4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Surface-Active Agents

Agents that modify interfacial tension of water; usually substances that have one lipophilic and one hydrophilic group in the molecule; includes soaps, detergents, emulsifiers, dispersing and wetting agents, and several groups of antiseptics. (See all compounds classified as Surface-Active Agents.)


Detergents

Purifying or cleansing agents, usually salts of long-chain aliphatic bases or acids, that exert cleansing (oil-dissolving) and antimicrobial effects through a surface action that depends on possessing both hydrophilic and hydrophobic properties. (See all compounds classified as Detergents.)


4.2 Absorption, Distribution and Excretion

(1-Dodecyl-14C)lauramine oxide (10 mg with 100 uCi of 14C) was applied to the skin of two humans to study cutaneous absorption and metabolism of lauramine oxide. Ninety-two percent of the applied radioactivity was recovered from the skin of the test subjects 8 hr after dosing, and 0.1 and 0.23% of the radioactivity was recovered from the excretion products of the test subjects. The stratum corneum contained <0.2% of the applied dose.

Oral administration of a solution containing 50 mg (1-dodecyl-14C)lauramine oxide (100 uCi of 14C) to two humans resulted in excretion patterns of radioactivity similar to that of the other species studied. Fifty percent and 37% of the radioactivity was found in the urine within 24 hr of dosing, and expired 14C02 contained between 18 and 22% of the radioactivity administered.

Cosmetic Ingredient Review; Final Report on the Safety Assessment of Lauramine Oxide and Stearamine Oxide; Journal of American College of Toxicology 13 (3): 231-45 (1994)


Four Sprague-Dawley rats were given intraperitoneal injections of 22 mg (methyl-14C)lauramine oxide kg (specific activity 1.3 mCi/g). Sixty-seven percent of the total radioactivity was eliminated in the urine, 8% was expired as I4CO2, and 6% was eliminated in the feces within 24 hr. The distribution of radioactivity was essentially the same as that seen in rats given oral doses of lauramine oxide. The conclusion was that "... microbial metabolism by gastrointestinal flora does not play a major role in the absorption and excretion of [lauramine oxide] in rats."

Aqueous (methyl-14C)lauramine oxide (10 mg containing 1.3 mCi/g) was applied to the skin of four Sprague-Dawley rats to test metabolism and absorption of the compound. Over 72 hr, 14.2% of the total radioactivity was found in the urine, 2.5% in the CO2, and 1.8% in the feces. Radioactivity was detected in the liver, kidneys, testes, blood, and expired CO2.

4.3 Metabolism/Metabolites

Metabolic profiles for different species (rat, human, mouse, rabbit) did not have any significant differences in metabolites, but the degree of absorption, especially in cutaneous applications, varied from species to species.

Cosmetic Ingredient Review; Final Report on the Safety Assessment of Lauramine Oxide and Stearamine Oxide; Journal of American College of Toxicology 13 (3): 231-45 (1994)


Characterization of metabolites of lauramine oxide resulted in the positive identification of only one metabolite, N-dimethyl-4-aminobutyric acid N-oxide. Several pathways exist for metabolism of lauramine oxide: omega,beta-oxidation of alkyl chains (the most common pathway for surfactant metabolism), hydroxylation of alkyl chains, and reduction of the amine oxide group.

Cosmetic Ingredient Review; Final Report on the Safety Assessment of Lauramine Oxide and Stearamine Oxide; Journal of American College of Toxicology 13 (3): 231-45 (1994)


Urinary metabolites in rats, rabbits and humans suggested metabolism via omega, beta-oxidation of the aliphatic chain, amine oxide reduction and aliphatic, mid-chain hydroxylation. N,N-dimethyl-4-aminobutyric acid and its N-oxide accounted for 28, 28 and 23% in man, rats and rabbits, respectively.
