Nonionic emulsifier for emulsion polymerization

Emulsogen LCN 407

Nonionic emulsifier for emulsion polymerization

Edition Date :
August 10, 2020
Emulsogen LCN 407 is used as nonionic emulsifier for the emulsion polymerization of monomers like acrylates, styrene-acrylates and vinyl acetate. 

The use of Emulsogen LCN 407 offers the following advantages:

Product properties:

  • low VOC
  • free of alkylphenol ethoxylates (APEO)
  • hazard label free
  • readily biodegradable
  • easy to handle (liquid material; soluble in water)
  • FDA approved

Performance in emulsion polymerization:

  • maintains low viscosity of polymer emulsion at different shear rates
  • enhanced electrolyte stability
  • improved shelf life (high freeze thaw stability)
  • similar polymerization results to APEOs

Product group:  Fatty alcohol ethoxylate
Active content: 70%
Appearance: clear liquid
pH value: 6 - 8 
Solubility: soluble in water
Density: approx. 1.09 g/cm3 
Viscosity: approx. 640 mPas 
Crystallisation temperature:  approx. 10 °C
Flash point: > 100 °C
HLB value: 18
Emulsogen LCN 407 is used as nonionic emulsifier for the emulsion polymerization of:

  • Styrene/acrylate dispersions
  • Acrylate dispersions
  • Vinyl acetate dispersions

Dosage level is 2 % based on monomers.

  • Low VOC content (< 1wt.% acc. to ISO 11890-2)
  • Free of human hazard label (non irritant to eye and skin)
  • Free of alkyl phenol ethoxylates
  • Reflects market trend towards low odor waterborne paints having less impact on the environment than solvent borne paints
  • Suitable for hazard-label free formulations (acc. EU/CLP directive)
  • High active content: 70 %
  • Effective at low use concentrations (usage in emulsion polymerization: 2 % active based on monomers; usage in paints: 0.1-0.3 %)
  • Free of environmental hazard label
  • Less impact on aquatic life (LC50 > 500 mg/l)
  • Readily biodegradable (biodegradation > 75 % in 28 days according to OECD 301 D)

  • Assistance in formulation development and regulatory guidance
  • Improves latex quality with longer shelf life
  • Increases scrub resistance in paints
  • Compliant with eco label criteria (European Ecoflower, German Blue Angel, Scandinavian Nordic Swan, French NF Environment)
  • Easy to handle (low solid point and low viscosity of aqueous solutions)
