What is Trimethyl Pentanyl Diisobutyrate?
Trimethyl Pentanyl Diisobutyrate (CAS 6846-50-0), commercially known as TXIB, is a non-phthalate plasticizer and coalescing agent.
Where is Trimethyl Pentanyl Diisobutyrate used?
- PVC compounding: secondary plasticizer and processing aid
- Flooring, wall coverings and coated fabrics: improves flow and flexibility
- Personal care: emollient in sunscreens and foundations, reduces tackiness and improves spreadability
- Waterborne coatings and latex: coalescing agent that lowers minimum film formation temperature
- Fragrance delivery: carrier that extends scent retention through low volatility
- It reduces reliance on regulated phthalate plasticizers while maintaining performance in flexible polymer systems.
Commercial specifications
- Drum and IBC quantities
- Personal care-grade material meeting purity specifications from select suppliers
