  • Patent number: 6099589
    Abstract: In fabric laundry procedures, commercial and household laundry detergent compositions commonly contain an optical brightener composition. Brighteners adjust the optical properties of the fabric in such a way that the fabric appears to be white even after repeated washings. Often white fabrics can yellow during use. Fluorescent optical brighteners having an optical blue aspect, mask the yellowing of the fabric. Common laundry detergents fail to have sufficient brightening capacity to brighten heavily soiled white cotton items used in household, commercial, institutional or fast-food food surface. A process for improving the whiteness of soiled white cotton, preferably terry cloth, items involves contacting the soiled white fabric item with a presoak containing an effective proportion of a fluorescent optical brightener composition, removing the item from the presoak and separating the presoak composition from the fabric item producing an extracted item.

  • Patent number: 5948153
    Abstract: This invention relates to water-soluble complexes of optical brighteners with quaternary ammonium compounds which are substantially free from unwanted salts. Such complexes are formed through ionic bonds formed between the two compounds. The inventive complexes are then removed of substantially all excess unwanted salt so as to obtain an optical brightener compound which easily solubilizes within, dispenses from, and exhibits excellent compatibility with standard detergent and softener compositions, which exhibits the desired degree of affinity for various substrate surfaces, including textile, paper, wood, and plastics, as well as within leak detector formulations, and which provides a desired accumulation effect on substrate surfaces upon repeated treatments. Such inventive complexes can also be utilized to whiten thermoplastics and thermosets. Furthermore, this invention also concerns methods of making and utilizing such inventive optical brightening complexes.
