What does plasticizer mean?
A plasticizer is an additive used to make a polymer softer, more flexible, and easier to process. It is especially important in polyvinyl chloride, or PVC, which is naturally rigid but can be transformed into flexible tubing, flooring, upholstery, toys, cable insulation, and many other products by adding plasticizer. The amount and type of plasticizer affect properties such as flexibility, durability, heat resistance, and the ability of the material to age. Its use is not limited to PVC; other polymers can also be plasticized. The term is chiefly spelled plasticizer in North America and plasticiser in Britain. Technical discussions may also address plasticizer content, migration into food or the environment, and the use of less volatile alternatives.
nounA substance added to a polymer, especially polyvinyl chloride, to increase its flexibility, softness, or ease of processing. Plasticizers are commonly used in products such as flooring, tubing, toys, and packaging.
- A substance that is mixed with a polymer to increase its flexibility, softness, or processability.
"The manufacturer reduced the amount of plasticizer in the tubing to make it firmer and more durable."
"Flexible vinyl flooring can contain substantial amounts of plasticizer."
"Regulators have investigated whether plasticizer can migrate from certain products into food or the surrounding environment."
The standard plural is plasticizers. The form can count individual types of plasticizer or refer collectively to the additives used in a material.
"Manufacturers must consider the safety of all plasticizers used in products intended for children."
Plasticizers are the chemical softeners that make rigid PVC flexible enough for tubing, furniture, toys, and medical equipment.

Where does plasticizer come from?
The word was formed from plastic and the suffix -izer, which denotes an agent or substance that performs a specified function. Its components ultimately derive from Greek plastikos, meaning “moulded” or “fitted for moulding,” from plassein, “to mould.” The chemical sense developed alongside the industrial use of additives to alter the flexibility and processing qualities of plastics.
How plasticizer is actually used
The spelling plasticizer is standard in North American English, while plasticiser is common in British English. In technical usage, the term may refer specifically to a liquid organic compound, although other substances can also function as plasticizing additives.
Easily confused with plasticizer
A plasticizer is an additive incorporated into a polymer, whereas plastisol is a liquid vinyl resin that can be formed or cast into solid plastic products.
