  • Patent number: 5532023
    Abstract: The present invention relates to a wrinkle reducing composition for use on fabrics, particularly clothing. The composition comprises a wrinkle reducing active, which is made up of an effective amount of silicone and an effective amount of film-forming polymer, and a liquid carrier. The composition is substantially free of starch, modified starch, and mixtures thereof, and results a Loss Modulus Difference of greater than about 3.3.times.10.sup.7 Pascal on fabric.The composition can be incorporated into a spray dispenser that can create an article of manufacture than can facilitate treatment of fabric with the wrinkle reducing composition. The wrinkle reducing actives in the composition can be determined through Dynamic Mechanical Analysis using a 100% cotton broadcloth swatch and a fixed volume of a sample of wrinkle reducing active.

  • Patent number: 5368756
    Abstract: Rinse-added fabric softening compositions are provided comprising mixtures of a diester quaternary ammonium fabric softener material, a highly ethoxylated hydrophobic material as a scum dispersant, and a liquid carrier. This mixture prevents the formation of scum caused by the interaction of the diester quaternary ammonium fabric softener material with anionic detergent surfactant and/or detergency builder entrapped in the fabric. These, preferably biodegradable, compositions have good product stability, dispersibility, and concentratability, as well as excellent fabric softening characteristics.

  • Patent number: 4994193
    Abstract: Liquid fabric softening compositions for use in a rinse bath after washing with a detergent. The softening compositions contain certain specific water-soluble, light-stable dyes as colorants at levels which provide consumer acceptable colors. The colorants are added to the finished composition so that the dyes are predominantly outside of the dispersed softener phase, where they remain. The compositions are very desirable in that they are very unlikely to stain fabrics.

  • Patent number: 4897208
    Abstract: Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening compositions contain certain specific oil-soluble light-stable red dyes and pigments as colorants at levels which provide a pink color. The colorants are difficult to incorporate and require better mixing than water-soluble dyes.

  • Patent number: 4844820
    Abstract: Liquid fabric softening composition for use in a rinse bath after washing fabrics with a detergent. The softening composition has a pH of less than about 7 and contains light-unstable red dyes especially D&C Red #28, to provide a pink color, the softening composition being packaged in a container that protects the dye from light. Light destroys the dye on fabrics, equipment, etc. to avoid dye build-up.
