While longer-chained parabens possess greater antimicrobial properties, they also exhibit decreased water solubility, thus making the shorter-chained methyl and propylparabens better suited for their application in foods. Parabens are effective against the proliferation of yeasts and molds at much lower ...

2.8 Water Solubility Soluble in Chloroform, Ethyl Acetate. 2.9 StorageTemp Sealed in dry,2-8°C3. Use and Manufacturing3.1 Description Isopropylparaben, with the chemical formula C12H14O3, has the CAS number 4191-73-5. It is a chemical compound that belongs to the class of parabens. Iso...
Thermodynamic analysis of the individual solubility of propylparaben and -cyclodextrin was carried out in water at different temperatures. In aqueous -cyclodextrin solutions, however, the solubility of propylparaben is enhanced due to the formation of both SL (G°11 = -26.4 kJ/mol) and S2L (G...

In fact, at the second step, cyclohexylamine has the role of both dispersive solvent and phase separation agent which controls the solubility of 1-butyl-3-methylimidazolium chloride in the aqueous phase and a, simultaneously. The separated extraction phase after centrifugation was injected to HPLC-...
HP-beta-CyD significantly increased the solubility of methyl paraben in water, where the apparent 1:1 stability constant of the soluble complex was determined to be 2150 M-1. The in-vitro cutaneous permeability of methyl paraben through an isolated skin of hairless mouse was suppressed by HP-...
