Exploiting Polymeric Films as a Multipurpose Drug Delivery
The plasticizers improve the mechanical properties of the films. With them, the elongation and the tensile strength are enhanced. The most common plasticizers are glycerols, triethyl and tributyl citrates, and diethyl phthalate [ 26 ]. The surfactants can be present or not in the films. They may disperse, wet, and solubilize the film.

Natural-based plasticizers and biopolymer films: A review
Natural plasticizers used in biodegradable films from biomass products (polysaccharide-, protein-, and lipid-based films) or other films obtained by extraction of micro-organisms. Refs. Soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) 6.1.

They are polymeric plasticizers that facilitate the formulation of compounds for PVC having good resistance to extraction by oils, greases, liquid simulating the contact with food (especially olive oil and other vegetable oils ); they are also characterized by low volatility, minimal tendency to migration in contact with other thermoplastic material and have, at the same time, an excellent
GLYCEROL DERIVATIVES AS A MODERN PLASTICIZERS FOR STARCH FILMS
low price, abundant, biodegradable, and edible. Films prepared from starches are isotropic, odourless, tasteless, colourless, non-toxic and biodegradable. Finally, they are nutritious and safe, so they are used in the marketing of food. Unfortunately, the starch films present poor tensile properties and sensitivity to moisture content.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- 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.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- What are the benefits of topical polymeric films & transdermal patches?
- Due to their benefits such as physical barrier formation, ease of application, and reduced dosing frequency, topical polymeric films and transdermal patches are often associated with improved patient compliance.
- What types of plasticizers are used in hydrophilic polymers?
- In addition to water, the most commonly used plasticizers are polyols, mono-, di- and oligosaccharides. Polyols have been found to be particularly effective for use in plasticized hydrophilic polymers .
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
