Gelucire® is Gattefossé’s brand of semi-solid excipients originally designed for hard gelatin capsule molding. The name results from the fusion between « gélule » meaning capsule and « cire » meaning wax. Following the name, there is a set of two figures: the first (eg 44) indicates the melting point in Celsius degree, the second (eg 14) indicates the theoretical HLB (Hydrophilic Lipophilic balance). The family is composed of four products with their own characteristics, specificities...

Poly ethylene glycol (PEG) ester surfactants are synthesized by reacting polyethylene glycol with fatty acid. The polyethylene glycol comprises the hydrophilic part of the surfactant and the fatty acid is the lipophilic part. By varying the molecular weight of the PEG and the fatty acid, surfactants covering wide range of hydrophilic lipophilic balance (HLB) values can be produced. Gelucire is the family of vehicle derived from mixtures of mono, di and triglycerides with PEG esters of fatty...

Cell-free permeation systems are gaining interest in drug discovery and development as tools to obtain a reliable prediction of passive intestinal absorption without the disadvantages associated with cell- or tissue-based permeability profiling. Depending on the composition of the barrier, cell-free permeation systems are classified into two classes including (i) biomimetic barriers which are constructed from (phospho)lipids and (ii) non-biomimetic barriers containing dialysis membranes. This...

he aim of the study was to investigate the effect of novel polymer/lipid formulations on the dissolution rates of the water insoluble indomethacin (INM), co-processed by hot melt extrusion (HME). Formulations consisted of the hydrophilic hydroxypropyl methyl cellulose polymer (HPMCAS) and stearoyl macrogol-32 glycerides—Gelucire 50/13 (GLC) were processed with a twin screw extruder to produce solid dispersions.
