People have been using plasticisers (US: plasticizers) to make things soft and flexible for thousands of years. Water has been used to soften clay since the early evolution of man and oils are known to have been used centuries ago to plasticise pitch for waterproofing boats.

Modern plasticisers are similar and different at the same time – constituting a wide range of chemistries and molecules bringing high performance in a wide array of applications in a safe and sustainable manner. They are colourless and odourless liquids which cannot be simply treated as additives like pigments or fillers.  Today, over 85 percent of all plasticisers consumed in Europe are employed in flexible PVC applications, largely for the construction, automotive and wire & cable sectors. They are, in fact, major functional substances that transform the physical properties of PVC and other polymers creating a whole new world of flexible and durable finished articles for high performing applications.

Over the last 60 years more than 30,000 different substances have been evaluated for their plasticising properties. Of these, only a small number – approximately 50 – are today in commercial use after meeting the rigorous performance, cost, availability, health and environmental requirements which are imposed by the market, users and regulators. The most common plasticisers include esters such as adipates, azelates, citrates, benzoates, orthophthalates, terephthalates, sebacates, and trimellitates.  They are produced by reacting an alcohol (such as isononanol or 2-propylheptanol) with an acid such as phthalic anhydride, terephthalic acid, adipic acid, trimellitic anhydride to name a few of the common starting materials. Different alcohols and different acids will lead to plasticisers exhibiting different degrees of permanence, performance and compatibility with PVC.

Because plasticisers are so widely used, they have undergone extensive testing for possible health and environmental effects and are amongst the most widely researched of all chemical substances. In Europe, the safe use of plasticisers is enabled by REACH, the most comprehensive product safety regulation anywhere in the world.

Globally, more than eight million tonnes of plasticisers are consumed every year, of which European consumption accounts for over 1.3 million tonnes. Orthophthalates, due to their high degree of compatibility with PVC, are the most widely consumed plasticisers. As can be seen from these figures, major plasticisers are high volume commodity chemicals, which take decades and billions of Euros to achieve full commercial development.

In Europe, non-classified high-molecular weight orthophthalates make up for the majority of the plasticisers market followed by terephthalates and cyclohexanoates. However, DEHP still makes for almost 40 percent of the global consumption because it is still widely produced and used in China, India, and other parts of Asia, the Middle East, Africa and Latin America.
