An example of the most common, general purpose plasticizer is DOP, dioctyl phthalate, also known as DEHP, or diethylhexyl phthalate. This plasticizer is most commonly seen in PVC, but can be found in other polymer systems as well. General purpose plasticizers primarily impart flexibility to a polymer and improve its workability.
An example of a specialty plasticizer would be dipropylene glycol dibenzoate. This plasticizer is often found in PVC as well as many other polymer systems including acrylates and urethanes. Specialty plasticizers also impart flexibility but have the added benefit of special properties, such as improving gloss, imparting better low temperature flexibility, faster fusion, etc.
Plasticizers are typically esters of some type. Some examples of general classes of plasticizers include:
phthalates
benzoates
adipates
citrates
trimellitates
The "original" plasticizer was camphor, which was phased out during the early 20th century with the discovery of phthalates.

Why is ethyl acetate used as plasticizer?
Ethyl acetate is a solvent that can help increase the flexibility and durability of certain plastics. It is used as a plasticizer to improve the material's ability to bend without breaking, making the plastic more suitable for various applications. Additionally, ethyl acetate is relatively easy to work with and is cost-effective compared to other plasticizer options.
Why ethyl acetate used as a plasticizer?
Ethyl acetate is not typically used as a plasticizer in plastics. It is more commonly used as a solvent in coatings, adhesives, and inks due to its low toxicity and pleasant odor. Plasticizers are usually substances like phthalates or adipates that are added to plastics to improve flexibility and durability.
What is Triethyl Citrate?
Triethyl citrate is a colorless, odorless ester of citric acid. It is commonly used as a food additive and plasticizer in various products such as pharmaceuticals, food packaging, and personal care products due to its non-toxic and biodegradable nature.
What is the chemical equation of nitrocellulose and plasticizer in nail polish?
The chemical equation for the ingredients in nail polish, nitrocellulose, and plasticizer, is not a simple equation, as it involves more complex interactions and polymer formations. Nitrocellulose is a polymer made from cellulose nitrate, while plasticizers are compounds added to make the nitrocellulose flexible and adhesive. Together, they form a film that provides the desired properties to nail polish.
What is the chemical structure of polymer clay?
Polymer clay is composed of polyvinyl chloride (PVC) particles suspended in a plasticizer. When heated, the PVC particles fuse together to form a solid plastic. Additional ingredients such as pigments and fillers can be added to achieve desired colors and properties.
