These are formulas for Fabric Softeners with Rewoquat® WE 45, which exhibits a pleasant and soft hand, good rewet, and a noticeably reduced static charge. Fabrics treated with Rewoquat® WE 45 show a significantly reduced drying time compared to untreated fabrics.

Typical fabric softener formulations for home laundry use will contain from 6% to 23% Rewoquat® WE 45, or 5% to 20% active quaternary. Stable aqueous dispersions are easy to prepare.

Rewoquat® WE 45 can be used at lower temperatures than conventional TEA Ester Quats, however, the product should be thoroughly mixed before use. Mixing equipment should be 316 stainless steel, glass-lined, or chemical resistant polyester. Aluminum and mild steel should be avoided.

 

Fabric Softener (18%)

Sequence Trade Name INCI Name %
Rewoquat® WE 45 Quaternary ammonium compound 20.93
Water to 100
Fragrance 0.70
CaCl2 0.20-0.70
Dye

 

PROCEDURE:

  1. Heat the water to approximately 25°C. Add dye and antifoam if required.
  2. Slowly disperse in Rewoquat® WE 45, preheated to approximately 25°C, adding CaCl2 solution as needed to maintain a good processing viscosity.
  3. Stir for about 10 minutes then add fragrance. Adjust to the required final viscosity with CaCl2. The stability and viscosity of the finished dispersion will be affected by water quality, mixing conditions, temperature, pH, and additives.
