Lanspec EMP404
Tridecanol + 40EO alcohol ethoxylate
INCI Name: Trideceth‑40
Lanspec EMP404 is a nonionic alcohol ethoxylate based on tridecanol + 40EO, specifically developed as a latexstabiliser for emulsion polymerisation systems. It is designed to improve the stability of emulsions produced using anionic primary emulsifiers, helping to maintain consistent particle distribution and long‑term latex stability.
The product is an effective replacement for nonylphenol ethoxylates in the 20–50 mole range and is recommended for use alongside anionic emulsifiers such as Kemsurf ESD60, Kemsurf ESD, Kemsurf EM9, and Kemsurf OS38. Its high HLB value and excellent water solubility support robust stabilisation in a wide range of polymer systems.
Lanspec EMP404 provides excellent emulsification and stabilisation performance in emulsion polymerisation processes, helping to improve latex quality, storage stability, and formulation consistency. It is particularly suitable for vinyl acetate, vinyl acetate‑acrylic, styrene‑acrylic, and acrylic monomer systems where reliable nonionic stabilisation is required.

Applications
Lanspec EMP404 is used primarily as a nonionic latex stabiliser in emulsion polymerisation systems, including:
Vinyl Acetate Homopolymer Systems
– Improves latex stability and helps maintain consistent particle distribution throughout the polymerisation process.
Vinyl Acetate – Acrylic Emulsions
– Acts as a nonionic stabiliser alongside anionic emulsifiers to enhance storage stability and formulation robustness.
Styrene – Acrylic Emulsions
– Supports stable emulsion formation and helps improve long‑term latex stability in styrene‑acrylic systems.
Acrylic Monomer Systems
– Suitable for acrylic ester and acrylic acid‑based polymer systems where reliable stabilisation and emulsification are required.
Latex Stabilisation
– Used in conjunction with primary anionic emulsifiers such as Kemsurf ESD60, Kemsurf ESD, Kemsurf EM9, and Kemsurf OS38 to improve emulsion stability and overall latex performance.
Nonylphenol Ethoxylate Replacement
– Provides an effective alternative to nonylphenol ethoxylates (20–50 EO range) in emulsion polymerisation applications requiring nonionic stabilisation.
