Lanphos PE104

Lanphos PE104 is an anionic phosphate ester surfactant produced from isodecanol ethoxylate containing an average of four moles of ethylene oxide. It is supplied in the acidic form and can be neutralised with a suitable base to produce the corresponding anionic surfactant salt. 

​

It provides excellent wetting, emulsifying and dispersing performance, along with broad compatibility with nonionic, anionic and amphoteric surfactants. This makes it highly versatile across a wide range of formulation types. 

​

Lanphos PE104 delivers strong oil-in-water emulsification and enhanced detergency, combined with beneficial corrosion-inhibition properties. These attributes make it especially suitable for use in hard-surface cleaners, industrial and institutional degreasers, agricultural adjuvants, emulsion polymerisation systems, textile auxiliaries and waterborne coatings. 

​

Key Features

 

• Excellent wetting and detergency for rapid soil penetration and superior cleaning performance.

• Strong oil‑in‑water emulsification, ideal for mineral oils, paraffins, agrochemicals, and industrial soils.

• High compatibility across surfactant types, enabling flexible formulation in cleaners, coatings, and polymer systems.

• Corrosion-inhibition properties on both ferrous and non-ferrous substrates.
