Film Formers & Plasticizers for Tablet | Pullulan Applications
Pullulan has excellent binding strength and film forming properties, which makes it suited for tablets and granules. It is also used as an additive for solid oral dosage forms (Ex: Binder, Tablet coating, Granulation? Ingredient (s): Pullulan Dosage Form: Tablet Category: Film Formers & Plasticizers Route of Administration (Grade): Oral
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.
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.
Plasticizer Excipients | American Pharmaceutical Review
Plasticizers are used mainly for oral solid dosage forms. Plasticizers are added to the polymers used as film forming agents in order to make the polymer pliable and soft, enhancing the flexibility and plasticity of the films.
- What is film coated tablet?
- Development of film coated tablet has based on different types of polymer in various organic solvent system, aqueous system or hydro alcoholic system to prepare pharmaceutical solid dosage form. Film coating are dry blend of polymer, plasticizer and surfactants. A polymer used for film coating of tablets has great importance.
- What are plasticizers used for?
- Plasticizers are additives that increase the plasticity or fluidity of a material. Coating formulations based on physically drying binders such as nitrocellulose, require external plasticizers for optimal film formation. They are used to control the film formation process of coatings based on physically drying film-forming materials.
- What plasticizers are used in film coating?
- This reaction results in increased film flexibility and reduced residual stresses within the coating as it shrinks around the core during drying. Examples of plasticizers commonly used in film coating processes include: Polyols, such as glycerol (glycerin), polyethylene glycols (PEG 200 – 6000 grades) and propylene glycol.
- Can plasticizers be used in coating formulations?
- For natural products or hard polymers of poor processing, the option is the external use of plasticizers in the coating formulations. Plasticizers interact physically with the polymer binder molecule, without a chemical reaction and form a homogeneous system.
- 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 should a film-coated tablet look like?
- Schematic representation of the film-coating process Film-coated tablets should have even coverage with uniform colour coverage across the surface of each dosage unit within a batch, and from batch to batch. Film-coated tablets must be free from defects which affect functionality and stability of the finished product.
