It is documented as a wetting agent across industrial, cosmetic, and food applications and as a dispersant, emulsifier, and stabilizer for hydrophilic colloids.

Frequently Asked Questions

What is docusate sodium used for in industrial applications?

Docusate sodium (DOSS, CAS 577-11-7) is an anionic surfactant — the sodium salt of dioctyl sulfosuccinate — documented as a wetting agent across industrial, cosmetic, and food applications, and as a dispersant, emulsifier, and stabilizer for hydrophilic colloids. It is also used as a processing aid in the sugar industry. RawSource supplies the granular USP 85% grade in bulk to manufacturers.

What does "granular USP 85%" mean for docusate sodium?

Granular indicates the physical form (free-flowing granules rather than a liquid or wax), USP indicates the material meets United States Pharmacopeia specifications, and 85% indicates the docusate sodium active content, the balance being typically water and processing carriers. Confirm the exact assay basis on the CoA against your specification at order.

Is docusate sodium a wetting agent or an emulsifier?

It functions as both, plus as a dispersant — it is a versatile sulfosuccinate surfactant valued for rapid wetting and for stabilizing emulsions and hydrophilic colloids. Which role dominates depends on your formulation and dose. RawSource can advise on grade selection for your application.

What is the CAS number and HS code for docusate sodium?

The CAS number is 577-11-7, the molecular formula is C20H37NaO7S, and it classifies under HS 3402.39 (anionic organic surface-active agents, other). RawSource provides a CoA and SDS with each bulk shipment to confirm identity, grade, and active content.

What is the cost of bulk docusate sodium granular USP 85%?

Pricing is quoted by order based on grade, volume, packaging, and freight. Send RawSource your target quantity and destination for a landed quote and lead time. We quote rather than list because cost tracks feedstock and order scale.
