In organic chemistry, alkanolamines (amino alcohols) are organic compounds that contain both hydroxyl (−OH) and amino (−NH2, −NHR, and −NR2) functional groups on an alkane backbone. Alkanolamine's bifunctionality and physicochemical characteristics lead to its use in many applications, such as textiles, cosmetics, agricultural chemical intermediates, drugs, and metal working fluids. Many aminoalcohols derivatives also have chemotherapeutic properties.
Alkanolamines usually have high-solubility in water due to the hydrogen bonding ability of both the hydroxyl group and the amino group. Alkanoamines have also shown a broad toxicity for a variety of organisms, including parasites, insect larvae and eggs, and microbes. Studies have also shown that the antimicrobial effect of alkanolamines increases in higher pH's. Most alkanolamines are colorless.
