Diisooctyl 1,2-cyclohexanedicarboxylate (DCB, CAS 84-71-9, EINECS 201-554-8, molecular formula C24H44O4) is a liquid plasticizer supplied at 99% purity. The key values in its technical data sheet are content ≥99.0%, specific gravity 0.950–0.965 g/cm³ at 20°C, color ≤15 Pt-Co, acid value ≤0.1 mg KOH/g, flash point ≥190°C and phthalate content ≤0.01%.
DCB is a cyclohexanedicarboxylate ester plasticizer. It is a clear liquid at room temperature with a density of 0.959. Compared with traditional phthalate plasticizers, DCB is manufactured with a phthalate content of ≤0.01%, which makes it a common reference when a low-phthalate plasticizer profile is required.
In flexible PVC and other plastic compounding, DCB is evaluated for its stable specific gravity (0.950–0.965 g/cm³ at 20°C), low acid value (≤0.1 mg KOH/g) and high flash point (≥190°C). These values support predictable dosage, good batch consistency and safer handling during compounding.

These are the typical values for this DCB grade. Actual batch values should always be confirmed against the certificate of analysis provided by the supplier.
Purity 99% and content ≥99.0% – two independent indicators of the ester quality supplied in this grade.
Phthalate content ≤0.01% – a low phthalate specification for applications where phthalate levels need to be controlled.
High flash point (≥190°C) – supports safer handling, storage and processing conditions.
Low acid value (≤0.1 mg KOH/g) – a routine indicator of batch stability and consistency.
Stable specific gravity (0.950–0.965 g/cm³ at 20°C) – enables accurate dosage calculation in compounding.
DCB plasticizer is referenced in our technical documentation for three application groups: plastic packaging, wire and cable, and foam and sponge. In each group, DCB is evaluated together with the whole compound recipe, the processing conditions and the performance requirements of the finished part.
Plastic packaging (reference application). Plastic packaging is listed as a reference application in the product documentation for DCB. Customers evaluating DCB for packaging-related compounds should confirm suitability against their own process requirements and applicable regulations.
Wire and cable. In wire and cable compounds, the high flash point (≥190°C), low acid value and low phthalate content of DCB are commonly reviewed during formulation work.
Foam and sponge. For foam and sponge systems, the liquid state and consistent specific gravity support uniform metering and dispersion during mixing.
See the High-Purity DCB Plasticizer for Plastic Packaging product page for the full product description and current availability.
DCB plasticizer is diisooctyl 1,2-cyclohexanedicarboxylate with CAS number 84-71-9, EINECS number 201-554-8 and molecular formula C24H44O4.
This grade is supplied at 99% purity with content ≥99.0%, shown as two separate rows in the technical data sheet.
No. The phthalate content of this DCB grade is ≤0.01%, and it is a cyclohexanedicarboxylate ester rather than a phthalate ester.
DCB is referenced for plastic packaging, wire and cable, and foam and sponge applications in the product technical documentation.
The flash point is ≥190°C and the specific gravity at 20°C is 0.950–0.965 g/cm³, with a density of 0.959.
TDS values such as acid value ≤0.1 mg KOH/g and color ≤15 Pt-Co are routine quality indicators; final performance should always be confirmed by formulation testing with the batch certificate of analysis.
DCB plasticizer offers a documented set of technical values – 99% purity, content ≥99.0%, flash point ≥190°C and phthalate content ≤0.01% – that make it a practical reference material for plastic packaging, wire and cable, and foam and sponge applications.
