Pharmaceutical Tablet Film Coatings | PharmaCentral
Polymers used in conventional film coatings This category includes: cellulose ether derivatives, e.g., hypromellose (also called hydroxypropyl methylcellulose), methylcellulose, hydroxypropylcellulose and sodium carboxy methylcellulose vinyl polymers, e.g., polyvinyl alcohol and polyvinylpyrrolidone
Film coating | SEPPIC
The film-coating formulation combines four key ingredients: A film-forming polymer, which provides the mechanical strength of the film. The most widely used polymers in non-functional film coating are cellulose derivatives such as hypromellose. Plasticizers, used to improve the flexibility of the film formed and prevent it from cracking or
Gelatin and Non-Gelatin Capsule Dosage Forms - PubMed
Shell component is an essential part of capsule dosage forms. 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.
Film Coating - an overview | ScienceDirect Topics
Film coating owes its success for these reasons: 1. Results is minimal weight increase (typically 2%–3% of tablet core weight), unless there is a need to achieve a modified-release effect. 2. Reduces processing times. 3. Increases process efficiency and output. 4. Exhibits formulation flexibility. 5.
Plasticizer Excipients - CD Formulation
DEHP (bis (2-ethylhexyl) phthalate) is a commonly used plasticizer. It is very toxic in small doses, but long-term large-scale exposure can cause many health problems. Many tablets have film coating. This is to protect the active ingredients in the tablet. A layer of coating separates the tablet core from the outside air and humidity.
- 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 .
- 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.
- Which film forming agents does BASF offer?
- BASF offers film-forming agents including coalescents, open-time prolongers and plasticizers. Our portfolio focuses on highu0002performance and sustainable products with renewable content that are non-phthalate and have lowest-possible VOC emissions in systems ranging from paints to plasters and sealants.
- 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 .
- Why is polymer-plasticizer incompatibility important?
- Compatibility between a polymer and a plasticizer produces stable and homogeneous coating film. It is often characterized by a high miscibility between the plasticizer and the polymer blend. Polymer-plasticizer incompatibility influences not only the mechanical properties but also drug release , .
- What is sorbitol special plasticizer?
- Effect on finished product's physical and chemical stability Sorbitol Special plasticizers are the original sorbitol-based softgel plasticizers. Their superior plasticizing effect results in shorter capsule drying time and inhibited blooming.
