Waste Fatty Acid-Based Methyl Tetraglycol Ester Derived from Dimer Acid Manufacturing as an Efficient and Biodegradable Plasticizer for Poly(vinyl chloride). ACS Sustainable Chemistry & Engineering 2025 , 9 (40) , 13573-13581.
A potentially general approach to aliphatic ester-derived PVC
The safety of flexible polyvinyl chloride (PVC) materials is now being questioned, partially due to allegations that di-(2-ethylhexyl) phthalate (DEHP), the dominant PVC plasticizer, is an endocrine disruptor and a probable carcinogen. As sustainable alternatives, aliphatic ester-derived plasticizers feature

2O 3, SnO 2, TiO 2, ZrO 2, etc.) are of much interest as esteri cation catalysts. The acid-ity of such systems is very high, exceeding even that of 100% sulfuric acid. Yanfei et al. [15] analyzed the use of solid superacids, sulfonium anion-exchange resins, heteropoly acids supported on zeolites, ionic organome-
Synthesis of Biomass Based Plasticizer from Linoleic Acid and
In this paper, we synthesized a kind of bio-based plasticizer epoxidized linoleic acid cardanol ester (ELCE) from cardanol and linoleic acid. Its chemical structure was characterized with FT-IR and 1 H NMR. Polyvinyl chloride (PVC) blends plasticized with ELCE were prepared via thermoplastic blending with torque rheometer.
Plasticizers Derived from Biomass Resources: A Short Review.
Polyvinyl chloride (PVC) plasticizers derived from biomass resources (vegetable oil, cardanol, vegetable fatty acid, glycerol and citric acid) have been widely studied to replace petroleum-based o -phthalate plasticizers.
- Are ricinoleic acid esters a plasticizer?
- This study examines the plasticizing mechanisms by comparing three ricinoleic acid esters with different alkyl chain lengths to three commercial plasticizers, including dioctyl terephthalate (DOTP), epoxidized soybean oil (ESO), acetyl tri-n-butyl citrate (ATBC).

- What are the structural features of effective plasticizers?
- Several structural features of effective plasticizers have been recognized. Polar functionality is required to assure compatibility with a wide range of polymeric materials, including poly (vinyl chloride) (PVC), the most heavily plasticized polymer. A branched structure greatly enhances the effectiveness of compounds used as plasticizers.
- What is a nonmigrating plasticizer?
- Most prominently, hyperbranched oligomeric esters derived from the readily available, renewable, nontoxic biomonomers, glycerol and adipic acid, are excellent nonmigrating plasticizers. These materials may be produced in a simple process.
- Which phthalate is used as a plasticizer?
- Traditionally, phthalate esters, most prominently, di (2-ethylhexyl) phthalate [DEHP], have been used as plasticizers. DEHP is produced from two inexpensive precursors, phthalic acid and 2-ethylhexanol. Phthalic acid is obtained from the oxidation of o -xylene, the least useful of the mixed xylenes from the reforming of naphtha .
- Is liquefied wood flour ester a good plasticizer?
- The liquefied wood flour ester (PWF) showed good miscibility with PLA and good plasticization efficiency as shown by differential scanning calorimetry (DSC) and tensile testing. Tensile strain at break increased from a few percent for pure PLA to over 100 and 300% for the materials containing 10 and 30 wt-% of PWF.
