Topical Polymeric Films and Transdermal Patches | BASF Pharma
While topical polymeric films form intact, transparent drug delivery systems on the skin surface, transdermal patches utilize adhesive matrix technology to deliver active pharmaceutical ingredients through the skin. Due to their benefits such as physical barrier formation, ease of application, and reduced dosing frequency, topical polymeric
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt, the glass transition temperature (Tg), the melting temperature (Tm) and the elastic modulus of the finished product without altering the fundamental chemical character of the plasticized material.
Polymeric Plasticizers
Polymer plasticizers or polyadipates are polyesters of aliphatic dicarboxylic acids. BASF manufactures and markets the following polymer plasticizers for special applications: Palamoll products (polyesters of aliphatic dicarboxylic acids) Palamoll 632: Technical Information Palamoll 638: Technical Information
Polymers | Special Issue : Green Plasticizers for Polymers - MDPI
Consequently, industrial and academic attention has shifted towards using plasticizers which do not degrade into non-toxic metabolites, and the thrust into replacement plasticizers has been further shifted towards green plasticizers that not only have favourable leaching properties and degradation into non-toxic products upon disposal, but also
- What is a topical film forming system?
- Topical film forming systems are such developing drug delivery systems meant for topical application to the skin, which adhere to the body, forming a thin transparent film and provide delivery of the active ingredients to the body tissue.
- Why are plasticizers used in film forming systems?
- Plasticizers Plasticizers are used in the film forming systems to impart flexibility to the film and improve the tensile strength of the film formed. The plasticizer used should be compatible with the polymers used and should have low skin permeability.
- Are polymeric drug delivery systems plasticizers?
- Plasticizer as minor component of polymeric drug delivery systems has not been strictly defined. Even liquid drugs or liquids with a potential pharmacodynamic effect can serve as plasticizers. As well structural water in the hydrophilic polymer seems to be an internal plasticizer of the polymeric drug delivery systems.
- Are plasticizers used in transdermal drug delivery systems?
- In transdermal therapeutic systems. It is observed that the plasticizers added to transdermal therapeutic systems are mostly used in the proportions between 5-20%. Following are the reasons which can be counted among those for adding plasticizers to the polymer films to be used in transdermal drug delivery systems:
- Is hydrophilic polymer an internal plasticizer of polymeric drug delivery systems?
- As well structural water in the hydrophilic polymer seems to be an internal plasticizer of the polymeric drug delivery systems. In case of contact with body fluids after application the hydrophilic plasticizer can be released from polymer and thus conditions for the incorporated drug release are changed.
- 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 .
