Abstract
The present invention refers to a composition comprising tetrahydrofurfuryl and alkoxylated alkyl esters and their use as plasticizers in biodegradable resins, more in particular, in a biodegradable aliphatic polyester resin comprising polylactic acid. In a preferred embodiment the composition comprises a tetrahydrofurfuryl butyldiglycolate ester. The invention also refers to a biodegradable resin composition, more in particular, comprising homo- or co-polymers of polylactic acid and comprising such compositions.
