Diverging trends of plasticizers (phthalates and non-phthalates)
LMW phthalates are characterized by up to six carbon atoms in the main chain [ 70 ]. Furthermore, the demand for alternative plasticizers is increasing. Today, the most frequently used non-phthalates are adipates, terephthalates (main representative DEHT) and Diisononyl 1, 2-cyclohexanedicarboxylic acid (DINCH) [ 60 ].

Alternatives to LMW Phthalate Plasticizers for PVC: Selection & Use On-Demand Course Recorded on Mar 2, 2025 Formulation (62 ratings) Implement a well-defined methodology to select the right alternatives for phthalates (low-molecular weight) that cater to the stringent health & environmental regulations.
Phthalate Risks and Alternatives | Center for Advanced Life Cycle
Some of the most common phthalates found in PVC applications include DEHP, DBP, DEP, and DiNP. DEHP was historically the most commonly used phthalate for plasticizing PVC, but in 2015 it was banned in most product applications in Europe due to concerns over its endocrine-disrupting potential.
Chemists develop safe alternatives to phthalates used in plastics

Diverging trends of plasticizers (phthalates and non-phthalates)
the phthalate plasticizers from LMW phthalates toward HMW phthalates [45]. LMW phthalates are character-ized by up to six carbon atoms in the main chain [70]. Furthermore, the demand for alternative plasticizers is increasing. Today, the most frequently used non-phtha-lates are adipates, terephthalates (main representative
- Are there alternatives to phthalate plasticizers?
- CALCE has been being interested in the performance and reliability of newly alternative materials, which are aligned to the legislations, and proposed potential alternatives to phthalate plasticizers, including bio-based substitutes and thermoplastic elastomers.
- Are there alternatives to DEHP in plasticizing and processing PVC?
- The alternatives need to maintain the high performance characteristics of DEHP in plasticizing and processing PVC while not inducing adverse effects on living organisms. Phthalates containing different aliphatic substituents were scrutinized first due to their structural similarities with DEHP.
- What is a non Phthalate plasticizer?
- There are a number of non-phthalate plasticizers on the market, often offering an alternative to meet special requirements in flexible PVC. For example, adipates offer low temperature flexibility and low viscosity, while trimellitates offer particular advantages in high temperature cable sheathing applications.
- What phthalate is used in PVC plasticizers?
- The most widely used PVC plasticizers are phthalate esters, particularly di- (2-ethylhexyl) phthalate (DEHP), which usually represent up to 40–50% of the weight of the plastic items. Phthalates account for 80% of all plasticizer production while DEHP is responsible for over 50% of worldwide phthalate production .
- Why do phthalates and alternative plasticizers have different mass-transfer characteristics?
- As SVOCs have significant partition capacities on gas-solid interfaces, phthalates and alternative plasticizers exhibit mass-transfer characteristics that differ from other pollutants, such as volatile organic compounds and nanoparticles, which have smaller and larger molecular weights, respectively.
- Why do alternative plasticizers have lower dust-phase concentrations than phthalates?
- The lower dust-phase concentrations of alternative plasticizers compared to phthalates may be attributed to their larger molecular weight , , . As listed in Table 1, alternative plasticizers generally have larger molecular weights, which correspond to lower vapor pressures and lower y0 on source surfaces.
