Professional R&D and excellent quality plasticizer chemicals

The plasticizer composition includes a first plasticizer comprising epoxidized fatty acid alkyl esters and a second plasticizer comprising an epoxidized natural oil. The plasticizer composition, first plasticizer, and/or second plasticizer can undergo one or more color-reducing treatment processes, such as distillation, filtration, and/or

The method of any of claims 8-13, wherein said plasticizer composition has an APHA value that is less than the APHA value of an identical reference plasticizer composition that has not undergone any of said color-reducing treatment processes of step (b) upon heat aging both said plasticizer composition and said reference plasticizer composition

One embodiment is a plasticizer composition comprising: a first plasticizer comprising epoxidized fatty acid alkyl esters; and a second plasticizer comprising an epoxidized natural oil, wherein said first plasticizer comprises fatty acid dimers in a concentration of less than 0.1 weight percent based on the entire weight of said first plasticizer.

Abstract. The invention relates to a plasticizer composition comprising a terephthalic acid di-ester and an ester having the following formula (I): wherein R 1 and R 2 are the same or different and represent a straight chain, branched or cyclic hydrocarbyl group. R 1 and R 2 in formula (I) have from 1 to 15 carbon atoms.

[0006] Another embodiment is a method for producing a treated plasticizer, said method comprising: (a) combining a first plasticizer and a second plasticizer to thereby form a plasticizer composition, wherein said first plasticizer comprises epoxidized fatty acid alkyl esters, wherein said second plasticizer comprises an epoxidized natural oil; and
