Nontoxic bio-plasticizers for PVC as replacements for conventional
The most common bio-based plasticizer is epoxidized soybean oil (ESBO) [24,25, 84, 85], which is also used as a heat stabilizer in PVC blends because of its ability to scavenge HCl molecules...
Effect of acetylated citrate plasticizer on mechanical properties
The total quality of citrate and PVC was controlled at 15 g, and the mass proportion of citrate was 20 wt%, 30 wt %, 40 wt %, 50 wt % and 60 wt %, respectively (Table S1).

Effectiveness of triacetin and triethyl citrate as plasticizer
PVA is a non-toxic polymer with abundant of hydroxyl functional groups which can be synthesized from the hydrolysis of polyvinyl acetate [1]. Depending on the degree of hydrolysis, PVA can be classified into two main groups, the partially and full hydrolysed PVA.
Levulinic Acid as a Versatile Building Block for Plasticizer Design
All DPT plasticizers have toxic doses of 5000 mg/kg and are non-toxic. These DPTs are potential to replace reproductive toxic phthalate plasticizers in food packaging materials, toys, and medical
Citrates - Polymer Additives Selection
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.
- What is the difference between PVC and toxic plasticizers?
- The combination of hydrogenated castor oil and epoxidized soybean oil based plasticizers shows comparable mechanical performance of that PVC to PVC with conventional toxic plasticizers.
- Can acetyl group replace hydroxyl group in PVC resin?
- MD simulation study found that the substitution of hydroxyl group with acetyl group cannot only destroy the hydrogen bond between citrate and PVC, accelerate the movement of polymer chain, increase the elasticity of PVC resin, but also reduce the binding ability of citrate and protein, and reduce its toxicity.
- What is a citrate plasticizer?
- Citrate plasticizers are made of citrates which are esters of citric acid. They can be found in oily liquid form and they are practically colourless and odourless. They are used in paints, coatings and inks but also in food packaging products, cling wrap, toys and medical applications.
- Which materials can be plasticized with citrates?
- Some properties of materials plasticized with citrates can match those plasticized with DOP but the cost of their production is substantially higher. Tri Butyl Citrate is a high boiling substance, is used as a solvent and plasticizer for polymers especially for PVC and its copolymers which are subsequently applied to food wrapping film.
- Which plasticizers are used in PVC based products?
- Citroflex™ in PVC Applications: Phthalate plasticizers, including DEHP, have been the primary plasticizers used in polyvinyl chloride (PVC) based products for many years.
- Which phthalate plasticizer is best for PVC based products?
- Phthalate plasticizers, including DEHP, have been the primary plasticizers used in polyvinyl chloride (PVC) based products for many years. Citroflex™ citric acid esters are excellent alternatives to phthalate-based plasticizers as they provide a better balance of physical properties and low volatility when used in PVC systems.
