Description

Starch Sodium Octenylsuccinate is a modified starch derivative, specifically the sodium salt of the octenylsuccinic ester of starch. This compound is valued for its exceptional emulsifying, stabilizing, and encapsulating properties, making it a key functional ingredient in industries where oil-in-water emulsions are critical. It is primarily sought after by manufacturers in the food, beverage, and pharmaceutical sectors for its ability to improve product texture, shelf-life, and active ingredient delivery.

Application

• Food & Beverage Industry: As a highly effective emulsifier and stabilizer in salad dressings, sauces, beverage clouds, and flavor emulsions.
• Encapsulation Agent: For microencapsulating sensitive oils, flavors, vitamins (like Vitamin A and D), and colors to protect them from oxidation and degradation.
• Pharmaceuticals: Used as an excipient in tablet formulations and for the encapsulation of active pharmaceutical ingredients (APIs).
• Personal Care & Cosmetics: Functions as a stabilizer and texture enhancer in lotions, creams, and other emulsion-based products.
• Industrial Applications: Acts as a binder, adhesive, or surface sizing agent in paper and textile manufacturing.
• Dietary Supplements: Employed in powder mixes and health drinks for its emulsifying and flow-aiding properties.

Quality Control

Our Starch Sodium Octenylsuccinate is manufactured under strict quality systems to ensure batch-to-batch consistency and compliance with relevant food and pharmaceutical standards. We offer grades compliant with FCC (Food Chemicals Codex) and can provide material suitable for applications requiring high purity. A comprehensive Certificate of Analysis (COA), detailing parameters such as assay, degree of substitution, and microbiological quality, is available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to prevent caking and degradation due to moisture absorption.
