Phthalate Esters in the Environment: Sources and Quantification
Phthalate esters are industrial chemicals used widely as plasticizers to impart flexibility and durability to polymers and plastics. Phthalates represent 69% of plasticizer used in USA, 92% in Western Europe and 81% in Japan [1]. Table 1 contains some of the 18 commercial phthalate esters.

Phthalate Ester - an overview | ScienceDirect Topics
Phthalate acid esters (PAEs) are a class of chemical compounds widely used in different industrial applications, mainly as plasticizers for polyvinyl chloride (PVC) resins, adhesives and cellulose film coatings and with minor applications in cosmetics, medical products and insecticide carriers.
Identifying Citric Acid Esters, a Class of Phthalate Substitute
Citrate acid esters (CAEs) have been proposed as a class of phthalate substitute plasticizers; however, information on their occurrence in indoor environments is rare.
Environmental impact of phthalic acid esters and their removal
The most common monomeric plasticizers are esters derived from phthalic acid, although others are derived from different organic acids, such as phosphates, trimetillates, citrates, sebacates, and adipates, among others (Titow, 1990; Wickson, 1993). The content of phthalate in a finished plastic product ranges from 10 to 60% by weight (IARC, 2000).
- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
- What is the structure of phthalate plasticizers?
- The structure of phthalate plasticizers is that of a phthalate ester, which is simply a phthalate with, an ester group (see structure below figure 1) (1). (Figure 1.) Phthalate plasticizers are colorless liquids like vegetable oil with a faint odor, and they are insoluble in water.
- What phthalate replacements does hallstar offer?
- Hallstar has a broad product portfolio with a wide range of functionality in both elastomers and PVC. A subset of this brand is our Plasthall® PR-Series which represents the group of products designed as phthalate replacements. Plasthall ® 114 is a proprietary, aliphatic ester plasticizer used to modify high-polarity thermoplastics and elastomers.
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.
- Is plasthall a polymeric or monomeric plasticizer?
- Ester plasticizers are typically monomerics, but those designated as Plasthall® P-Series are polymerics. Hallstar has a broad product portfolio with a wide range of functionality in both elastomers and PVC. A subset of this brand is our Plasthall® PR-Series which represents the group of products designed as phthalate replacements.
