Introduction of fuel hydrocarbons and inorganic compounds (heavy metals) into the soil, resulting in a change of the soil quality, which is likely to affect use of the soil or endangering public health and ground water. This study aimed to determine a series of parameters to remediation of TPH and heavy metals contaminated soil by non-ionic surfactants- chelating agents washing process. In this...

Proniosomal formulations with non-ionic surfactant were studied. The effect of hydrophilicity and hydrophobicity of one or two surfactants on drug solubility, proniosome surface structure and stability and skin permeation of haloperidol from different formulations were investigated. Haloperidol (HP) was entrapped in proniosomes with very high efficiency for all formulations. Stability studies p...

A colorimetric strategy based on conjugated polyelectrolyte aggregates has been applied to determine and distinguish anionic, cationic and non-ionic surfactants.

A nonionic surfactant, n-dodecyl glyceryl itaconate (DGI), self-assembles into bilayer membranes in water having a spacing distance of sub-micrometer in the presence of small amounts of ionic surfactants, and shows beautiful iridescent color. Ionic surfactants have strong effects on this iridescent system. We have interestingly found that the iridescent color changes with time after mixing DGI ...
