DMAE is a skin care ingredient said to improve skin tone and reduce the appearance of wrinkles. It is also said to improve alertness and cognitive function.

DMAE is a controversial substance. Some believe it is effective in treating a variety of ailments, while others believe it is not effective and may even be harmful. More research is needed to determine the safety and effectiveness of DMAE.

DMAE is also used in the manufacture of other chemicals such as the nitrogen mustard 2-dimethylaminoethyl chloride. Acrylates are used as flocculants. Related compounds are used in gas cleaning, such as the removal of hydrogen sulfide from sour gas streams.
