Pharmaceutical Tablet Film Coatings | PharmaCentral
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.
Film coating | SEPPIC
Seppic develops effective and easy-to-use film coating agents for medications and dietary supplements, thanks to its expertise in film coating, and in selecting compositions based on a tablet’s type and desired functionality. The tablet coating process The coating process results in the formation of a thin layer of polymer around the tablet.
Film forming agents
Featured film forming agents for solvent based systems. 1. EFKA PL 5381. Standard epoxy plasticizer which is extraction-resistant to many industrial agents. The migration resistance is comparable with polymeric plasticizers. 2. EFKA PL 5382. Epoxy plasticizer that improves whiteness and resistance to ageing with food contact range.

Castor oil is primarily used as a base for organic solvent solutions; on the other hand, PEG and PG are commonly used for aqueous coating. External plasticizers must be soluble in the solvent that is used to dissolve the plasticizer and film. The film former and the plasticizer must however achieve at least partial mutual solublity in the solvent.

Sorbitol Special is an effective plasticizer for soft gel formulations which makes soft shells more robust. These grades reduce drying time, driving productivity and also enhance the gloss of capsules for a premium appearance. Ingredient (s): Sorbitan, Sorbitol Dosage Form: Softgels Category: Film Formers & Plasticizers
- Why are citrate plasticizers not used in film applications?
- However, citrate plasticizers are highly volatile and a significant amount is lost due to this property. Citrates lack permanency. Hence, they are not employed in resilient applications like cables, flooring, or roofing. They induce more fogging in film applications.
- What type of polymer is used to make a tablet?
- Polymers such as ethyl cellulose and altered acrylates are used. Tablets that are compressed are coated with sugar layer and may be colored or uncolored depending on the tablet’s purpose. The sugar coating is water-soluble making it easier to dissolve quickly
- What are bio-based plasticizers?
- As the name says, biobased plasticizers are majorly based on: Few more plasticizers are based on renewably sourced isosorbides and alkanoic acids. Isosorbide diesters are a non-toxic alternative to phthalates. They offer promising properties to PVC. Being naturally/renewable sourced, bio-based plasticizers are sometimes easily approved for:
- 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.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What phthalate plasticizers are most commonly used?
- Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. Made from aliphatic dibasic acids such as adipic acid and alcohols.
