Effects of Fulvic Acid on Skin
A composition which has bactericidal or bacteriostatic properties comprises coal-derived fulvic acid or a salt or a derivative thereof as active ingredient in a suitable carrier. The carrier is preferably water. ____________________________________________________________________________ Bacteriostatic and bacteriocidal method using fulvic acid derivatives United States Patent 5,204,368 Invento...
متن کاملEu(III)-Fulvic Acid Complexation: Evidence of Fulvic Acid Concentration Dependent Interactions by Time-Resolved Luminescence Spectroscopy.
Europium speciation is investigated by time-resolved luminescence spectroscopy (TRLS) in the presence of Suwannee River fulvic acid (SRFA). From complexation isotherms built at different total Eu(III) concentrations, pH values, ionic strength, and SRFA concentrations, it appears that two luminescence behaviors of Eu(III) are occurring. The first part, at the lowest CSRFA values, is showing the ...
متن کاملSolubility and Dissolution Enhancement of Silymarin with Fulvic Acid Carrier
Objective: Solubility is a key parameter as it is one of the main causes for poor bioavailability. The objective was to improve the solubility and dissolution profile of poorly-soluble silymarin with a water-soluble carrier fulvic acid. Materials and methods: Phase solubility studies were carried out for the determination of stoichiometric ratio between silymarin and fulvic acid by Higuchi and ...
متن کاملAdsorption characterizations of fulvic acid fractions onto kaolinite.
Fulvic acids extracted from a typical rice-production region near Taihu Lake of China were fractionated into three fractions including F4.8, F7.0 and F11.0 (eluted by pH 4.8 buffer, pH 7.0 buffer and pH 11.0 buffer, respectively). Sorption of fulvic acid (FA) fractions onto kaolinite was studied by batch adsorption experiments, and characterizations of kaolinite before and after adsorption were...
متن کاملIsolation and Characterization of Chinese Standard Fulvic Acid Sub-fractions Separated from Forest Soil by Stepwise Elution with Pyrophosphate Buffer
XAD-8 adsorption technique coupled with stepwise elution using pyrophosphate buffers with initial pH values of 3, 5, 7, 9, and 13 was developed to isolate Chinese standard fulvic acid (FA) and then separated the FA into five sub-fractions: FApH3, FApH5, FApH7, FApH9 and FApH13, respectively. Mass percentages of FApH3-FApH13 decreased from 42% to 2.5%, and the recovery ratios ranged from 99.0% t...
