Release Enhancement by Plasticizer Inclusion for Amorphous
Glycerol derivatives and citrate plasticizers were evaluated in terms of their ability to increase the LoC of ASDs containing the high Tg compounds, atazanavir and ledipasvir. Ritonavir, a lower Tg compound, was used as a control. The polymer employed for the ASDs was polyvinyl pyrrolidone vinyl acetate (PVPVA).
AQUACOAT ECD: CRITICAL FORMULATION ATTRIBUTES OF PLASTICIZER
order of plasticizers is ATEC > DEP > TBC > DBP > ATBC > DBS: in other words, a plasticizer with comparatively high water-solubility, such as DEP, shows a higher rate constant and faster plasticizer uptake than the water-insoluble DBS. Various studies have also been carried out to predict mass transfer of different plasticizer types
Effect of TBC Plasticization on Thin Polycarbonate Sheet
performance and structure of the novel plasticized thin PC sheets with the pure “green” TBC plasticizer under different time period and temperature. Here, we ultimately chose TBC as PC plasticizer based on two reasons: the most important reason is that plasticizer TBC is a less-toxic plasticizers and it is
The molecular mechanisms of plasticizers in rejuvenating
The two plasticizers selected for evaluation in this study were dibutyl phthalate (DBP) and tributyl citrate (TBC), both with a purity of 99 % and purchased from . DBP is an important plasticizer that is used to manufacture everyday products such as polyvinyl chloride, printing inks, and adhesives

High-performance stabilizer for monomers Applicable to manufacturing processes, transportation and storage Available in a variety of forms and solvent-based grades Plasticizers DIC’s offers various grades of plasticizers for automotive, industrial and household uses. Key attributes and features:
- Is tributyl citrate a good plasticizer for polylactide and polyhydroxybutyrate?
- The effectiveness of tributyl citrate (TbC) as plasticizer for polylactide (PLLA) and poly (hydroxybutyrate) (PHB) was analyzed in order to improve the ductility of these polymers and make them good candidates for food packaging applications.
- Is TBC a phthalate plasticizer?
- ... In addition to DOIP, TBC is another non-phthalate plasticizer that was identified in two vinyl glove samples. TBC has been reported to be a safer alternative to phthalates and biocompatible plasticizers [58, 59].
- Does plasticizer tributyl citrate increase moisture permeability?
- Jost et al. (2014) studied the WVP as a function of the plasticizer type and concentration in the alginate cast films. Chaos et al. (2019) found that adding the plasticizer tributyl citrate would increase the moisture permeability of polylactide and polyhydroxy butyrate films.
- What is the oxygen permeability of PLLA and PHB plasticized with TBC?
- Oxygen permeability for PLLA and PHB plasticized with TbC. oxidation and the growth of aerobic microorganisms. T hese lead of toxic compounds. Therefore, the characterization of oxygen shelf life of food. ity coefficients). PLLA presents a value of 0.14 Barrer that is the ually with the addition of TbC. significantly with the amount of plasticizer.
- Is TBC a safe alternative to phthalates?
- TBC has been reported to be a safer alternative to phthalates and biocompatible plasticizers [58, 59]. It has numerous applications in the polymer industry, particularly for the synthesis of PVC polymers used for food contact materials . ... ...
- Which is better PLLA/TBC or PhB?
- Average cluster size for PLLA/TbC blends as a function of activity. plasticizer being more relevant for PHB. However, for the transport nounced than for the PLLA/TbC system. Furthermore PHB shows outstanding barrier properties despite the addition of plasticizer. with a better barrier character, PHB/TbC. In conclusion, the study
