Lauryldimethylamine oxide intermolecular interactions), DDAO is a strongly hydrophilic surfactant: it forms normal micelles and normal liquid crystalline phases. High hydrophilicity of this surfactant can be explained by the fact that it forms very strong hydrogen bonds with water: the energy of DDAO – water hydrogen bond is about 50 kJ/mol. Lauryldimethylamine oxide Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide based nonionic surfactant, with a C (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. Like other amine oxide based surfactants it is antimicrobial, being effective against common bacteria such as
U Should've Known Better producers, which included Dallas Austin, production team Soulshock & Karlin, Bryan Michael Cox, and Rodney Jerkins and his Darkchild crew. Though she "had never thought about writing much" by then, her producers encouraged the singer to intensify her work on the "All Eyez on Me" album and to write and contribute own lyrics and ideas to the songs, one of which was the ballad "U Should've Known Better." Monica penned the song along with Harold Lilly and longtime contributor Jermaine Dupri, while production on the track was helmed by Dupri and Bryan Michael Cox. "U Should've Known Better" was mixed
