Harmful Effects of Triethylamine


Why we do NOT use Triethylamine in our products

Triethylamine is a colorless flammable liquid with a strong fishy ammonia-like odor. It is used in various industrial processes, such as in the production of pharmaceuticals, pesticides, and rubber chemicals. While it has its practical applications, it is essential to be aware of its potential harmful effects on both the body and the skin.


Acute Effects:

  • Acute exposure to triethylamine vapor can cause immediate and distressing effects on the body. One of the most notable consequences is eye irritation, which may manifest as corneal swelling and halo vision. Some individuals exposed to the vapor have reported experiencing "blue haze" or "smoky vision." Fortunately, these effects are typically reversible once exposure ceases.

  • Additionally, triethylamine can irritate the skin and mucous membranes upon direct contact.

  • Animal testing has shown that triethylamine has moderate to high acute toxicity when ingested orally and high acute toxicity when absorbed through the skin. Inhalation of triethylamine has also been found to be moderately toxic in animal tests conducted on rats, mice, and rabbits.

Chronic Effects :

  • Chronic exposure to triethylamine vapor in the workplace has been associated with the development of reversible corneal edema, a condition where the cornea becomes swollen due to fluid accumulation. This highlights the importance of implementing safety measures to prevent prolonged exposure in occupational settings.

Skin Effects:

  • Direct skin contact with triethylamine can lead to skin irritation and may cause redness, itching, or burning sensations. Due to its slightly soluble nature in water, it may penetrate the skin and exacerbate the irritation. It is essential to avoid skin contact with this chemical and to use appropriate protective equipment, such as gloves and safety clothing, when handling it.

Triethylamine is a chemical with potential harmful effects on both the body and the skin. Acute exposure can lead to eye irritation, corneal swelling, and other reversible vision-related issues. Chronic exposure, especially in occupational settings, may result in respiratory inflammation and other adverse health effects. Direct skin contact can cause skin irritation and discomfort.

Therefore, LEMYKA does not use triethylamine in its products in order to ensure the safety of our customers and especially those who use on sensitive skin, baby’s skin, or those who are pregnant.
