Description
Potassium 3-(phenylsulfonyl)benzenesulfonate, commonly known as KSS and marketed under trade names including F 507 and Chemguard KSS, is an anionic sulfonate surfactant with the molecular formula C12H10O5S2.K. It carries no assigned E-code and is registered under EC number 264-097-3.
In textile processing, KSS reduces interfacial tension between fiber surfaces and aqueous dye baths, improving dye penetration and leveling. In printing and packaging applications, it functions as a wetting and dispersion agent, helping pigment particles distribute uniformly across coated substrates. Leather processing operations use it to assist emulsification of fatliquoring agents during retanning stages.
KSS is supplied as a white to off-white powder and is subject to REACH registration requirements for suppliers placing it on the European market. Buyers should confirm substance identity against CAS 63316-43-8 when evaluating technical datasheets. Packaging formats and minimum order quantities vary by supplier and should be confirmed at the time of enquiry.
