in this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. the effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

UNLABELLED Since the existence of pHp was demonstrated, it has been shown that this molecule and its receptor CD163 are regulated by different stimuli. Furthermore, a comparably fast secretion of pHp was described as well as the immuno-stimulatory effects. The intention of this study was to elucidate the role of pHp in the human lungs further. Here we show, by means of confocal microscopy and i...

The aim of current research is to develop flurbiprofen microemulsion gel for transdermal delivery. To prepare a oil, surfactant and co-surfactant selection one the important criteria. Selected different ratios oil mixture using ternary phase diagram. Based on results physicochemical properties, we have optimized formulation. formulation incorporated into carbopol P 934 base. In vitro diffusion ...

A new type of scrolled structure of Co(3)O(4)/reduced graphene oxide (r-GO) is facilely prepared through a two-step surfactant-assisted method. This assembly enables almost every single Co(3)O(4) scroll to connect with the r-GO platelets, thus leading to remarkable electrochemical performances in terms of high specific capacitance and good rate capability.

BACKGROUND Lagerstroemia speciosa (SEL) leaves are a popular folk medicine for diabetes treatment due to presence of corosolic acid. It has low water solubility resulting poor absorption after oral administration. Self micro-emulsified drug delivery system is the way by which we can improve the oral absorption of drug. OBJECTIVE The objective of this study was to develop the self micro-emulsi...

Article history: Received on: 09/10/2014 Revised on: 27/10/2014 Accepted on: 18/11/2014 Available online: 29/12/2014 The objective of present study was to formulate hydrogel thickened Lornoxicam transdermal formulation. Eutectic mixture of camphor and menthol was chosen as oily phase (maximum 10%), solvent for Lornoxicam and powerful penetration enhancer. Tween 80, ethanol and Carbopol 934p, HP...

HYPOTHESIS Previous efforts to formulate smart foams composed of mixtures of PNIPAAm, a thermoresponsive uncharged polymer, and surfactants have failed because the surfactant displaces the PNIPAAm from the liquid-air interface, removing the thermal responsiveness. We hypothesized that thermoresponsive foams could be formulated with such a mixture if a charged surfactant were used in order to an...

In this report, results from the project, proposed in the original research plan are presented. 10 surfactant systems effective as drag reducing agents (DRA’s) in efficient district cooling, including four commercial cationic surfactants, one commercial and three novel synthesized zwitterionic surfactants, one commercial nonionic surfactant and one zwitterionic(synthesized)/anionic surfactant m...

Nanoparticles of nickel substituted cobalt ferrite (Nix Co1-xFe2 O4 : 0£ X£ 1) have been synthesized by co-precipitation method. Triton x-100 and oleic acid as surfactants were used. Particles size as estimated by the full width half maximum (FWHM) of the strongest X-ray diffraction (XRD) peak were found 17 and 21nm. Their morphology structure have been determined by scanning electron microscop...

PURPOSE The aim of the present research was to formulate a transparent microemolsion as a topical delivery system for tretinoin for the treatment of acne. METHODS Microemulsion formulations prepared by mixing appropriate amount of surfactant including Tween 80 and Labrasol, co-surfactant such as propylene glycol (PG) and oil phase including isopropyl myristate - transcutol P (10:1 ratio). The...
