The final viscosity of a liquid fabric softener depends on temperature, mixing rate and pH. The viscosities listed above are those obtained in the lab. Calcium chloride can be used to reduce viscosity. Fabric softeners made with an Accosoft product are non-yellowing, control static and maintain rewet properties of the fabric. 

Charge water. Heat to 80F. Add propylene glycol and IPA with mixing. Slowly add 550 HC while mixing until homogeneous. Properties

POMOSOFT 54 Base is a highly concentrated cationic softener, designed primarily for use on acrylic yarn or fabric. It is a semi-soft waxy solid, and needs to be diluted before adding to the dye machine or pad bath. 

VARISOFT 222LM-(90%) is a more fluid and cold water dispersible version of VARISOFT 222-90%. It is designed to be used in the formulation of regular rinse, concentrated rinse, and high solids aqueous dispersions. Water at temperatures as low as 55F can be used to formulate these liquid rinse cycle fabric softeners. Its versatility simplifies inventory control of the base, yet offers much formulation flexibility.

Silica is appropriate with the cationics used in fabric softeners because their highly nonpolar character makes them suitable for normal phase chromatography. Adsorption of cationics on silica is more favored at high pH, usually 9-10. Silica is rarely used in solid phase extraction of surfactants because of the difficulty in removing the surfactant for subsequent analysis. Ethoxylates are particularly tightly bound, but low yields are found also with other surfactants. PEG is most tightly bound of all, and is best separated using Cm media.
