DISODIUM LAURETH SULFOSUCCINATE- ▸ Cleansing surfactant: Primary or secondary surfactant in liquid cleansers.
- ▸ Foam booster: Builds and stabilizes foam in surfactant blends.
- ▸ Mild co-surfactant: Lowers the irritation potential of harsher anionic systems.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Disodium Laureth Sulfosuccinate (CAS 39354-45-5) is an anionic surfactant, the disodium salt of an ethoxylated lauryl alcohol half-ester of sulfosuccinic acid. It functions as a foaming and cleansing surfactant and as a co-surfactant, and is documented for use in personal-care and household cleansing formulations.
Frequently Asked Questions
What is disodium laureth sulfosuccinate used for?
It is an anionic surfactant — the disodium salt of an ethoxylated lauryl alcohol half-ester of sulfosuccinic acid — used as a foaming and cleansing surfactant, a foam booster, and a mild co-surfactant that lowers the irritation potential of harsher anionic systems in personal-care and household cleansers.
Is disodium laureth sulfosuccinate the same as SLS (sodium lauryl sulfate)?
No. SLS is a sulfate ester surfactant; disodium laureth sulfosuccinate (CAS 39354-45-5) is a sulfosuccinate half-ester — a different anionic class, built on an ethoxylated (laureth) alcohol. They are not interchangeable on a specification; confirm the CAS on the CoA.
Is laureth sulfosuccinate a sulfate?
No. It is a sulfosuccinate (a sulfonate-bearing succinic-acid half-ester), not a sulfate ester. The two differ in their sulfur–oxygen linkage. Verify identity by the CAS, 39354-45-5, on the CoA.
What is the CAS number and HS code for disodium laureth sulfosuccinate?
CAS 39354-45-5, formula C18H32Na2O8S (representative); it classifies under HS 3402.39 (anionic organic surface-active agents, other). Identity and active level are documented on the CoA, with an SDS per shipment.
How is disodium laureth sulfosuccinate supplied in bulk?
It is typically supplied as an aqueous solution at a specified active percentage in drums, totes, or bulk to personal-care and cleaning formulators. Active level, packaging, and pricing are quote-dependent; submit a bulk RFQ for a quote, CoA, and SDS.
