- Background
Trolamine, which is also referred to as triethanolamine (TEA), is a tertiary amine and a triol. It is a bifunctional compound that exhibits both properties of alcohols and amines. Trolamine contains small amounts of diethanolamine and ethanolamine and may also act as an antioxidant against the auto-oxidation of animal and vegetable fats 1. It is commonly used as a pH adjuster and surfactant in industrial and cosmetic products such as skin and hair conditioning products.

Pharmacology
- Indication
Trolamine is used as an alkalizing agent, surfactant, and counter-ion in cosmetic and pharmaceutical formulations 1. It is not considered to be an active pharmacological ingredient and so has no official indication.

Acts as a surfactant or alkalizing agent to aid in emulsification and solubilizing of compounds or in raising the pH of a solution 1
- Mechanism of action
As an amine, trolamine is capable of accepting a hydrogen to form hydroxide and a conjugate acid. This raises the pH of the solution. As a surfactant, it can lower the interfacial tension in a mixture or solution to prevent separation of emulsions or precipitation of a compound out of solution.
- Absorption
Dermal absorption of trolamine increases with the dose 1. This has been found to range from 19-28% in rats with doses of 68-276 mg/kg in 190 μL of acetone without occlusion and from 60-80% in mice with doses of 79-1120 mg/kg in the same volume of acetone.

- Route of elimination
When orally administered to rats, the 53% of the trolamine dose was found to be excreted in the urine and 20% in the feces 1. 98% was excreted in the urine with intravenous administration.

Trolamine produced mild erythema and edema in rabbits with dermally administered doses of 2 g/kg under occlusion 1. The oral LD50 was found to be 8 g/kg in guinea pigs and 4.19-11.26 g/kg in rats. Repeated oral administration in rats and guinea pigs produced hepatic and renal damage with deaths occurring in rats at doses >0.3 g/kg/day. When inhaled trolamine produced edema and inflammation in rats at doses over 100 mg/m³ after 5 days and at doses over 4.7 mg/m³ after 90 days. There is some evidence of carcinogenicity at high dermal doses (1000 mg/kg/day) in mice. Trolamine is not classified as a carcinogen in humans.
