Natural-based plasticizers and biopolymer films: A review
The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.

In this study, for the first time, Brazil nut seed oil was chemically modified with maleic anhydride to obtain maleinized Brazil nut seed oil (MBNO). The same process was developed to obtain maleinized hemp seed oil (MHO). The use of MBNO and MHO was studied as bio-based plasticizers by incorporating them with different contents ranging from 0 to 10 phr in a polylactic acid (PLA) matrix. By
Plasticizers – Benefits, Trends, Health, and Environmental Issues
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.
Biobased Plasticizers from Tartaric Acid, an Abundantly Available
Various efforts for producing more eco-friendly plasticizers have been carried out by using biobased sources such as diester succinates, which display better biodegradation behavior and...
Plasticizer | Article about Plasticizer by The Free Dictionary
1. An additive that increases plasticity of a cement paste, mortar, or concrete mixture. 2. An additive in a paint formulation to soften the film, thus giving it better flexibility, chip resistance, and formability. 3. A chemical agent added to a plastic composition to improve its flow and processability and to reduce brittleness.
- How do plasticizers work?
- It was commonly thought that plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing the "free volume"), or swelling them and thus significantly lowering the glass transition temperature for the plastic and making it softer.
- What is a plasticizer in chemistry?
- The council of the IUPAC (International Union of Pure and Applied Chemistry) defined a plasticizer as “a substance or material incorporated in a material (usually a plastic or elastomer) to increase its flexibility, workability, or distensibility”.
- How do plasticizers affect processing?
- Plasticizers can influence processing by inducing lower viscosity, faster filler incorporation, easier dispersion, lower power demand and less heat generation during processing, better flow, improved release and enhanced building tack.
- Can plasticizers be used to make plastic products?
- The use of plasticizers for plastic products manufacture is not a new practice. Its application to modify polymer characteristics began in the 1800s. In these early days, manufacturers of celluloid or celluloid lacquers used natural camphor and castor oil for plasticization purposes, but these were unsatisfactory for many end uses.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- What are plasticizers for polymers?
- Plasticizers for polymers are either liquids with low volatility or solids. According to 2017 data, the total global market for plasticizers was 7.5 million metric tonnes.
