Frequently Asked Questions
What is sulfated alkylphenol ethoxylate (ammonium salt) used for?
This material is the ammonium salt of a sulfated alkylphenol ethoxylate, an anionic surfactant used as an emulsifier for industrial emulsion systems (including emulsion polymerization), as a wetting agent that reduces surface tension in industrial formulations, and as a cleansing/detergency surfactant in industrial cleaners. CAS 68649-55-8. It is supplied as an aqueous active for formulation.
What is alkylphenol ethoxylate sulfate made from?
It is produced by ethoxylating an alkylphenol, sulfating the resulting ethoxylate, and neutralizing with ammonia to form the ammonium salt (CAS 68649-55-8). The alkylphenol hydrophobe gives strong emulsifying and wetting performance. Request the CoA and SDS for the specific grade and active level.
What is the difference between this and an alcohol ethoxylate surfactant?
This is a sulfated (anionic) alkylphenol ethoxylate carrying a charged sulfate group, whereas alcohol ethoxylates are typically nonionic and built on a linear alcohol rather than an alkylphenol. The anionic charge here aids emulsion stabilization and detergency. Select based on charge type, substrate, and formulation compatibility.
What is the CAS number and HS code for this surfactant?
This ammonium salt of sulfated alkylphenol ethoxylate is CAS 68649-55-8, an anionic surfactant classified under HS code 3402.49. Active concentration is defined per lot on the Certificate of Analysis. Confirm the assay before formulating.
How is this surfactant packaged in bulk and priced?
It is supplied in drums, totes, and bulk to industrial manufacturers and formulators. Pricing depends on active concentration, volume, and packaging, so request a bulk quote rather than a list price. The SDS and CoA accompany the quote.
What is the REACH and TSCA regulatory status of Ammonium Salt of Sulfated Alkylphenol Ethoxylate?
Ammonium Salt of Sulfated Alkylphenol Ethoxylate (CAS 68649-55-8) is listed as Active on the U.S. EPA TSCA Inventory; its REACH registration status is not determined from the public ECHA registry.
