Health, Eco Concerns Give Non-Phthalate Plasticizers a Push
DOTP and Hexamoll DINCH are two leading non-phthalate alternatives gaining significant ground. DOTP from Eastman has been available for several decades as Eastman 168, and the company claims it is the market-leading non-phthalate plasticizer for PVC, offering performance equal to or better than most non-phthalates.
Plasticizer Makers Want A Piece Of The Phthalates Pie

What is the best alternative to DEHP for medical-grade PVC
In addition, TOTM is a much less efficient plasticizer than DOTP, meaning you have to use more TOTM to achieve the same durometer—and plasticizer today is more expensive than PVC resin. Purity. If processed in truly dedicated equipment, DOTP can be produced nearly free of DEHP contamination.
PVC Plasticizers and Stabilizers Following Safer Sustainable
Traditional low molecular weight plasticizer types include: DEHP (DiEthylHexylPhthalate) DIBP (DiIsoButylPhthalate) DBP (DiButylPhthalate), and BBP (BenzylButylPhthalate) High molecular weight orthophthalates and alternative bio-based plasticizers are the emerging replacement choices.
Bis(2-ethylhexyl) terephthalate
Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl.
- Do alternative plasticizers metabolize phthalates and DINCH?
- For instance, the human metabolism of phthalates and DINCH is well known. Therefore, exposure to these substances can be well assessed by measuring relevant metabolites in human matrices like blood or urine. Unfortunately, this has not been done for all relevant alternative plasticizers.
- Are alternative plasticizers safe?
- Toxicity profiles were extensive but still showed data gaps, mostly regarding carcinogenicity and endocrine disruption (Table 1 A). According to current knowledge, the use of alternative plasticizers seems to be of low risk for humans as calculated risk ratios were mostly well below 1.
- Where can I find toxicological data for alternative plasticizers?
- For all selected alternative plasticizers, toxicological information is available to a certain extent. Since these substances are produced in high volumes, toxicological data are required in the EU and could be found in the ECHA database for registered substances (ECHA, 2014b).
- What are alternative plasticizers?
- Extensive research has been performed to identify alternatives for PEs. Currently, many different alternative plasticizers exist including adipates, benzoates, citrates, cyclohexane dicarboxylic acids, epoxidized vegetable oils, glycerol acetylated esters, phosphate esters, sebacates, terephthalates and trimellitates.
- Are there alternative plasticizers in Sweden?
- There is an increasing trend in the total use of alternative plasticizers in Sweden compared to common phthalate esters in the last 10 years, especially for DINCH. Evaluative indoor fate modeling reveals that most alternatives are distributed to vertical surfaces (e.g. walls or ceilings).
- Are there alternative plasticizers in the indoor environment?
- Generally, alternative plasticizers can be expected in various exposure matrices in the indoor environment, although only very few exhibit strong partitioning to indoor air. Instead, it is likely that many alternatives will be detected in dust and/or food due to their low volatility and relatively high hydrophobicity.
