Preparation of ethyl cellulose/methyl cellulose blends by supercritical antisolvent precipitation.

The supercritical antisolvent (SAS) technique was used to prepare ethyl cellulose/methyl cellulose blends, two biocompatible polymers commonly used as drug carriers in controlled delivery systems. Ethyl cellulose is widely used as a drug carrier. The drug release of the delivery devices can be controlled to some extent by addition of a water-soluble or water swellable polymer, such as methyl ce...

Supercritical Antisolvent (sas) Co-precipitation of Ethyl Cellulose and Natural Extracts in Sc-co2

The objective of this work has been the co-precipitation of the coating material Ethyl Cellulose (EC) and two natural extracts (IDOKI SCF Technologies), R1 and P1, using the Supercritical Antisolvent (SAS) precipitation technique with supercritical carbon dioxide (SC-CO2), in order to obtain active microparticles. EC is a hydrophobic material widely used for controlled delivery systems, sustain...

Supercritical antisolvent precipitation of PHBV microparticles.

The micronization of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) from organic solutions using supercritical antisolvent (SAS) technique has been successfully achieved. SAS experiments were carried out at different operational conditions and microspheres with mean diameters ranging from 3 to 9 microm were obtained. The effect of CO(2) and liquid flow, temperature and pressure on particle...

Purification and Simultaneous Micronization of Polymers by Supercritical Antisolvent Precipitation

One of the most important environmental concerns for the polymer industry is to produce new products with near-zero residual monomer content. A new process based on supercritical CO2 has been successfully tested for the extraction of the residual monomer and the simultaneous micronization of the polymer. The process has been tested on a pilot-scale plant. The reduction of methyl methacrylate (M...

Micronisation of Ethyl Cellulose by Supercritical Anti-solvent Process

Supercritical Anti-Solvent (SAS) process is considered as a clean technology suitable for particle design, micron or nanometer sized. It is generally used to micronize compounds of interest in mild operating conditions of temperature and nearly without any residual solvent traces in the end-product. By varying the process parameters, the properties of the produced powders can be adjusted with a...
