Product Application of Diisopropanolamine CAS#110-97-4
Bis(2‑hydroxypropyl)amine (Diisopropanolamine) is used to investigate impacts on choline absorption and phospholipid production in Chinese hamster ovary (CHO) cells. As a multifunctional chemical, it acts widely as an emulsifier, stabilizer, surfactant, and synthetic intermediate. It regulates pH, buffers solutions, and supplies alkalinity. Main uses include personal care formulations, metalworking fluids, and natural gas purification. It also appears in coatings, paint removers, paper, photographic chemicals, plastics, polyurethanes, and textiles, and is often used to neutralize fatty acids and sulfonic acid surfactants.
