FABRIC SOFTENERS- SHORT HISTORY
First used in the 20ies in the textile industry in order to compensate negative effects of dyeing Typically: water, soap and olive or corn oil
Since the 60ies, successfully offered on end-consumer market
Wacker Silicones for Fabric Care Dr. Richard Becker, J. Kugler, A. Maier, Dr. Elisabeth Gonthier, S-P-I, Household Care, May 2009, Page 3
FABRIC SOFTENERS- SHORT HISTORY
Typically: quaternary ammonium salt with one or two long alkyl-chain
Effects of these esterquats more and more completed with other effects

HOW CAN FABRIC CARE EFFECTS BE INTRODUCED?
Applied through wash cycle
FABRIC-CARE COMPONENTS
Applied through rinse cycle
Wacker Silicones for Fabric Care Dr. Richard Becker, J. Kugler, A. Maier, Dr. Elisabeth Gonthier, S-P-I, Household Care, May 2009, Page 7
APPLIED THROUGH WASH CYCLE
Competition: desorption of soil vs. adsorption of fabric care component
Currently, no satisfying solution has been found
Holy grail of detergents industry: so-called 2-in-1 detergents
Wacker Silicones for Fabric Care Dr. Richard Becker, J. Kugler, A. Maier, Dr. Elisabeth Gonthier, S-P-I, Household Care, May 2009, Page 8
APPLIED THROUGH RINSE CYCLE
after wash cycle is over
together with rinse-cycle softener during the last rinse stage
well-established process for organic based, fabric-care components

WACKER FC 207 micro-emulsion of an amino-modified silicone fluid
can be easily formulated into standard fabric softeners
improves the softening efficacy of fabric softeners and the fabrics get a significant softer and pleasant touch
Additionally reduces the friction forces of the iron and therefore ironing properties are improved significantly.

Many consumers do not use rinse cycle softener due to this hydrophobicity e.g. on terry towelsWacker Silicones for Fabric Care Dr. Richard Becker, J. Kugler, A. Maier, Dr. Elisabeth Gonthier, S-P-I, Household Care, May 2009, Page 17

TECHNOLOGY FOR WRINKLE REDUCTION
Introduction of substantive crosslinkable aminosilicones onto the fabric Crosslinking occurs at an elevated temperature during ironing Fabric is protected against creases Deposited aminosilicone must disappear during next washes

DIN 53895 SELF-SMOOTHING BEHAVIOUR OF TEXTILE FABRICS AFTER LAUNDERING AND DRYING
Procedure: The fabrics are Washed, Rinsed and treated with softener / silicone, Air dried. Illuminated with a standardized shine box. The test fabrics are compared with standard wrinkle replicas (AATCC No. 124-2005).

FASTER DRYING = COST SAVING
Drying of clothes in tumble dryer: less water => less evaporation heat => less energy cost Germany: Average energy costs per drying cycle: 0.65 Euro1 => average German consumer spends 500 Euro for drying in 10 years1
According to Der Spiegel (Heft 6, 2006), average consumer cost per kwh in Germany is 0.185 Euro/kg. Drying cycle consumes 3 - 4 kwh.
Air dried clothes need less time for drying
