Lansurf TA15
Product Category: Nonionics
Tallow Amine Ethoxylate with 15 moles of Ethylene Oxide
INCI Name: Tallowamine Ethoxylate
Lansurf TA15 is a nonionic surfactant produced by the alkoxylation of ethylene oxide with tallow amine, yielding a medium‑EO ethoxylate with a strong balance of wetting, detergency, and compatibility across a wide range of formulation types. It is well suited for use in textile processing, metal cleaning, paints, agriculture, and polish manufacture, where reliable wetting, levelling, and surface‑active behaviour are required.
The product exhibits excellent compatibility with nonionic, anionic, cationic, and amphoteric surfactants, enabling use in complex multi‑surfactant blends. In both acidic and alkaline formulations, it functions as an effective primary wetting agent, supporting deep soil penetration, emulsification, and the removal of surface coatings.
​
Key Features
-
Excellent Wetting Performance - Functions as a primary wetting agent in both acidic and alkaline formulations, ​enabling rapid penetration, soil removal, and effective coating or surface‑film stripping.
-
Strong Compatibility Across Surfactant Types - Compatible with nonionic, anionic, cationic, and amphoteric surfactants, allowing easy incorporation into complex industrial formulations and blends.
-
Levelling & Anti‑Precipitant Functionality - Serves as an effective levelling agent and anti‑precipitant in textile dyeing and finishing, ensuring even dye distribution and preventing redeposition.
​​
Applications
​
Processing
- Used as a levelling agent and anti‑precipitant in dyeing and finishing, ensuring uniform dye distribution and preventing redeposition or spotting.
Acidic & Alkaline Metal Cleaning
- Acts as a primary wetting agent in acid and alkaline cleaning formulations, supporting rapid wet‑out, penetration, and effective removal of surface coatings and soils.
Paints & Coatings Manufacture
- Provides wetting and dispersion support in paint systems, improving pigment wet‑out and enhancing formulation stability.
Agriculture (Adjuvants & Formulations)
- Functions as a nonionic surfactant within agricultural adjuvants and crop‑protection systems, aiding emulsification and coverage.
Polish & Surface Treatment Products
- Contributes to wetting and emulsification in polish manufacture and surface care formulations.
Metalworking & Industrial Processing
- Applicable in metalworking fluids and industrial formulations requiring surfactancy, wetting, or levelling.
