Product Description of LDAO CAS# 1643-20-5
LDAO is a colorless to light yellow transparent liquid with a relative density of 0.98 at 20°C. It is easily soluble in water and polar organic solvents, slightly soluble in non-polar solvents, and exhibits non-ionic or cationic behavior in aqueous solutions. At pH values below 7, it becomes cationic. As an amine oxide, LDAO serves as an excellent detergent and generates stable, rich foam. Its melting point ranges from 132 to 133°C, ensuring reliable performance in various formulations.
