LIOSIL® FC 219 E is easy to mix with fabric softeners.
LIOSIL® FC 219 E improves the softening efficacy of fabric softeners and the fabrics get a significant softer and pleasant touch. With LIOSIL® FC 219 E the hydrophilicity is increased. Additionally LIOSIL® FC 219 E reduces the friction forces of the iron and therefore the ironing properties are improved significantly.
