Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications.

However, phthalates can disrupt the hormonal or endocrine system, which may cause pregnancy loss, infertility and harmful effects on the delivery of a baby. As a result, many manufacturers have replaced phthalates with chemicals such as DINCH, another type of plasticizer, but less is known about the effects of this chemical compound on humans.

Phthalates are a large class of organic molecules of the family of plasticizers, agents that intercalate in the chemical structure of macromolecules such as PVC which give the material the typical properties of the plastic substances. Some examples of characteristics dependent on the presence and quantity of phthalates into the plastic polymers
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.

Recently, some other plasticizers instead of phthalate plasticizers, such as biocompatible material and oligomer 17,18,19,20,21,22,23,24,25,26,27, have been reported without toxicity. However
- What are phthalate plasticizers?
- This makes them readily soluble in bodily fluids, such as plasma and saliva (1). Two good examples of phthalate plasticizers are DEHP ( Di-Ethylhexyl Phthalate), and DINP (Di-Isononyl Phthalate). DEHP has been the most commonly used, and is still the plasticizer of choice for all PVC medical and surgical products.
- Are phthalate plasticizers soluble in water?
- (Figure 1.) Phthalate plasticizers are colorless liquids like vegetable oil with a faint odor, and they are insoluble in water. They are however, miscible in mineral oil, hexane, and most organic solvents. This makes them readily soluble in bodily fluids, such as plasma and saliva (1).
- Are phthalate plasticizers safer than thioesters?
- It is interesting to note that phthalate plasticizers first entered the market as a safer alternative to thioesters. They have been in use for close to fifty years and, because of their applications in plastics used in the medical industry, have been thoroughly studied.
- What type of plasticizer is used in PVC?
- The specific type of plasticizer that is of concern to this report is the phthalate plasticizer. Phthalate plasticizers are the most commonly used plasticizers in PVC. The PVC polymer chains are attracted to one another, and therefore from a very rigid structure.
- Are phthalate plasticizers dangerous?
- Phthalate plasticizers have been found to be a health concern when found in direct contact with bodily fluids. Studies performed on laboratory animals have shown that there is direct evidence that certain phthalate plasticizers have a carcinogenic effect in vivo.
- What are phthalates used for?
- Phthalates are the most used molecules in many sectors of industrial production. Although their molecular structure is able to intercalate in the structure of many different polymers, plasticizers phthalates find their main use in combination to PVC, one of the most used plastic polymers in various sectors worldwide.
