Frequently Asked Questions

What is sodium xylene sulfonate 40% used for?

Sodium xylene sulfonate (CAS 1300-72-7) is the sodium salt of xylenesulfonic acid, supplied here as a 40% aqueous solution. It acts as a hydrotrope that solubilizes surfactants and keeps concentrated liquid cleaners stable and clear, as a viscosity modifier in high-active liquids, and as a coupling agent in detergents, degreasers, leather glues, and textile printing pastes.

What does the 40% in sodium xylene sulfonate 40% mean?

It indicates the active content: the product is a roughly 40% active aqueous solution of sodium xylene sulfonate. This solution form is convenient for direct dosing into liquid detergent and degreaser formulations. The technical data sheet states the exact active range per lot.

Is sodium xylene sulfonate water soluble?

Yes. Sodium xylene sulfonate is highly water-soluble; as a hydrotrope its role is precisely to increase the water solubility of other surfactants and keep concentrated formulations clear. Refer to the SDS for handling information.

What is the CAS number for sodium xylene sulfonate?

Sodium xylene sulfonate carries CAS 1300-72-7, formula C8H9NaO3S (as the active). The 40% solution grade ships with a Certificate of Analysis and SDS.

What is the cost of bulk sodium xylene sulfonate 40%?

Bulk pricing depends on order volume and packaging (drums, totes, or bulk). Submit a bulk RFQ with your target quantity and delivery point and we will return a current quote with CoA and SDS.
