A nonionic surfactant (alkyl phenoxy polyethoxy ethanol) solubilizes antibiotic preparations containing up to 1 per cent lecithin. Toxicity studies showed that the surfactant at a concentration of 0.1 per cent (v/v) in 0.1 per cent peptone solution (w/v) permits recovery from a low inoculum of veget

The objective of this study was to model the critical micelle concentration (cmc) of nonionic surfactants in nonaqueous systems using the UNIFAC group contribution method. For the prediction of the cmc the phase separation approach was used, where the micellar phase is approximated as a second liqui
## Abstract Although nonionic compounds can be separated by micellar electrokinetic chromatography (MEKC), application of this technique is restricted by a somewhat limited elution range. Incorporation of organic solvents in the background electrolyte (BGE) greatly extends the scope of MEKC and pro
