Micellar electrokinetic chromatography (MEKC) was used to measure hydrophobicity of 18 aromatic compounds. The capacity factors, which are proportional to the micelle-water distribution coefficients, were closely correlated with the octanol-water partition coefficients. The addition of Brij 35 to the charged micelle was effective in improving the correlation because the surface charges of the micelle were shielded.

UI	MeSH Term	Description	Entries
D008823	Micelles	Particles consisting of aggregates of molecules held loosely together by secondary bonds. The surface of micelles are usually comprised of amphiphatic compounds that are oriented in a way that minimizes the energy of interaction between the micelle and its environment. Liquids that contain large numbers of suspended micelles are referred to as EMULSIONS.	Micelle
D011092	Polyethylene Glycols	Polymers of ETHYLENE OXIDE and water, and their ethers. They vary in consistency from liquid to solid depending on the molecular weight indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.

D002845	Chromatography	Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts.	Chromatographies
D004563	Electrochemistry	The study of chemical changes resulting from electrical action and electrical activity resulting from chemical changes.	Electrochemistries
D000077423	Polidocanol	An alkyl polyglycol ether of LAURYL ALCOHOL, chemically defined as an alcohol ethoxylate having an average alkyl chain of 12–14 carbon atoms, and an ethylene oxide chain of 9 ethylene oxide units. It is used as a detergent, and medically as a local anesthetic, and as a sclerosing agent for the treatment of ESOPHAGEAL AND GASTRIC VARICES and VARICOSE VEINS.
