Plasticizers in edible films and coatings - ScienceDirect

Lipid plasticizers such as fatty acids and derivatives, lecithin, oils, and waxes are also commonly used in edible coatings. Generally, the purpose of adding lipid is to reduce film water vapor permeability, since lipids are non-polar nature or hydrophobic, and thus provide a good barrier against moisture migration.

It is estimated that 3.5 million t of phthalate plasticizers for the PVC which are completely coming from fossil oil are consumed per year (Storey et al., 1989; Bocque et al., 2016). In addition, as persistent organic pollutants, the phthalate plasticizers pose potential threats to the environment and human health.

Consequently, when PVC compositions are plasticized with dicarboxylic acid esters, plasticizer efficiency directly depends on the number of methylene groups in the ester composition and on the infused plasticizer quantity. Dioctyl sebacate (DOS) is the best plasticizer for PVC polymers.

The liquid volume resistivity of plasticiser esters is improved by purifying the ester with an adsorbent having a pH in the range 6 to 11. It is preferable to use a mixture of a filtration aid and an adsorbent. A plasticiser having a desirable combination of high liquid volume resistivity, low amount of light ends and low carbonyl number is obtained.
