Plasticizer < Our Business | OCI
Plasticizers are categorized as phthalate-based, trimellitate-based, phosphoric acid-based and epoxy-based depending on the base material. It is produced by the ester reaction between alcohol such as Octanol (2-EH), INA, etc., and acids such as PA, TPA, TMA, etc. Depending on the base material, different grades of plasticizers are produced.
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
Film forming systems for topical and transdermal drug delivery
The solvent used in film forming systems help in solubilizing the drugs as well as have an impact on drug permeation. Commonly used solvents for topical and transdermal use [53] are listed in Table 6. As these solvents are widely used, the safety of these has been established on long term use. Table 6.
Gelatin soft capsule formulation
Method Blend the gelatin, plasticizers* and water in the melter. Heat until the gelatin melts (end point 60°C). Vacuum for full de-aeration. Maturate for minimum 6 hours** at 60°C. Process the melt through your softgel equipment, dry to mass constancy (typically tumble dryer followed by tray drier at 20% ERH /25°C).
Pharmaceutical Tablet Film Coatings | PharmaCentral
The polymer is the film former and the main component on the formulation. The ideal polymer is one capable of producing smooth, thin films that are reproducible under routine coating conditions. The range of materials that can be used as film formers is very wide and covers materials that may be natural, synthetic or semi-synthetic.
- 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.
- 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 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.
- Can bio-based plasticizers replace conventional plastic goods?
- The challenge to implement this new class of natural-based plasticizers matches the increasing interest of material researchers and industries in new bio-based materials, made from renewable resources with the potential, not to totally replace but to reduce the use of conventional plastic goods.
- 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 .
- Why do plasticizers soften polymers?
- Internal plasticizers generally have bulky structures that provide polymers with more space to move around and prevent polymers from coming close together. Therefore, they soften polymers by lowering the Tg and, thus, reducing elastic modulus.
