Description

Aluminum Starch Octenylsuccinate CAS NO 9087-61-0 is a modified starch derivative where the starch molecule is esterified with octenylsuccinic anhydride and subsequently treated with aluminum. This modification imparts unique functional properties, making it a versatile ingredient. It is primarily valued for its excellent oil-absorbing, anti-caking, and texture-modifying capabilities. This product is essential for manufacturers in the cosmetics, pharmaceutical, and food industries seeking high-performance, multifunctional additives.

Application

• Cosmetics & Personal Care: Widely used as an oil-absorbing agent and texture enhancer in facial powders, foundations, blushes, and dry shampoos to reduce shine and improve feel.
• Pharmaceuticals: Serves as a glidant and anti-caking agent in tablet and powder formulations to improve powder flow and processing.
• Food Industry (where approved): Functions as an anti-caking agent, emulsifier, and stabilizer in powdered food products, seasonings, and dessert mixes.
• Industrial Applications: Used as a matting agent and rheology modifier in certain coatings, paints, and adhesive formulations.
• Topical Preparations: Employed in medicated powders and ointments for its absorbent and skin-adherent properties.

Quality Control

Our Aluminum Starch Octenylsuccinate is manufactured under strict quality management systems. Each batch is tested to ensure it meets specifications for key parameters such as aluminum content, particle size distribution, pH, and loss on drying. We can supply material compliant with relevant standards for cosmetic and pharmaceutical applications. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and consistent quality.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
