Lanphos TE43

Lanphos TE43 is a phosphate ester based on C12‑15 alcohol + 3EO, manufactured using polyphosphoric acid to produce a product containing predominantly monoester species. The main advantage of phosphate esters over conventional anionic surfactants is their excellent stability in high concentrations of acid, alkali, and electrolytes, making them particularly suitable for demanding industrial applications.

Supplied in acid form, Lanphos TE43 can be neutralised with a variety of bases to produce different salt forms, providing flexibility for formulation development and performance optimisation. The product exhibits excellent tolerance to challenging formulation conditions where conventional surfactants may lose effectiveness.

Lanphos TE43 provides a balanced combination of wetting, detergency, lubricity, and emulsification properties. Its versatility makes it suitable for a wide range of applications including industrial and institutional cleaning, emulsion polymerisation, textile processing, agrochemicals, and speciality chemical formulations where electrolyte tolerance
and formulation stability are critical.

Applications

 

Lanphos TE43 is used in a wide range of industrial applications where excellent electrolyte tolerance, wetting, detergency, and emulsification are required, including:

Industrial & Institutional (I&I) Cleaning
– Used in highly built detergent formulations containing high levels of caustic soda, silicates, and other builders, where conventional surfactants may lose performance.

Emulsion Polymerisation
– Functions as a primary emulsifier in polymer systems, particularly those intended for coatings applications where strong surface adhesion and formulation stability are required.

Textile Processing
– Acts as a wetting agent and detergent in textile formulations, providing effective performance under high‑electrolyte and high‑pH processing conditions.

Agrochemical Formulations
– Used as an emulsifier, dispersant, and compatibility agent in agrochemical systems where electrolyte tolerance and formulation stability are critical.

Lubricants & Metalworking Fluids
– Provides emulsification, lubricity, and surface activity in speciality lubricant and metalworking formulations.

General Industrial Formulations
– Offers good wetting, detergency, lubricity, and emulsification properties, making it suitable for a wide range of speciality chemical applications requiring robust performance under demanding conditions.
