Abstract

A new type of softener was developed, the fabric softening compounds were Noverite™ polymer or Schercoquat™ quaternary compound, or a combination of Noverite™ polymer and Schercoquat™ quaternary compound or Glucquat™ quaternized alkyl glucoside. The softener appearance was crystal clear, and its viscosity was stable over time. Fabric treated with these new types of softener had high hydrophilicity and improved anti-dye transfer from colored cloth to white cloth, and brought high comfort to consumers wearing it. In addition, these compositions minimize the use of extraneous ingredients for stability control, lowering lower chemical load on the environment. The softness was a dry, fluffy softness compared to the greasy softness of traditional esterquats and tallowquats.
