DOW Diethanolamine (DEA) offers a broad spectrum of application opportunities, primarilyin detergents, personal care products and textile finishing. Other applications include useas intermediates in agricultural and photographic chemicals, and as catalysts that promotestability during the reaction process in the manufacture of flexible and rigid urethane foams.Because DEA combines the properties of amines and alcohols, DEA exhibits the uniquecapability of undergoing reactions common to both groups. As an amine, DEA is mildlyalkaline and react with acids to form salts or soaps. As an alcohol, DEA is hygroscopic andcan be esterfied.DOW Diethanolamine is available as DEA & DEA LFG DEA is a commercial grade of diethanolamine (CAS number: 111-42-2).Â¢ DEA Low Freezing Grade (LFG) is a variation of DEA commercial grade for easierhandling in colder ambient temperatures (freezing point: -2ÂºC/28.4ÂºF). It is an 85%solution of DEA with 15% water.
Detergents DEA imparts a reserve alkalinity to the laundry bath, which is essential to efficient cleaning.DEA is an effective oil and anti-redeposition agent.Personal Care DEA is reacted with fats, oils or derived fatty acids to form fatty acid amides to form foam stabilizers, emulsifiers and viscosity builders in products such as shampoos andcosmetics.Textile Finishing DEA is used as reaction intermediates for the preparation of durable press fabricfinishes and softeners. When reacted to form amine soaps, useful as scouring agents for wool and silkbecause of its low alkalinity Because it is hygroscopic, DEA is used in the preparation of vat printing pastes. DEA is also useful in making acetate rayon dyes.
