LIOSIL® FC 201 E is a nonionic 60% Polysiloxan emulsion for fabric softeners. LIOSIL® FC 201 E is a one-component system which is cross-linking at higher temperatures.

Therefore LIOSIL® FC 201 E protects textiles, especially cotton-polyester union cloth, for wrinkles and improves handle and easy ironing properties.


Specific features of LIOSIL® FC 201 E

  • Emulsions
  • Technical grade

LIOSIL® FC 201 E is combined with conventional fabric softeners.

Due to the special composition LIOSIL® FC 201 E is polymerizing to a high molecular polysiloxane while ironing. The fabrics get elastic shape stability and therefore a protection against wrinkles.

Even without ironing LIOSIL® FC 201 E improves the softness of fabrics.

Additionally LIOSIL® FC 201 E reduces the friction force of the iron and therefore the ironing properties are improved significantly.



Preferably LIOSIL® FC 201 E is mixed with the fabric softener at the end of fabric softener production by stirring gently.

Example for a fabric softener with LIOSIL® FC 201 E:

  • 20,0 parts esterquat, e.g. Stepantex VK 90 (50°C) are poured slowly in
  • 74,6 parts demineralized water (50°C) while stirring until the mixture is homogenous.
  • 0,4 parts CaCl² solution (25%) are added
  • q.s. perfume, dye, preservative are added
  • 5 parts LIOSIL® FC 201 E are mixed while stirring.


Dosage recommendation: Approx. 3 - 9 % LIOSIL® FC 201 E in the fabric softener formulation.

The dosage of LIOSIL® FC 201 E in the fabric softener depends on the desired effects.
As desired the amount of the organic softener can be reduced with the rising amount of LIOSIL® FC 201 E.


The 'Best use before end' date of each batch is shown on the product label.
