Role of plasticizer in membrane coated extended release oral drug
Primary plasticizers can be used alone if they have suitable compatibility with the polymers and have ability to demonstrate required properties. On the other hand, primary plasticizers are also used along with secondary plasticizers to improve their efficiency. Ideality of the plasticizer changes with respect to the polymer.

Plasticizer - an overview | ScienceDirect Topics
A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of plasticizer needed to obtain a certain hardness or elongation is a measure of its efficiency.
Title: A Review on Plasticizers and Eco-Friendly Bioplasticizers
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887...
Plasticizers derived from cardanol: synthesis and plasticization
Two natural plasticizers derived from cardanol (CD), cardanol acetate (CA) and epoxidized cardanol acetate (ECA), were synthesized and characterized by 1H NMR and 13C NMR. The plasticizing effects of the obtained plasticizers on semi-rigid polyvinylchloride (PVC) formulations were also investigated. Two commercial phthalate ester plasticizers, dioctyl terephthalate (DOTP) and diisononyl
- What is the global demand for plasticizers in 2024?
- In the fourth edition of its Plasticizers market study, Germany's Ceresana forecasts that global demand for all plasticizers will increase to about 9.75 million tonnes in 2024, with typical volume growth rates for the different types of about 3–3.5%.
- What is the demand for plasticizers?
- Among the different types of plastics, demand for plasticizers is highest from polyvinyl chloride (PVC). In 2016, 2.14 million tonnes of plasticizers were used solely in films, followed closely by cables and profiles.
- What is the global demand for non-phthalate plasticizers?
- In volume terms, demand for non-phthalate plasticizers is forecast to grow at 3.2% per annum. The Asia Pacific region accounted for about 59% of global demand for plasticizers in 2016; due to above-average growth rates, demand in this region is expected to rise to about 6 million tonnes by the end of the forecast period.
- What is plasticized polyvinyl chloride (PVC)?
- Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing.
- How many plasticizers are there in the world?
- In 2016, 2.14 million tonnes of plasticizers were used solely in films, followed closely by cables and profiles. The study predicts that demand for plasticizers in cables and cable sheathing applications will see the highest increases until 2024.
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
