Dibutyl Sebacate (DBS) Product Overview
Dibutyl Sebacate (DBS) is a castor-based sebacate ester produced by esterification of sebacic acid with n-butanol. It is widely used as a plasticizer, lubricant ester, and specialty additive due to its excellent low-temperature flexibility, compatibility, and stability.
DBS is typically selected where elasticity retention, smooth processing, and predictable ester performance are required across industrial and specialty formulations.
Manufacturing / Processing (High-Level)
Dibutyl Sebacate is manufactured through controlled esterification of sebacic acid, followed by purification and finishing. The process is designed to:
- Achieve high ester conversion
- Minimize residual free acid and alcohol
- Ensure stable viscosity and ester purity
Processing parameters are standardized to deliver consistent batch-to-batch performance.
Raw Material Origin
The product is derived from sebacic acid obtained from castor oil–based intermediates, sourced from Indian castor seeds. Raw material consistency directly influences ester clarity, stability, and functional behavior.
In-House Quality Control & Consistency
Quality control focuses on ester content, acidity, moisture, and appearance, which are critical for plasticizer and lubricant performance. Each batch is evaluated to maintain repeatable compatibility and processing behavior.
Batch documentation supports traceability and long-term supply reliability.
Key Properties (Indicative)
- Appearance: Clear, colorless to pale yellow liquid
- Odor: Mild, characteristic
- Solubility: Insoluble in water; soluble in organic solvents
- Functional behavior: Plasticizing efficiency, low-temperature flexibility
Typical ranges are indicative and should be confirmed with the Certificate of Analysis (COA).
