A series of supramolecular diamide organogels containing a reactive compound for the remediation of organophosphorus (OP) species, in particular OP chemical warfare agents (CWAs), has been prepared in DMSO. The organogels have been found to absorb, encapsulate and decontaminate various OP CWA simulants in situ. At high simulant concentrations the gels also undergo a gel–sol transition releasing...

12-Hydroxystearic acid (12-HSA) xerogels derived from 12-HSA-acetronitrile organogels are highly effective sorbent materials capable of adsorbing apolar, spilled materials in aqueous environments. 12-HSA xerogels made from 12-HSA-acetronitrile organogels are more effective than 12-HSA xerogels made from 12-HSA-pentane organogels because of the highly branched fibrillar networks established in a...

This article provides a brief and basic discussion of Pluronic lecithin organogel to include its history, its components, its mechanism of action, the range of active pharmacological agents that can and cannot be incorporated into a Pluronic lecithin organogel, as well as important information for those pharmacists who compound Pluronic lecithin organogel.

Organogel is a viscoelastic carrier system, can be regarded as a semi-solid preparation which has an immobilized external organic (apolar) phase. Organogels have evolved as one of the potential carrier system for topical delivery. When compared to other lipid based carrier systems, these prove to be better in terms of efficacy, feasibility and shelf life. Organogelator such as n-alkanes, fatty ...

Rice bran wax (RBX) obtained during rice bran oil purification can form organogels in edible oils. The kinetics of crystallization and the viscous properties of RBX organogels were studied using differential scanning calorimetry (DSC), viscosity changes with varying temperature, hardness measurements by penetrometry, and synchrotron radiation X-ray diffraction (SR-XRD). The organogels were prep...

Solvent-gelator interactions play a key role in mediating organogel formation and ultimately determine the physico-chemical properties of the organogels and xerogels. The ethanol organogels of 1,4-bis[(3,4,5-trihexyloxy phenyl)hydrazide]phenylene (TC6) were investigated in situ by FT-IR, Raman and fluorescence spectra, and XRD, and it was confirmed that the intermolecular interaction and aggreg...

Supramolecular gels comprised of low-molecular-weight gelators are generally regarded as mechanically weak and unable to support formation of free-standing structures, hence, their practical use with applied loads has been limited. Here, we reveal a technique for in situ generation of high tensile strength supramolecular hydrogels derived from low-molecular-weight gelators. By controlling the c...

Probiotic formulations containing lecithin phospholipids have been shown to extend their viability. However, the protective effect of and properties mixtures probiotic cells in aqueous media not fully documented. The aim this study was investigate interactions between Bifidobacterium animalis ssp. lactis (Bifido) probiotics lecithin. lecithin-Bifido were dependent on concentration. FTIR Raman s...

Organogels (hydrophobic polymer gels) are soft materials based on polymeric networks swollen in organic solvents. They hydrophobic and possess a high content of solvent low surface adhesion, rendering them interesting applications such as encapsulants, drug delivery, actuators, slippery surfaces (self-cleaning, anti-waxing, anti-bacterial), or for oil-water separation. To design functional orga...

Low volatility solvent/non-solvent mixtures were utilized to engineer the structure of poly(3-alkylthiophene) (P3AT) organogels. The ratio of solvent to poor-solvent was manipulated to systematically control the kinetics of self-assembly. Specific solvent mixtures were utilized to produce similar gelation kinetics with polymers of differing alkyl chain length. Simultaneous small angle neutron s...
