Recent Advances in Plasticizers 46 2. Pharmaceutically used plasticizers The primary role of all plasticizers as low molecular weight non-volatile additives is to improve the flexibility and processability of polymers by lowering the second order transition temperature (glass transition temperature, Tg) (Rosen, 1993). The extent of Tg

- Are plasticizers suitable for pharmaceutical applications?
- The extensive use of polymers in medical and pharmaceutical applications including particularly packaging, medical devices, drug carriers and coatings has caused a substantial demand for the proper plasticizers. Although there are many plasticizers used in the chemical industry, only a few of them have been approved for pharmaceutical applications.
- Are natural-based plasticizers suitable for pharmaceutical and medical applications?
- The natural-based plasticizers characterized by low toxicity and low migration are required nowadays not only for pharmaceutical and medical applications. In this respect, most of traditional plasticizers are not applicable in this area.
- What is a plasticizer in chemistry?
- ABSTRACT A plasticizer is a substance the addition of which to another material makes that material softer and more flexible. Most often plasticizers are materials which, when added to a polymer, cause an increase in the flexibility and workability, brought about by a decrease in the glass-transition temperature of the polymer.
- What are the different types of plasticizers used in polymers?
- Oily, waxy,or fatty substances were applied as plasticizers. Other i nvention polymer matrix. poly- DL -lactide- co-glycolide (PLGA) were produced. plasticizer, PEG, was added to the polymers. It was degradation-controlled phase. The plasticizer accelerated polymer. The plasticizer dep ressed the burst effect for controlled phase.
- Which polymers are plasticized with hygroscopic plasticizing effect?
- The polymers plasticized with hygroscopic plasticizing effect. The thermoplastic starch is a material interesting for the use in pharmacy. It is p roduced by native granules and 2 0 % to 50 % glycerol. T his implantation. In the temperatures of 150 to 180 °C the produced. Glycerol and xylitol are important plasticizers
- Why do polymers use plasticizers?
- Plasticizers can be added to polymers to make them more flexible. Plasticizers are small lubricating behaviour, and adhesive property of polymeric films. drug release performance. WHAT IS A PLASTICIZER?
- to increase its flexibility. The plasticizer gets between makes the material more flexible. T he polymer will where flexibility is required.
