Effectiveness of triacetin and triethyl citrate as
It was found that, at a fixed amount of plasticizer (10%), TRI caused reduction of glass transition temperature (Tg) and melt temperature (Tm) in both PVA with the largest reduction in 88% hydrolysed PVA while TEC showed insignificant changes of Tg and slight reduction of Tm suggesting higher effectiveness of plasticization in 88% hydrolysed PVA
Glycerol and triethyl citrate plasticizer effects on
Although promising the use of CA as packaging, this material requires the addition of processing aids, such as plasticizers. This work aimed to optimize the plasticizer effect of glycerol (GLY) and triethyl citrate (TEC), in different concentrations (1.8, 3.6, 5.4, and 7.2 mol), added into the CA.
Biobased additive plasticizing Polylactic acid (PLA) S
The reason for good solubility of citrate plasticizers in PLA is due to the polar interactions between the ester groups of PLA and the plasticizer[20]. Two biodegradable, nontoxic plasticizers that have been successfully blended with PLA are triethyl citrate (TEC) and acetyl tributyl citrate (ATBC). At the concentrations used
Triethyl citrate = 98.0 GC 77-93-0 - Sigma-Aldrich
Triethyl citrate was used as a plasticizer in the study of the feasibility of near-infrared (NIR) spectroscopy in determining the influence of plasticizer levels and sintering temperature on the breaking force of extended-release matrix tablets prepared by roller-compaction [ 2].

Citrates - Polymer Additives Selection
Plasticizers > Citrates. When added to polymers, citrate plasticizers offer good performance and excellent flexibility at low temperatures; being less volatile, they also offer good heat and light stability. Catagorised as non phthalates, citrates are ideal to be used in medical device, food packaging applications and pharmaceutical preparations.
- Can glycerol and triethyl citrate improve plasticizer effect?
- This work aimed to optimize the plasticizer effect of glycerol (GLY) and triethyl citrate (TEC), in different concentrations (1.8, 3.6, 5.4, and 7.2 mol), added into the CA. The films were characterized using mechanical strength tests, FTIR, TGA, SEM, and various other analysis technologies.
- Is acetyl citrate a plasticizer?
- ... Citrate esters such as triethyl citrate (TEC) and acetyl tributyl citrate (ATBC) have been widely used as plasticizers in PLA formulations, exhibiting excellent ductile properties. Maiza et al. reported plasticized PLA formulations with up to 30 wt.% TEC or ATBC with a noticeable decrease in the glass transition temperature (T g ).
- Why are citrate plasticizers soluble in PLA?
- The reason for good solubility of citrate plasticizers in PLA is due to the polar interactions between the ester groups of PLA and the plasticizer . Two biodegradable, nontoxic plasticizers that have been successfully blended with PLA are triethyl citrate (TEC) and acetyl tributyl citrate (ATBC).
- Can glycerol and triethyl citrate be used as packaging materials?
- Although promising the use of CA as packaging, this material requires the addition of processing aids, such as plasticizers. This work aimed to optimize the plasticizer effect of glycerol (GLY) and triethyl citrate (TEC), in different concentrations (1.8, 3.6, 5.4, and 7.2 mol), added into the CA.
- What is triethyl citrate (TEC)?
- Triethyl Citrate (TEC) is a widely used plasticizer that imparts flexibility and durability to various polymers, particularly in applications such as films, coatings, and resins. It enhances the processability and performance of the materials. TEC is considered non-toxic and safe for use in consumer products.
- Why is triethyl citrate used as a plasticizer?
- The addition of only 10% w/w triethyl citrate as plasticizer improved the flexibility of the films significantly and allowed compaction of the pellets. The drug release was almost independent of the compression force and the pellet content of the tablets.
