Sodium caprylyl sulfonate (CAS 5324-84-5), the sodium salt of 1-octanesulfonic acid, is a short-chain anionic surfactant and hydrotrope. It is used as a wetting agent, hydrotrope, and coupling or solubilizing aid in cleaning and personal-care formulations.

Frequently Asked Questions

What is sodium caprylyl sulfonate?

Sodium caprylyl sulfonate (CAS 5324-84-5) is the sodium salt of 1-octanesulfonic acid, a short-chain anionic surfactant and hydrotrope. It is used as a wetting agent, hydrotrope, and coupling or solubilizing aid in cleaning and personal-care formulations.

What does sodium caprylyl sulfonate do in a formulation (use of sodium sulfonate)?

As a hydrotrope and coupling agent it stabilizes concentrated surfactant systems, improves clarity and phase stability, and reduces surface tension as a wetting aid in aqueous cleaners and personal-care products. It is typically a co-ingredient rather than the primary detergent.

Is sodium caprylyl sulfonate the same as sodium octane sulfonate?

Yes. Sodium caprylyl sulfonate is the sodium salt of 1-octanesulfonic acid (CAS 5324-84-5); caprylyl denotes the eight-carbon (octyl) chain. The names refer to the same compound.

What is the CAS and HS code for sodium caprylyl sulfonate?

It is CAS 5324-84-5, formula C8H17NaO3S, classified under HS 2904.10 (sulfonated hydrocarbon derivatives containing only sulfo groups, their salts and ethyl esters). These identifiers appear on the CoA and customs documents.

How is sodium caprylyl sulfonate supplied in bulk?

We supply sodium caprylyl sulfonate for industrial and contract-manufacturing use with CoA and SDS per lot. Request a bulk quote for packaging, container quantities, and current lead time.
