This doc discusses the HLB (hydrophilic lipophilic balance) method for classifying surfactants. It points out that HLB values suggest whether a surfactant is much more hydrophilic or lipophilic. Methods for estimating a surfactant's HLB price require assigning team numbers to diverse aspects of the molecule.
Derivatives of phenanthrene like papaverine are utilized as vasodilators to raise blood circulation. Phenanthrene and its derivatives have several medicinal uses like producing dyes, performing as antifungals, and currently being parts of steroids, sex hormones, bile acids, and cardiac glycosides.
