Starch Sodium Octenyl Succinate
Name: Starch Sodium Octenyl Succinate
Other Name: SSOS
Molecular Formula:(C6H10O5)n(C8H14O4)Na
CAS No.: 66829-29-6
Packaging: 1kg/bag/carton; 5kg/bag/carton; 20kg/bag/drum
Appearance:
This product is white to slightly yellow powder, flakes or granules. It is hygroscopic.
Quality Standard: In-house.
Features:
Starch sodium octenyl succinate is produced by the reaction between starch and octenyl succinic anhydride. The introduction of octenyl succinic acid groups into the starch molecular chain imparts both hydrophilic and hydrophobic properties, making it an amphiphilic compound with strong emulsifying effects. It exhibits good water solubility and stability in both cold and hot water.
Applications:
| Dosage form | Application | Usage Amount |
| Emulsion | Emulsion stabilizer | 0.5-5% |
| Oral solid dosage forms | Microcapsule wall material | Depends on the API |
| Injectable Solutions | Carrier material | As required by formulation |
| Solid Dosage Forms | Coating material, controlled-release carrier | As required by formulation |
Advantages:
■ Amphiphilic compounds with strong emulsifying effects and stable emulsification systems.
■ Compared to unesterified starch, it exhibits higher viscosity and greater stability.
■ It has good water solubility and stability in both cold and hot water.
■Non-toxic, odorless, and tasteless, ensuring high safety.
■Excellent Emulsifying Properties: Forms a robust film in oil-in-water emulsions, preventing aggregation of dispersed phases.
Incompatibilities
■Incompatible with strong oxidizing agents, which may degrade its structure.
■Performance may be affected under extreme pH conditions (pH < 2 or pH > 12).
Storage: This product is hygroscopic; it should be stored in a dry place in a tightly sealed container.
