Description and Uses
Diethanolamine is an organic base which has been used as an emulsifying and dispersing agent.It can also be used as a basic buffer, with optimal pH about pH 9, if titrated with HCl or other acid. Other uses include: to "scrub" gases, as a chemical intermediate, as humectant or softening agent.
Diethanolamine similar to triethanolamine (T775580) is used as a surfactant. It also has the potential to be a corrosion inhibitor by means of chemisorption.
