Aluminum starch octenylsuccinate

Aluminum starch octenylsuccinate (CAS 9087-61-0) is a modified starch derivative produced by reacting octenylsuccinic anhydride-treated starch with an aluminum salt. It functions primarily as an absorbent, anticaking agent, and texture modifier.

This versatile ingredient is utilized across personal care, food, and pharmaceutical applications. In cosmetic formulations, it improves the slip and skin feel of pressed and loose powders, helping to absorb sebum and reduce shine.

It is frequently found in color cosmetics and dry shampoos to manage oil. Food manufacturers use it as an emulsifier and encapsulating agent, particularly for stabilizing flavor oils and fat-soluble ingredients in spray-dried powder systems.

In pharmaceutical solid dosage forms, it acts as a flow aid and anticaking agent, improving powder handling during tablet and capsule manufacturing. It also appears in topical formulations where controlled oil absorption is required.

The material provides a smooth, non-greasy finish for various skin applications. Aluminum starch octenylsuccinate is supplied as a fine white to off-white powder and is available in food-grade and cosmetic-grade specifications.

Product quality is typically aligned to FCC standards for food applications and relevant pharmacopeial or industry monographs for pharmaceutical use. Particle size and moisture content are key specification parameters.

Buyers should confirm these technical details with suppliers to ensure application fit. The chemical stability and functional properties make it a reliable choice for manufacturers seeking consistent texture and performance in their final products.
