Toxicity Summary

Introduction to Toxicity

2-Methylaminoethanol is a viscous liquid utilized in various industries, including textiles and pharmaceuticals. Although it serves essential roles in manufacturing, 2-Methylaminoethanol poses significant health risks upon exposure. Prolonged exposure to 2-Methylaminoethanol can lead to serious health effects such as hematuria, abnormal liver function tests, and dermatological manifestations such as multiple skin warts. Animal studies have demonstrated that 2-Methylaminoethanol can irritate the skin, eyes, and mucous membranes, indicating its corrosive potential. However, experiments conducted on rats revealed that at a concentration of 150 parts per million, 2-Methylaminoethanol did not exhibit maternal or embryotoxic effects. Additionally, it has shown no mutagenic activity in specific bacterial strains. Understanding the toxicity of 2-Methylaminoethanol is crucial for mitigating risks associated with its use in various applications. ²

Symptoms and Adverse Effects

Exposure to 2-Methylaminoethanol can occur via inhalation, skin contact, or ingestion, each route leading to distinct symptoms. Inhalation may result in sore throat, cough, burning sensations, and even labored breathing. Skin exposure to 2-Methylaminoethanol can cause pain, redness, and severe burns. Eye contact with 2-Methylaminoethanol is particularly alarming, often leading to deep burns and potentially permanent loss of vision. Ingesting 2-Methylaminoethanol could provoke abdominal pain and severe reactions like shock or collapse. These adverse effects are compounded by its classification as a dermatotoxin, capable of causing severe skin burns. Given its toxicity profile, proper safety measures must be adopted when working with or near 2-Methylaminoethanol to protect against its harmful effects. ²
