Pharmaceutical Tablet Film Coatings | PharmaCentral
Pharmaceutical Tablet Film Coatings October 20, 2025 A pharmaceutical film coating is a polymer-based membrane applied onto solid dosage forms, such as tablets, capsules and granules, in order to impart certain desired attributes that are otherwise absent in the uncoated product.
Natural-based plasticizers and biopolymer films: A review
Over the last half century, legislation and health safety issues have led to the development of a wide range of currently-available commercial plasticizers. They include some fatty acid esters, benzoates, tartrates and chlorinated hydrocarbons, esters of adipic, azelaic and sebacic acid.
Title: A Review on Plasticizers and Eco-Friendly
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
Thin-film drug delivery
Pullulan has been the most widely used film former (used in Listerine PocketPak, Benadryl, etc.) Plasticizers [ edit] Plasticizer is a vital ingredient of the OS formulation. It helps to improve the flexibility and reduces the brittleness of the strip.
Gelatin and Non-Gelatin Capsule Dosage Forms - PubMed
Capsule shells, available as hard or soft shells, are formulated from gelatin or a non-gelatin polymeric material such as hypromellose and starch, water, and with or without a nonvolatile plasticizer. The capsule shells may also be formulated to modify the release of their fill contents in a site-specific manner in the gastrointestinal tract.
- Which plasticizer is incorporated in cellulose acetate films?
- The common plasticizer incorporated in cellulose acetate films is glycerol . This plasticizer has been shown to improve the mechanical and thermal properties of cellulose acetate films.
- Which compounds are used in plasticizers for sunflower protein isolate films?
- The use of five compounds (GLY, EG, DEG, TEG and PG) as plasticizers for sunflower protein isolate films, producing soft, brown and smooth films, with good mechanical properties and a high level of impermeability to water vapor .
- Can cellulose acetate films be plasticized with glycerol and tehp?
- According to these results the cellulose acetate films without any plasticizer and the films plasticized with glycerol and TEHP showed a very low degradation rate after 60 days. While the degradation rate is significant for cellulose acetate films plasticized with rosemary essential oil.
- What are biodegradable plasticizers?
- Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
- Are cellulose acetate films biodegradable in soil?
- These results confirm that cellulose acetate films developed incorporating different types of plasticizers are biodegradable in soil, and that the biodegradability of the films increases with the incorporation of rosemary essential oil compared to the other plasticizers tested including glycerol and TEHP. Fig. 6.
- Which plasticizer is best for gelatin films?
- In terms of functional properties, GLY presented higher plasticizing effect and efficiency. Other plasticizers such as sucrose, oleic acid, citric acid, tartaric acid, malic acid, PEG, sorbitol, mannitol, EG, DEG, TEG, EA, diethanolamine (DEA) and TEA were also applied for gelatin films, modifying their mechanical and barrier properties.
