Request SDS →Disodium Lauryl Phenyl Ether Disulfonate (CAS 28548-81-4) is an anionic surfactant of the alkyl diphenyl ether disulfonate class. As a disulfonated surface-active agent it is used for wetting, emulsification, and dispersion in aqueous formulations.
Frequently Asked Questions
What is disodium lauryl phenyl ether disulfonate used for?
It is an anionic surfactant of the alkyl diphenyl ether disulfonate class (CAS 28548-81-4) used for wetting, emulsification, and dispersion in aqueous formulations — reducing surface tension, stabilizing oil-in-water systems, and dispersing solids and pigments.
Is disodium lauryl phenyl ether disulfonate the same as Dowfax 2A1?
Dowfax 2A1 is a well-known alkyl diphenyl ether disulfonate (ADPODS) surfactant of this chemical class. Whether a given lot is equivalent depends on alkyl chain and active level; confirm the CAS (28548-81-4) and active specification on the CoA when seeking an equivalent.
What type of surfactant is this and what does disulfonate mean?
It is an anionic alkyl diphenyl ether disulfonate. "Disulfonate" means the molecule carries two sulfonate groups (–SO3⁻), present here as sodium salts, giving high water solubility and electrolyte/temperature tolerance — useful for hard-condition wetting and dispersion.
What is the CAS number and HS code for disodium lauryl phenyl ether disulfonate?
CAS 28548-81-4, representative formula C24H32Na2O9S2; it classifies under HS 3402.39 (anionic organic surface-active agents, other). Identity and active level are confirmed on the CoA, with an SDS per shipment.
How is this surfactant supplied and priced in bulk?
It is typically supplied as an aqueous solution at a stated active percentage in drums, totes, or bulk to industrial and formulation buyers. Active level, packaging, and pricing are quote-dependent; submit a bulk RFQ for a current quote, CoA, and SDS.
