Arabinogalactan

Arabinogalactan (CAS 9036-66-2), also marketed under the trade name FiberAid and approved as E409, is a naturally derived polysaccharide extracted primarily from larch wood. It functions as a dietary fiber source and prebiotic agent.

This multifunctional texturizer is used across food, pharmaceutical, and personal care manufacturing. In food and beverage formulations, it acts as a low-viscosity bulking agent and fiber-enrichment ingredient for various products.

It enables high inclusion rates without significantly altering product texture or mouthfeel. Pharmaceutical manufacturers use it as a tablet binder and excipient, and it is increasingly incorporated into immune-support dietary supplements.

Due to its prebiotic classification, it is a popular choice for gut health formulations. In personal care, it improves skin feel and moisture retention in serums, creams, and leave-on treatments without adding heavy viscosity.

Agricultural applications include its use as a carrier and dispersant in crop protection formulations. This improves the delivery of active ingredients while maintaining stability in diverse environmental conditions for industrial use.

The product is supplied as a free-flowing white to off-white powder. It is available in food-grade and USP-compliant specifications, with FCC-grade material commonly sourced for dietary supplement and functional food applications.

Bulk quantities are standard for industrial buyers requiring consistent supply chains. Documentation typically includes certificates of analysis aligned to prebiotic fiber content specifications and relevant safety data sheets.
