  • What are natural based plasticizers?
  • Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
  • What are biodegradable plasticizers?
  • Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
  • How does plasticizer migration affect the quality and effectiveness of PVC?
  • The migration of plasticizers is a key factor that impacts the quality and effectiveness of the PVC, and the mass loss due to plasticizer migration in different environments is shown in Fig. 8.
  • Which plasticizer is best for chitosan film?
  • Besides, considering the plasticization efficiency and storage stability for chitosan films, GLY and PEG showed to be more suitable than EG and PG. Furthermore, a plasticizer concentration of 20% (w/w) with GLY or PEG was sufficient to obtain flexible chitosan film, exhibiting good stability for 5 months of storage.
  • Are biopolymers a good substitute for conventional plasticizers?
  • The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
  • 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.
