their in vivo instillation is associated with decreased hyperoxic injury in rats.

Bingham, E.; Cohrssen, B.; Powell, C.H.; Patty's Toxicology Volumes 1-9 5th ed. John Wiley & Sons. New York, N.Y. (2001)., p. 3:669


4.2 Minimum/Potential Fatal Human Dose

1(?). 1= Practically nontoxic: Probable oral lethal dose (human) above 15 g/kg; more than 1 quart (2.2 lb) for 70 kg person (150 lb).

Gosselin, R.E., R.P. Smith, H.C. Hodge. Clinical Toxicology of Commercial Products. 5th ed. Baltimore: Williams and Wilkins, 1984., p. II-174


4.3 Drug Indication

No therapeutic indications in medicinal products. Indicated to be used as an indirect additive in food contact substances, or an ingredient in commercial or cosmetic products.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Cetyl alcohol exhibits skin protect properties against skin irritations caused by bites, rashes and stings. The inhibitory action of cetyl alcohol against the growth of _Mycoplasma gallisepticum_ and _Mycopiasma pneumoniae_ has been reported.


5.2 Absorption, Distribution and Excretion

Absorption

Following ingestion at a dose level of 2.0 g/kg in rats, cetyl alcohol was partly absorbed. Administration of 0.2 mg cetyl alcohol in rat by stomach tube indicated good absorption as 63-96 % of radiolabeled cetyl alcohol was detected in the lymph. About 15% of total cetyl alcohol was unchanged during its passage through the mucosal cells of the small intestine but mostly underwent oxidation to palmitic acid. The extent of absorption was reported to be 26% in poultry.


Route of Elimination

Following ingestion at a dose level of 2.0 g/kg in rats, about 20% of the dose was recovered as unchanged molecule in the feces. This may be due to the interconvertibility of fatty acids and alcohols, resulting in the conversion of palmitic acid to cetyl alcohol during its passage through the intestinal mucosal cells into the intestinal lumen. In rats, cetyl Alcohol was also excreted in the urine as conjugated glucuronic acid and as expired carbon dioxide.


Following ingestion at a dose level of 2.0 g/kg bw /in rats/, 1-hexadecanone is partly absorbed and metabolized, about 20% of the dose being recovered unchanged in the feces.

Sheftel, V.O.; Indirect Food Additives and Polymers. Migration and Toxicology. Lewis Publishers, Boca Raton, FL. 2000., p. 486


5.3 Metabolism/Metabolites

Following ingestion at a dose level of 2.0 g/kg in rats, cetyl alcohol was partly metabolized to palmitic acid. After administration of 0.2 mg cetyl alcohol in rat by stomach tube, cetyl alcohol was mostly oxidized to palmitic acid and incorporated into triglycerides and phospholipids during its passage through the mucosal cells of the small intestine.


Cetyl alcohol is oxidized in rats to the corresponding fatty acid, palmitic acid.

Bingham, E.; Cohrssen, B.; Powell, C.H.; Patty's Toxicology Volumes 1-9 5th ed. John Wiley & Sons. New York, N.Y. (2001)., p. 6:494


The primary aliphatic alcohols undergo two general reactions in vivo, namely oxidation to carboxylic acids and direct conjugation with glucuronic acid. The first reaction proceeds with the intermediate formation of an aldehyde, and the carboxylic acid from this may be either oxidized completely to carbon dioxide or excreted as such or combined with glucuronic acid as an ester glucuronide. The extent to which as alcohol undergoes the second reaction, i.e. direct conjugation to an ether glucuronide, appears to depend upon the speed of the first reaction, for alcohols which are rapidly oxidized from very little ether glucuronide unless given in high doses.

5.4 Mechanism of Action

Cetyl alcohol has hydrating properties that makes it a suitable emulsifier and stabilizer in pharmaceutical formulations. It is also present in washable ointment base due to its dispersant abilities and stabilizing properties. Potential antimicrobial activity of cetyl alcohol may be due to a change in cell membrane permeability that either blocks absorption of essential nutrients and induction of outward diffusion vital cellular components. This proposed mechanism of action is thought to be similar for other long-chain aliphatic alcohols with same antimicrobial activity, such as myristyl alcohol and behenyl alcohol.
