2-Dimethylaminoethanol Chemical Properties,Uses,Production
Description
Dimethylaminoethanol is a colorless liquidwith a pungent odor. Odor threshold: 0.25 ppm. Molecularweight 5 89.16; Boiling point =133℃; Freezing/Meltingpoint=259℃; Flash point =41℃ (oc); Autoignitiontemperature 5=295℃. Explosive limits: LEL 5=1.6%;UEL 5=11.9%. Hazard Identification (based on NFPA-704M Rating System): Health 2, Flammability 2, Reactivity 0.Soluble in water.
Chemical Properties
colorless or slightly yellow liquid with ammonia odor. It is miscible with water, ethanol, benzene, ether and acetone.
Uses
dimethyl MEA (DMAE) is also known as dimethylaminoethanol. Studies indicate skin-firming properties, and an ability to reduce the appearance of fine lines and wrinkles as well as dark circles under the eyes. It is considered anti-aging, and antiinflammatory, and has exhibited free-radical scavenging activity.
