Abstract
The invention provides a plasticiser composition which comprises: (a) a first plasticiser which is one or more compounds of general formula (I) wherein R1 and R2 each independently represent a straight or branched chain alkyl moiety comprising from seven to twelve carbon atoms; and (b) a second plasticiser which is a citrate ester; a plasticised polymer formulation comprising a polymer and the plasticiser composition; a plastics article comprising the plasticised polymer formulation; and a method for the preparation of the plasticiser composition to provide a plasticised polymeric formulation which can be stored for up to five weeks with an increase of viscosity of less than 300%.
